Another trip to Palo Alto, and another non-work expedition. I went down to the Monterey Bay Aquarium with Ctein and Paula and about 25 pounds of camera equipment. Which wasn't enough.
These are very preliminary results, but I wanted to show off a few of them. They'll probably end up over in "real photos" when I get to work them over with the good tools.
The more experience I have with Gimp (version 2.2), the less I like it. There isn't a bicubic interpolation function I can find, and there isn't a way to make the color of a selected spot in the image neutral. And the unsharp mask tool is weird, but that may be just unfamiliarity.
