This is a bonus photo for this week, as I won’t be working on a long form blog post.
This is an HDR shot from my backyard. My wife and I had just gone for a canoe ride on the river here and I loved the sunset, so when we were finished I grabbed my camera, tripod, and set out to try an HDR. I took 11 exposures ranging from 1/400 to 1/8000 at f/3.5 and ISO 400.
Shot with Canon 40D with EF28-80mm f/3.5-5.6 USM set at 28mm. I used the auto-bracketing feature multiple times. HDR put together in Photomatix with some minor editing in Photoshop.
Older SLR (single lens reflex) cameras, pre-digital info screen, had aperture adjustment on the lens itself. The image shows an example from my Minolta X-700 with a 50mm f/1.7 lens, made in 1983. This camera does, however, have a full auto setting, so that it can adjust the aperture for you. Unfortunately, you cannot tell what it is adjusting to without the digital screen that the somewhat more modern film Canon Rebels had.
