The area in which this cache is hidden looks a lot like the software I spend a lot of time working with, not far from here.
Spreadsheet Stash is a small cache, not quite micro, but you won't fit much in it. It contains the second piece of the photo clue to A Picture's worth a Thousand Degrees, as well as a few small swaps. No need to swap anything if you're just taking a bit of photo.
Be careful you're not observed replacing the cache.
