Kenny Rogers, The Gambler and Snow Goose Photography




A million snow geese have been at rest for 30 minutes in the water at Squaw Creek.  Suddenly a lone eagle flies overhead.  A million geese explode into the air as if their life depends on it.  The explosion takes some time because only the geese at the edge have enough room to take off.  As they leave, the edge moves inward until every goose is able to fly.

This is the moment that I've been waiting for.  I fire a 24 shot burst with my Canon 1D Mark IV.  One of the shots will show the water and sky completely filled with geese.  Every shot will be slightly different.  I don't need 24 shots - I'll keep the best one and throw away the others.  

And the night got deathly quiet
And his face lost all expression
He said, "If you're gonna play the game, boy
You gotta learn to play it right

I employed the Spray and Pray strategy for a reason.  I'm using an 800mm lens extended to 1120mm.  It has a maximum aperture of f8.  I have the magnification necessary to show detail in each goose.  Unfortunately, I don't have the depth of field necessary to properly focus on each goose.  I don't have enough light to completely stop the beating wings.  The additional shots increase my odds for success.

You never count your money
When you're sittin' at the table
There'll be time enough for countin'
When the dealin's done

There isn't much time in the field for "chimping".  I do check the histogram and a few shots from time to time, but mostly I rely on my experience and attempt to totally concentrate on what is happening at the moment.  I normally download my images as soon as I return home regardless of how tired I am.  I've worked hard all day and want to see what I got as I back it up.

Every gambler knows
That the secret to survivin'
Is knowin' what to throw away
And knowin' what to keep 

I don't need to keep all 24 shots of a snow goose explosion.  Before I enter any of the images into Lightroom,  I review them twice.  On the first pass, I remove images with obvious problems - overall focus, exposure, framing etc. and put them in a folder titled CULLS.   This decision is quick and easy.  If I started with 1000 images,  I might find 200 to cull.  The second pass is more difficult.  I look for and flag the best shot/shots in each sequence.  If there are a lot of shots in the sequence, I look for the best in each group of 4.  I place the rejected images in a folder titled SECONDS.  If I had 800 images after culling, I may end up placing 600 of them in SECONDS.

I photographed geese at Squaw Creek on March 11th.  I wasn't satisfied with my results.  Instead of finding 6 or even 1 best shots in my 24 exposure bursts, I had 24 shots with exactly the same problem.  They had 99.9 percent of the geese in acceptable focus and .1% of the geese out of focus.  The geese that were out of focus in front of the others were big white blobs in the photos.
 

'Cause every hand's a winner
And every hand's a loser
And the best that you can hope for
Is to die in your sleep"

One of the reasons I decided to return to Squaw Creek the following day was to solve this problem.  I went to sleep thinking about a solution.  I could use a shorter focal length to get more depth of field.  I could focus on the .1% of the front geese and let the back 99.9 become blurred.  I could stop shooting explosions when other geese we in front.

You've got to know when to hold 'em
Know when to fold 'em
Know when to walk away
Know when to run


I returned on March 12th.  The geese were closer to shore.  I used a shorter telephoto for some of the shots.

I waited for shots without geese in front. 


Trying to focus on the geese in front wasn't as easy as it sounds.  The spot focus on my camera wasn't able to distinguish those geese.    I had some success looking for geese that were going to pass in front of the explosion, focusing on them before they were in front and panning with them as they crossed the other geese.
