I finally figured out how to fix “keystoning” in my photos during the whole export/optimizing process in Macromedia Fireworks (which I use over Photoshop mostly because it isn’t quite the memory hog). So, I went through and fixed up several of the photos in the Cascadia photo gallery. The difference shouldn’t be all that noticeable — after all, the goal is just to fix something that we see but that cameras exaggerate — but it definitely soothes my perfectionism.
(BTW, the full-size pictures, but not the thumbnails, were fixed.)
