I just got back from teaching a photography class at the extension office in Webster City. It's a two part class on exposure, which will continue next Saturday. So, I've spent two hours discussing apertures, shutter speeds and ISO. Kim and I are having a date night tonight, so I needed to come up with a picture quickly before we leave. Claire said I could take a picture of the book she was reading, Oh Say Can You Say, by Dr. Seuss.
