Im curious. I just read this whole thread and still have a couple questions for you.
what purpose does archival aerial photography serve? is it a surveying thing? geological? or am I completely off base and lacking any comprehension of what your business is? I understood you as saying you also do enlarging for people. but Im just very curious about the aerial part... very intriguing. and congratulations on the constant business and I hope things continue to go wonderfully for you.
