I did my first VDB last night, and it sat for 2.5 hours before developing. Unfortunately I didnt look closely enough at it when I pulled it from the frame and stuck it in a dark box, so I couldnt say if anything happened between then and development. I will say that for my first VDB I was pretty impressed with my skill. It looked like my exposure was pretty good for the first tme (10 minutes in sun), and I loved the medium brown color. Until, of course, it dried, and now its way too dark and I dont care for the color nearly as much either. I guess you havent seen drydown until you've seen VDB drydown, huh? Live and learn, it certainly could have been much worse.
Could I stick it back in the fix to lighten it, if I were so inclined? (and I'm not sure I am...)
