This image of a ring-billed gull seemed perfect for the theme of depth of field. He posed for me near a pond at Lincoln Park Zoo.

Depth of Field
If it seems as though I'm posting a lot of bird photos lately, it's because Jon was on spring break, and I tagged along on some of his day trips as he stalked birds all over northern Illinois.

Deep into the depth of field, or deep into the fields
My DBF brought home some lovely flowers to celebrate our 100 month anniversary last week (awwwwwww!) A few days after, several lilies burst into bloom in the vase, allowing me to experiment with different aperture values, thus controlling the depth of field.
Shutter speed: 1/15 (wow! still fairly clear...) f/5.6 (lowest I could get with this lens, and the distance I had to be to remain in focus), ISO 800 (75 watt kitchen light bulb), focal length: 154mm (me, standing on a kitchen chair).

Zoom zoom
A line of Harley Davidsons, parked at a hotel in Colorado, await their riders.
The camera data on this puzzles me a bit: 1/40, f/8, 109mm, ISO 800. This was fairly early in the morning, on the shady side of the building, thus the high ISO. For the depth of field in this image, I would have expected a lower aperture #. Must be the longer focal length? I don't recall what mode I shot this, so I can't claim credit for the exposure. Probably Tv?
