I figure I will let send out negatives next Monday, March 10, to give people a chance to see this thread and join if they wish.

In keeping with the surprise aspect of it, perhaps we say no posting for two weeks or so, to let people have a chance to print them without the temptation of peeking on APUG to see what others may have done? I'm open to better suggestions or changing the dates

With regards to negative size, I thought that 35mm would exclude the fewest possible APUGgers. So there may be some grain . The negatives are FP4+ developed in D76.
