This
weeks Sunday Snapshot Tech is another frame from a recent photo shoot on the
shores of Long boat Key, Florida.
This Gulf coastline is located near Bradenton, about 40 miles South of
Tampa. As a family we have been
visiting here for 20 plus years. Anne and me took a stroll after enjoying a fine
meal in Sarasota; the sun dipped below the horizon, the washing and rolling of
the agitated surf; after all these years, each time we visit, it is like the
first.

Photo Tech:
My
70-200mm is already mounted to the tripod, the spiked feet extended to grab
hold of the damp sand – I spend a few moments scanning the view – the horizon –
for a composition.
After
I pick my location it is crucial the horizon is straight through the
viewfinder; we know trying to “straighten” an image file in post production
will interfere – alter- the quality.
So, we always strive to capture the scene the best we can from behind
the viewfinder.
The
lens was zoomed to 70mm, the aperture closed-down to f/20, for deep depth of
field, (DoF), and most unusual, an 800 ISO value, not to help capture the scene
in low light, but as an experiment to add digital noise, (film-grain, if you
will), to the picture. I triggered
the shutter via an electronic device to help reduce camera shake during the
slow shutter speed required to capture this image. (A big thank you to my wife, Anne, for capturing me at work; photo of me snapped about 20 minutes before the featured image discussed in this blog entry was captured.)
Here is the complete list of specs for the above image file:
ISO
800
F/20
Speed
= ¼ second
+2/3
exposure compensation
Post Production:
The
color image file was adjusted for brightness; a small amount of dodge &
burn was applied to the background waves, (I left the drift wood as is). The BW conversion included a modified
blue filter and Cyanotype color dip.
For effect, I added the burnt frame. If printed, the digital burnt frame will be replaced for
either a real burnt edge print or none at all.
The
final image shows softness due in part to the slow shutter speed in combination
with a little digital noise from using ISO 800. I hope you like this image and be sure to try this type of shot
next time you are on the beach – contact me with your questions. Have a great day!
Best
regards,
Lance
