Brendan,

We store our air photos flat in custom made boxes.  BTW: acid-free boxes are not appropriate for photos.  You have to get the special photo archival boxes (even more expensive).
The boxes we use are plastic.  Very far from acid-free but totally inert with photograph paper.

We have special archival-cardboard boxes (25x25x6 cm) with removable lids (25x6x4cm). However the 23x23 cm photos in the boxes are stored upright, and do indeed warp. Storing them on their sides would be better, but then the lids fall off the boxes (and prevent the boxes sitting flat)
Keeping the photos flat somehow is a good idea.

We group ours by run (with a labelled paper band around each run), and also turn the top photo in each run over so that when handling each run, fingers only come in contact with the backs of the photos, not the front.

Subject: Aerial Photo storage

Hello,

I am asking this on behalf of a colleague.  What is a recommended means of
storing hard-copy aerial photographs?  He has a few hundred.  Someone has
suggested storing them on edge in a filing cabinet in a climate controlled
room, but I thought that may cause them to warp.  Are there any special
factors to consider?

Thank you,
