Sunrise, Gibraltar Island. OSU photo workshop.

This sunrise photo was taken at last year’s outdoor photography workshop  hosted by OSU’s Stone Laboratory on Gibraltar Island. The workshop this year starts tomorrow.

With a 24mm focal length, an aperture of f/11, and the lens focused at a distance of seven feet (the hyperfocal distance), the depth of field is 3.5 feet to infinity. I would have preferred f/16 but the 1/8 second shutter speed would have been too slow for the motion of the water. If I had it to do over again, I would have boosted the ISO to 200, changed the aperture to f/16, and left the shutter speed at 1/15 second. That would give me the same exposure but more depth of field.

The meter reading was based on the sky to the left of the sun (and the sun was not in the frame when the sky was metered).  This left the foreground quite dark. When the RAW file was processed with Adobe Camera Raw, the foreground was lightened with the “Shadows” slider.

Photo Data: Canon 5D Mark III. Canon EF24-105mm f/4L IS USM lens at 24 mm. Gitzo Mountaineer tripod. 1/15 sec, f/11,  ISO 100.
