From the mailbag: Jim, I’ve been told that the Finest Detail feature applies to vector art/line art only. That it has no effect on bitmapped images at all. I gather your result contradicts that assertion? I’ve never done systematic testing of it. My tests with V- and H-stripes test images showed clearly (a few years back) that… [Read More]
Focusing, part 3
OK, so your autofocus works under controlled conditions, but you’re still getting some misfocused pictures. The camera thinks it’s focusing properly, but it’s not focusing on what you want.

The 2880/1440 resolution setting tells the halftoning algorithm not to use any but the smallest… [Read More]
