On a hunch, I did a Google search on “photo synthesis” and “gallery”.

It got back 815 results, and it looks like most of them had to do with museum-like photography exhibitions. Which tells me that “Photo Synthesis” as a title for some artsy-fartsy collection of snapshots is way overused.

Despite the edgy-sounding co-mingling of those words, aspiring artistes should keep in mind that, when you get down to it, at root they refer to watching grass grow. Not the most scintillating of imagery.
