I stumbled onto this at Reddit today. I DL'd the hole dropbox. Wish the photos had some kind of element to give scale, but they seem to be all at the same relative frame size.
Well I have reviewed ever one of his pictures...s7_a1 was out of place because he capitalized the "S" making it S7_a1 which was AA#2 powder...
BTW great picture file, It will be useful and I hope he continues the project.
