Good grief, its funny to see that again. I can remember doing it! Looks like a nice job, I probably have the unreduced SAC development image (I used to work in 1024 square/16 mill colours) somewhere on file. Let me know if you need it, it'll be enormous, and I don't have broadband, so I expect the easiest way to make it available is to upload it to the web.
Let me know if you want it?
