i think you meant 1 isn't enough ?
it's enough for me, because i sometimes
make negatives by hand and assemble them &c
and once the print is made ... i make another ..
even with the materials in front of me, another can't be made
the problem with closed editions, is there will always be an 11th person , or a 12th &c
that is why i don't bother with editions, they are almost a joke ( IMNSHO ), just make as many as you want
and number every one, if you want to number them ..
with editions people make up their own rules " no, that edition was for 8x10 images, this group is 20x24, its a new edition"
sort of thing .. what's the point ?
good luck with your sales
