Ten Most Beautiful Moments of Football World Cup 2006

These moments are not in any order but a symbol of how they enhanced the beautiful game.

1. Togo’s players celebrating their first goal in the world cup against South Korea in their opening match.

2. Philip Lahm perfect goal against Costa Rica in the 6th minute led way to a high scoring World Cup.

3. Argentina second goal against Serbia & Montenegro arguably one of the best goals in world cup history. It constitutes 24 passes, a backheel to create space in the 18 yard box, 8 outfield players touched the ball in the move and a superb finish by Cambiaso.

4. Maxi Rodriguez superb volley in extra time to dispose off Mexico in round 16 is one of the most beautiful goals at such crunch stage.

5. Koreans fans cheering their team will all noise making instruments and continuously jumping for 90 minutes to test the suspensions of the stands.

6. Mexican fans singing their national anthem with salute like star trek and erupting in Mexican wave.

7. Zidane celebration after scoring goal against Spain reminded a Spanish bull just released from shackles into a green field.

8. Huge success of fan mile and jovial nature between fans from across the world.

9. Carlos Tevez goal against Serbia Montenegro after dribbling two players and slotting the ball into left corner of goal keeper.

10. Diego Maradona supporting Argentina team like no other superstar ever did. He reminded us of a school boy out there to enjoy football.

Review of PC Diagnostic Shareware

Although, the most popular operating system at the present includes a sort of Computer diagnostics tools, such as PC Health, Dr Watson, and others, those applications are not exactly what the consumer expects from a full PC diagnostics suite to protect their costly equipment an the invaluable information contained within.

There is a large number of PC diagnostics software offered on a shareware basis. This software is usually provided fully functional for a limited period of time to allow consumers to test the features and if the program fulfills their expectations, the programmer typically is paid a one-time fee. Some of those PC diagnostics applications offered under this mode are:

TuneUP Utilities

Computer diagnostics applications provided by TuneUp Software

International, one of the pioneer companies in PC diagnostics software since 1997, and the top utility producer in the German speaking area of Europe. From its headquarters in Darmstadt, a city close to Frankfurt, Germany, TuneUP Utilities has literally “saved the life” of many computer systems by detecting conditions that can be easily fixed by the end-user.

As of 2006, more than 300,000 copies of TuneUp 97, the original, has been sold, creating one of the most successful PC diagnostics utilities available on the German market, usually referred as the mother of all tuning and computer diagnostics tools. With the release of PC diagnostics TuneUp Utilities 2003 the product was introduced internationally.

Today, the acclaimed TuneUP Utilities 2006 PC diagnostics software is available in German, French, Dutch and English language, as innovative as the first day, offering one of the most complete and friendly computer diagnostics solutions, with free trials software and affordable registrations fee.

Energy and America

America is entering into a time of Energy crisis. It
could easily be the greatest crisis that human-kind is
to face. America can not continue to lead the world
econimcally and drain it dry at the same time.
The National Collegiate Clean Energy Initiative is
working to unite American students and citizens alike,
to demand CLEAN ENERGY POLICY.

The FED Chairman, Mr. Alan Greenspan was on
capitol hill in the semi-annual monetary policy
meeting with congress. (also known as the Humphrey
Hawkins meeting)While Mr. Greenspan was mostly upbeat
about the economy (Note: I am not as up beat) he made
some very troubling remarks.
Mr. Greenspan commented that the…”Long-term futures
for crude oil…going 10-years out…have risen
substantially in the last few years…and are being
sustained at these levels…”
Now… the market is a discounting mechinism. Has the
futures market begun to discount PEAK OIL? I believe
the answer is YES! In REAL DOLLARS, crude needs to get
over $100/brl to equal the peak of the 70’s crunch.
It is extremely crucial that clean energy comes to
market NOW – being infront of this curveball will
determine our future and the state of our economy.
What is just as troubling is that I have not heard any
covering of this in the media.

ENERGY ESP #2
I believe the greatest crisis that Human-Kind has ever
seen has begun. America, a country founded on the
basis of freedom is under attack by unstoppable
inflating energy prices, and it has just begun. The
situation in the middle-east is escalating with no end
in sight, as relations with the OPEC countries has
begun to fall apart. Believing the promises of Saudi
Oil is not an option. With horrifying accounting
scandals of greed in our country…. who truly
believes that the OPEC countries will be honest with
us regarding the oil reserves; or anything else for
that matter?! It is common knowledge of the recent
events at Shell and their false statements of
reserves. It will not stop there I’m sure. While Saudi
Arabia has been pumping water to flush out oil from
their depleting reserves since the mid-late 90’s . . .
more problems are developing. Americans are being told
to leave the middle-east. We all know that we need
those Americans in the OPEC countries in order for us
to actually get the oil to American soil. Should
America, the largest and most powerful nation in the
world be relying so much on foreign energy?

From an Economic point of view, RENEWABLE ENERGY, such
as wind and solar energy will be a long-term net
positive, not only for Long Islands’ economy . . . for
the nations’ economy as well. Just as in the Aviation
industry many years ago, Long Island became the
National Economic Leader and was looked upon with
great admiration. Long Island Thrived. It will take
two years to begin construction of the wind park off
Jones Beach. By that time, oil prices will be much
higher then where it is now acting as a devastating
tax on American Citizens. This is a once in a lifetime
opportunity must not be missed. It simply makes
dollars and sense.

The DOE predicts that the price of Crude Oil will
climb until around the year 2025 and then peak. If
true this means that Peak oil is now. Supply has
already begun to decline as not one OPEC country has
claimed new oil finds. Let us not forget the two wild
cards; China and India. America is now at the mercy of
two countries growing by leaps and bounds. We have no
control and it has only begun to effect us all. In
terms of REAL dollars, to reach the equivalent price
of oil during the energy crisis of the 70’s. Oil
would need to go to over $100 dollars a barrel. $40 is
simply a drop in the bucket.

Supply is going down – Demand is going up. This is the
current long-term situation and it is not going away -
UNLESS.
Wind Power will give Long Island Independence from the
volatile and raising energy prices ahead. It will give
stability to our children and our grandchildren. It
will give them a chance.

on…. my eyes were flooded. This is not the same
world that we were born into… and I for one… am
scared for my children.”
On behalf of students across the country who are
fighting for the future, on behalf of the National

The National Democratic Convention began on Monday as
President Clinton gave his usual “Reagan-like” speech.
It has been interesting to listen to all of the
members of the Democratic party give praise for John
Kerry as the next President of the U.S.A. What has
been more interesting is listening to the united
conviction towards “clean energy,” “energy
independence and energy sustain-ability.” In almost
every speech that included policy, “clean energy” and
“energy independence” or simply a good “energy policy”
was numero uno.
The Electric Power Research Institute estimates that
power outages and power quality disturbances cost
businesses in the U.S. more than $120 billion a year.
This goes hand and hand as the infrastructure is older
than my grandfather.
In the New Growth Initiative Apollo Alliance for
Energy Independence plan, bio-fuels and energy
efficiency investments alone could produce over one
million jobs by 2015.

Tonight, John Edwards will speak to the country. Will
“clean energy” and “energy independence” be on his
agenda?

Every time President Clinton spoke of the future of
jobs, the first industry on the list was the “clean
energy” industry.
Now . . . by no means do I anticipate the republican
convention to be any different. Do you?
Stay tuned for a complete breakdown of the NATIONAL
COLLEGIATE CLEAN ENERGY INITIATIVE’S positions’ on
Clean Energy policy…or lack there of.

Crude oil is now at $43 per barrel reaching new highs.
Or Are they. Lets not forget that about $114 is the
actually peak of the Yom-Kippour War. My how short the
human memory could be. John Kerry gave an emotional
speech full of great rhetoric. In the last ESP I was
waiting to listen for ENERGY information. What will he
do? When will he do it? When time came to talk policy,
he said he was going “say something FDR couldn’t do at
his speech,… goto JohnKerry.com” So JohnKerry.com it
is…

What did we find? “…Investing in future technology,
today…” Fuel Cell vehicles were mentioned. Clean
Energy efficiencies…” yadadad… Nothing truly in
depth as I had hoped for. I remind you,reader, that
this is a NON-PARTISAN effort to advocate for CLEAN
ENERGY. With that said…why do you goto JohnKerry.com
then goto Georgebush.com and see if there is a button
on their site called “Energy.” When you find it…read
and compare. THIS IS IMPORTANT!!

So needless to say I was a little let down at the
level of importance that Clean Energy and Renewable
Energy was given. THAT, my fellow advocates…is why
there is now the NATIONAL COLLEGIATE CLEAN ENERGY
INITIATIVE.
Soon…very soon, a massive email campaign will begin.
It will go to many student organizations around the
country. But until than, much work needs to be done.

ENERGY ESP #5
There is a lot of talk as of late about something
called “clean-coal.” Kerry promises 20% of the
countries electricity via renewable energy sources
proposing “clean-coal.” Is there such a thing? YES!
A company by the name of Headwaters Inc. (HDWR on the
NASDAQ) based in South Jordan Utah, Headwaters seems
to be leading the way in creating a “clean-coal”
environment. Through it’s subsidiary Coval Fuels, a
coal based synthetic fuel is available that is “safe,
odorless and easy to handle. They do not increase
HAPs, VOCs, Sox or Nox emissions and do not fall under
any hazardous material regulations.”

Attorney Generals from eight states including New
York, Iowa and California file lawsuit last month
against utilities including Cinergy Corp., Xcel
Energy, and Southern Company just to name a few, for
dumping a stagering 10% of the countries emitted
greenhouse gases. The question is simple. Did they
know what they were doing? Did they know these gases
were harmful to people? Did they care? Apparently they
are not being fined for anything from the past. They
are simply being asked to decrease harmful emissions.
Is that enough? Shouldn’t there be some kind of
accountability? Why… remember when the EPA was first
formed. We knew then that talons killed.

Global Warming said to be responsible for an
ecological catastrophe as the coastal waters of
Scotland warm. Scores of skuas, terns and guillemots
(all birds) are not breeding. The small fish they eat
is moving closer to colder waters, hence there is not
enough food. “Just a foretaste of what lies ahead,” -

Fed raises Discount rate 1/4%…why not…
Crude now at $44.5… and the charts spell “higher” -
plan and clear. Commodity prices have stabilized in
the past months… – only a buying opportunity in my
view. Lets not forget… we’ve entered into a SECULAR
BULL MARKET IN COMMODITIES!!

Yukos up in the air! Accounts frozen one minute… not
frozen the next. Which is it going to be Mr. Putin?
I’m sure he doesn’t mind the price of crude going
higher… Mr. Putin figures… Russia has more oil
then people think… if you include all that
wilderness over there and lets not forget about
Putins’ attempts to tap into the potential oil under
those frozen (or not so frozen anymore) ice-caps. So
when crude is at $100/brl they will have some amazing
crude finds…I’m sure. It would be nice… since
there hasn’t been any oil reserve finds in how
long…?

Can anyone find any oil from Iraq yet… not me…
they keep having to shut-down plants… you know…
that terrorism thing.

Lets talk about ETHANOL – How much money could the
farmers make if the farmers could farm ethanol? How
about turning all that High Fructose Corn Syrup into
Ethanol instead??? Do you know the average person
consumes 63lbs of HFC per year. Oh we’re fat alright!
Allocation of resources… Allocate more farmed corn
to produce Ethanol… instead of HFC. Think Coke will
go for that?

When ever NCCEI hears about an ENVIRONMENTALLY
friendly company we will do our best to spread the
word…

New Belgium Brewing Company, from Ft. Collins CO. is
the first American Brewery to be powered by 100% WIND
Energy. New Belgium is also proud of it’s recycling
efforts. The best part is… this is an employee owned
company. The employees voted to forgive some of their
profit sharing plan (options) in order to make this
happen. WAY TO GO!!!! And guess what…profits are
up!!
The company is gaining market share as Beer drinkers
are paying attention. This is a perfect example of the
long term economic benefits to using a 100% renewable
energy source. Don’t let me forget the energy company
supplying the power – VESTAS.
VESTAS Wind Systems A/S – This Denmark based global
leader in Wind generation sure is making a name for
it’s self. Keep up the good work!!

Major League Baseball Jeopardizes 2006 Season for Nationals

“Given my travel schedule and steroids and everything else, I’ve been sidetracked.” This was a quote from Major League Baseball’s Commissioner, Bud Selig, as given to the Washington Times on November 18, 2005. He was referring to the ongoing interview process of potential ownership for the Washington Nationals baseball team which was re-located to Washington, D.C. from Montreal, Canada, just prior to the 2005 season and now makes RFK Memorial Stadium its temporary home. But Mr. Selig’s quote only references part of the ongoing troubles of a ball club in total limbo, forcing it into a state of unpreparedness for the 2006 MLB season.

Not unlike the on-again off-again dash to finalize an agreement with the city of Washington, D.C. in December of 2004, the end of 2005 looms as a potential death knell to getting a stadium built, a lease agreement finalized and the installation of an owner or ownership group in the near future. In order for a General Manager, field manager and coaches to be named, the future owner must be chosen and ratified by 29 MLB owners. As long as MLB continues to haggle over the 2004 agreement with the city of Washington, D.C., which was rushed and was arguably a poorly drafted document according to D.C. City Council members and community activists, the Washington Nationals have less and less opportunities to sign free agents and attract management personnel.

The agreement made between the city of Washington, D.C. and MLB last December was dependent upon the city to build a stadium for the Nationals by 2008. In order to do so, the city must raise the capital through the sale of bonds to publicly finance the $535 million price tag. However, the cost of the stadium has risen due to unanticipated construction and raw material expenditures and now the key features which the original plans called for such as an underground parking garage, escalators and elevators, improved roads outside the stadium and expanded Metro train platforms, jeopardize the success of not only the stadium but the gentrified area surrounding it.

The aides of Mayor Anthony Williams, who negotiated the stadium agreement with MLB, estimated that the stadium of 41,000 seats would cost $395 million. However, no money was allocated for infrastructure such as the roads and Metro platforms as they assumed that the federal government or Metro itself would pick up the tab. Additionally, Natwar M. Gandhi, the city’s CFO, raised the estimated cost since the water for the stadium was not included in the original agreement. The architects chosen for the stadium’s design also escalated the original cost of $244 million to $337 million as land costs could now be as high as $98 million, but not certain. The ceiling now for the stadium, based upon whose calculator you believe but supposedly set by the City Council, now stands at $535 million.

With a final stadium architectural plan still yet to be approved, the mayor believes that either MLB, the federal government, private developers or even the new owner should pick up the tab on the ancillary costs not accounted for in the $535 million bargain. Should MLB, private developers or the federal government not chip in, then the taxpayers of Washington, D.C. will be left holding the bill for the balance, which was what started all of the arguments a year ago. Therefore, millions of dollars earmarked for other projects for the city of Washington, D.C., such as improvements in homeland security first-responders, would be sacrificed.

But it gets better. Have your eyes glazed over yet trying to comprehend the numbers? Well, here are some more. Also holding this whole thing up is a $6 million lease agreement which the city says that MLB is responsible for but is being contested by MLB. And the stadium’s financing is contingent upon the lease agreement as bond raters will not provide grade ratings until the agreement has been executed. The complete financing plan must be in place prior to Christmas 2005 in order to begin the process of selling bonds. It will be another race to the finish line much like last year. However, had not Bud Selig procrastinated last year there would not have been such a rush in the end and the agreement would have had more time given for better cost estimates and more time for bids on an architectural design. Such failures have come back to haunt the Nationals a year later.

At issue with the lease agreement is MLB’s argument that the lease agreement must be in place prior to selecting a new owner for the team, while the city wants a guarantee in writing that MLB will pay $6 million a year for the lease of the stadium. Yet, MLB says the agreement was to have included money for the lease. In addition, the city is asking for a $24 million letter of credit from MLB in the event the stadium cannot be completed due to a terrorist attack, natural disaster, or even a MLB strike. And should other resources fail to come through, they are also requesting MLB for an agreement of $20 million for the underground parking.

But the missing quotient in this whole scenario is the missing owner. Had there be an owner in place by now it would then be up to such owner whether or not they want to pay for a lease. At the very least, they could offer input on the design of the stadium and cost containment and work directly with the city rather than the city indirectly asking promises of MLB, which may never come to pass.

But Selig has been “sidetracked.” MLB has missed six of its own self-imposed deadlines to appoint a buyer for the team. To date, Commissioner Selig has only interviewed five of the eight interested groups having failed to address any more prospective candidates since September. So is that the fault of the city of Washington, D.C. too? First Selig said he would choose an owner by the spring of 2005, then it was the 4th of July, only to replaced by the date of the All Star Game, and since then we have seen the date of the beginning of the MLB playoffs, the World Series, and the November owners’ meetings come and go as other promised deadlines, to no avail.

The reality is, that regardless of the details of the agreements on construction and financing, the longer MLB drags its feet on getting an owner in place for the Nationals, the closer it gets to the 2006 season without management in place. And as it is the prerogative of the new owner to choose new management, without it, deals and trades cannot be accomplished. Manager, Frank Robinson, as well as General Manager, Jim Bowden, are twisting in the wind regarding their jobs. But even more importantly, and even if they are dismissed, it will take time for any new manager or General Manager to get organized let alone basically re-build the team all over again. New players are not looking to go to a team with no management or guarantees of potential salaries or management’s ability to ensure that a good team awaits blue-chip free agents.

As good as the Nationals were in their over-achieving first half of 2005, with a 50-31 record, they tailed off dramatically after the All-Star break with a record of 31-50. Nevertheless, they finished with a .500 record. But trading for additional personnel was part of the problem during the season and is crucial to the Nationals now. For a team being sold by MLB in the amount of $450 million, a payroll of $50 million pales in comparison.

“It’s not fair to this ball club and this organization to be put in this position for the coming season because we’re behind on moves and things we can do and approaching players, the free agent market, either signing free agents or even really seriously talking to them. Just overall, the feeling and the atmosphere around this ball club is that we’re at a disadvantage,” according to manager, Frank Robinson. He has been the consummate professional in taking over the helm of the disenfranchised Montreal Expos and now Washington Nationals during the past four seasons, which initially was to be a one-year deal for him and then perhaps going to the front office to help manage the transition between cities and the release of MLB ownership of the club to a new owner.

Frank Robinson’s coaching staff has been directed by Jim Bowden to start looking for new jobs. This has also angered Frank, and the Nationals are very close to losing Robinson, even if the new owners wish to retain his services. He has worked with virtually no payroll, and in two different cities in two different countries, for four years. And in one of those years his team played a third of their games in Puerto Rico. But Robinson is not the only upset party in this twisted tale, which could largely have been avoided. The Mayor of Washington, D.C. is upset, certain members of the City Council are at odds, the residents of Washington, D.C. are concerned with absorbing potential cost overruns, and the candidates who want to own the team are anxious.

Finally, the players, manager and coaches of the 2005 Nationals deserve better and fans of MLB are being taken for granted. Without ticket prices set nor a television contract in place it will be difficult to continue to generate as much interest in 2006 as in 2005 in Washington, D.C., since fans want a good team put on the field too. And now that its maiden voyage is over, any success the Washington Nationals enjoy in 2006 will be in spite of Commissioner Selig, not because of him.

Cisco CCNA Certification: The (Many) Different Kinds Of Switching

When you’re studying for your CCNA exam, whether you’re taking the Intro-ICND path or the single-exam path, you’re quickly introduced to the fact that switching occurs at Layer 2 of the OSI model. No problem there, but then other terms involving switching are thrown in, and some of them can be more than a little confusing. What is “cell switching”? What is “circuit switching”? Most confusing of all, how can you have “packet switching”? Packets are found at Layer 3, but switching occurs at Layer 2. How can packets be switched?

Relax! As you’ll see in this article, the terms aren’t that hard to keep straight. Packet switching, for example, describes a protocol that divides a message into packets before they’re sent. The packets are then sent individually, and may take different paths to the same destination. Once the packets arrive at the final destination, they are reassembled.

Frame switching follows the same process, but at a different layer of the OSI model. When the protocol runs at Layer 2 rather than Layer 3, the process is referred to as frame switching.

Cell switching also does much the same thing, but as the name implies, the device in use is a cell switch. Cell-switched packets are fixed in length. ATM is a popular cell-switching technology.

The process of circuit switching is just a bit different, in that the process of setting up the circuit itself is part of the process. The channel is set up between two parties, data is transmitted, and the channel is then torn down. The circuit-switching technology most familiar to CCNA candidates is ISDN.

Don’t let these terms confuse you. The four different terms are describing much the same process. The main difference is that they are occurring at different levels of the OSI model, and using a different transport method to get the data where it needs to go.

Prepare Your Shoulders for Golf

The golf swing places high demands on the shoulders. The repetition of the swing also helps to make the shoulder a prime target for strain and injury. Stretching and improving the muscular strength of the shoulder area can do much to not only improve and prevent injury, but it can also improve your golf swing.

Repeated motion of the golf swing over many years may irritate and wear down the tendons, muscles, and surrounding structures of the shoulder. The resulting conditions may be tendonitis, bursitis, and impingement syndrome of the shoulder. These conditions may occur alone or in combination.

As always, prevention is the best cure. Exercises that involve stretching and strengthening the muscles in the shoulder area are a good way to help to prevent common shoulder problems. If one of the above problems is present, once inflammation has subsided, exercises will help to restore normal movement.

Stretching your shoulders is important to perform before practice or a round of golf. Most golfers don’t spend adequate time stretching and warming up the muscles before play. This can easily lead to strain, injury, and poor performance on the course. Unconditioned muscles become weak and inflexible causing them to be more susceptible to strain and injury.

Here are a few exercises to help strengthen and maintain more flexibility in the shoulder area.

Back Cuff Stretch – Place left hand on right elbow and right hand on left shoulder. Gently pull back right arm. Repeat on left. Hold for 15 -20 seconds.

Front Cuff Stretch – Hold your hands behind your back and slowly raise your arms. Don’t bounce. Hold for 15-20 seconds.

Rotator Cuff Exercise – Do 20 slow arm circles to warm up. Hold a small dumbbell in each hand. Point thumb down and raise arms out to the side and slightly forward. Do not raise past shoulder level. Repeat 10 times.

Use A Golf Training Club To Quickly Improve Golf Swing Speed

Using a golf training club is one of the most effective ways to increase golf swing speed and power. You can’t get anymore golf -specific than using a golf training club.

There are many golf training clubs on the market and new ones coming out every year; but the one I’m talking about is a weighted golf training club. When you can literally mimic your athletic movement with resistance, you stand the make the biggest improvement…and quickly.

The goal of most strength coaches and trainers is to come up with exercises that closely resemble that particular athletic movement, but with some for of resistance. It could be handweights (dumbbells), medicine balls, tubing, or even a stability ball.

The direct impact on a golfers swing using a golf training club is an almost immediate increase in driving distance. This is because you are training your golf muscles during the movement, through the same (or even bigger) range of motion, with many repetitions.

A secondary benefit of using a golf training club that’s weighted is promoting an increase in backswing and follow through range of motion. This equates in more power at impact. Golfers are always trying to find ways to improve golf flexibility and power; and this is one way to do it.

Using a golf training club won’t be the cure to all your physical ailments and limitations, but will give you a head start on swinging with higher clubhead speed.

Just think about it! Swinging a golf training club won’t improve hamstring flexibility, nor will it strengthen your lower back. There are many specific areas of the body that don’t get worked when swinging a golf training club.

This is where you would do specific golf exercises, stretches and drills to isolate those weak areas to greatly improve your overall golf performance and prevent future injuries.

Another benefit of a golf training club that’s weighted is a quick warm up before you hit balls at the range or even play. Swinging it 20-30 times will quickly get your golf muscles prepared to hit balls more effectively.

Just beware! When you swing it before practicing or playing, you’ve got to swing your regular clubs, and hit balls with them, to make sure your sequence of motion is correct, before you hit the course.

As you can see, there are many benefits of using a golf training club; so go out and get one. They are a great training aid as part of your ‘off-season’ training program.

Are the NFL Playoffs Still Exciting?

The most storied of the possible AFC Championship games would have been a matchup between the Colts and Patriots. There is a tremendous amount of history between these two teams in the playoffs and the media would have been in a frenzy if these two teams were squaring off.

The more exciting teams of the NFC would be the Bears and Giants because of their big market appeal. Instead, the NFC has a Seattle team that few care about and a Carolina team that is new to the NFL.

One can definitely make the argument that this year’s NFL Playoffs is shaping up to be a less than spectacular football season for the media but for the average fan, it is far more exciting.

Nobody can deny the great season the Broncos have had at home. Nobody can deny being in awe of what Big Ben is able to do in his second year with the Steelers. Nobody can deny the great season that the Seahawks have had nor can they deny the amazing run the Panthers are on.

No matter what the tv ratings will be for the Championship games, these games are still exciting and the desires of the teams still playing is very real.

I am glad the Colts are no longer playing because we do not have to listen to Peyton talk anymore. I am glad that the Bears are no longer playing because we do not have to listen to how their defense ranks amongst the best defenses. I am glad the Patriots are no longer playing because we do not have to listen to how clutch Tom Brady is. Hopefully now we can focus on football.

Nine tips for taking great digital photographs

Introduction

Modern cameras are highly automatic in operation. They have auto focus and auto exposure. The camera will focus on the subject – often identified by a small circle or square at the centre of the viewfinder – and calculate an appropriate exposure by detecting the level of reflected light – usually from the same spot. A slight pressure on the shutter release will activate those two functions, without taking a picture. Further pressure on the shutter release will result in a photo being taken.

1 Take care to Focus and Expose on the Subject of the Image

Imagine you are taking a picture of your girl friend against the background of an interesting harbour. Your girl friend is six feet away while the harbour is around 50 feet away. You position your girl friend carefully – she is important to you – at one side of the picture with an interesting view of the harbour in the distance. Now do you want to focus on the harbour – or your girl friend? Position the square or circle at the centre of the viewfinder over the spot that you want to focus on and correctly expose – take a slight pressure on the shutter release – and keep that pressure while you move the camera to frame the image you want to take – then, and only then, push the shutter release fully down and take the photo.

2 Carefully Compose Your Shot

Before taking the picture take a careful last look through the viewfinder. Check the composition, and particularly that heads and feet are included, and that all faces are visible in anything other the smallest of groups. With the camera taking care of focus and exposure – you have the time to concentrate on getting the composition perfect. Photographic amputation of limbs is unforgivable!

3 Set the Colour Balance Correctly on the Camera

Digital cameras have controls that allow the operator to set the nature of the lighting illuminating the subject. In general they will default to daylight, since shots are likely to be taken outdoors. On this setting, pictures taken indoors under artificial tungsten lighting will look yellow – they will have a yellow cast. Pictures taken under strip lighting will look green. Setting the camera appropriately will produce consistent balanced photographs. Look in the camera manual to see how to set the control – it is very easy. Flash guns produce a light, which is very similar in colour ‘temperature’ to that of daylight.

4 Don’t Expect Too Much from the On Camera Flash

The on camera flash is designed for convenience when shooting a small group of people. It will not illuminate a hall. When watching public events on the television it is somewhat surprising to see members of the audience in the Albert hall take a pocket camera out and shoot a picture with their flash. This is unlikely to be successful. Better to turn the sensitivity of the camera up – say to 800ASA – the ‘film speed’, or sensitivity. This might produce a better result. Do not confuse sensitivity of the camera with shutter speed. They are different.
An on camera flash will illuminate only a short distance – as a guide pick up your cat firmly with two hands by the tail and swing it around at arms length – that is the sort of distance the flash will illuminate!

5 A Tripod is Essential for Long Distance Shots

Most modern digital cameras come with a zoom lens that can take both wide angle and telephoto shots. This is extremely useful. However remember that when the camera is on its furthest telephoto setting, camera shake will become a problem. If you are taking a telephoto shot and the camera chooses a slow to medium shutter speed, the result might be blurred due to the movement of your hands while taking the exposure.
Use a tripod – all wildlife photographers use them. They are a pain to carry but improve quality by orders of magnitude.

6 Fast Moving Subject Require a Fast Shutter Speed

The shutter is that part of the camera which opens briefly to allow light to strike the sensitive surface of the detector to produce an image. Fast moving object require extremely short shutter speeds in order to capture a crisp sharp image. Slower shutter speeds will produce a blur as the object moves.
In general outdoor photography a shutter speed of 1/60th or 1/125th second will be acceptable. In contrast, shooting a formula one car in motion will require shutter speed of say 1/1000th of a second.

7 A little About Depth of Field

In days past, a photographer would measure the level of light at a location with a light meter and then calculate the best combination of shutter speed and aperture to correctly expose the film.
This is now done automatically by the camera. Aperture is the measure of how much light is passing through the lens. The lens has an iris, which can be ’stopped down’ to reduce the amount of light passing through the lens. A fully open lens will pass the greatest amount of light – full aperture – but this also reduces the ‘depth of field’. The depth of field is the band of distance over which the subject is in focus. In 1 above, with full aperture either your girl friend or the harbour is in focus – but not both. By ’stopping down’ the lens – reducing the aperture – both can be brought into focus. But as a consequence the amount of light passing through the lens is reduced. The length of time which the shutter is open will have to be increased to compensate.

8 When taking Landscapes Avoid Putting the Horizon Across the Centre of the Image

Drawing the picture horizon in the middle of the image simply looks naff. It divides the picture in to two and fails to engage the viewer. Best to concentrate on the sky or the foreground. Photograph a setting sun with red sky, or a rainbow with the horizon low in the picture. Or concentrate on the landscape and place the horizon high in the picture.

9 Be Aware of the Effects of Back Lighting

Let us go back to the example given in Hint 1. Imagine that in the picture of your girl friend in front of the harbour, the sun is setting, casting its golden rays across the sea and reflecting on the masts and other metal objects of the harbour with white clouds illuminated red in the dying rays of the sun. An evocative and romantic shot.
Taking the shot with the camera will result in a beautiful background but a black shadow of a girl friend! Now that might be appropriate should you have had a particularly bad day with her and it might correctly reflect the mood. However using the on camera flash to fill in the darkness – to illuminate her face and show her features might be more appropriate on a better day!
