Ha! rainphot, a moment after I posted my thread, I knew that somebody would say "you think that's cool, you should see large format"! You are, of course, right. I feel I do have some insight, I sometimes shoot 6x17cm panoramics with my Linhof Technorama, although I don't have an enlarger big enough to do optical printing, but the 120 megapixel scans from colour slide film are impressive (the SA 90/5.6 XL lens is really quite special).

For my kind of work, however, 6x7cm works well most of the time... I have not yet worked up the patience (or funds) to shoot one sheet at a time :-) But one day...
