Here's an update: I had Recuva do a deep scan and when it finished (hours later), it had "found" more than 58,000 files. Excitedly, I went through the list of files that were identified as in "excellent" (recoverable) condition (unfortunately most were listed as in "poor" condition); I marked the ones I wanted, which were not all of my photos (not nearly), but at least it was something, and hit the recover button. I'd selected well over 100 files, but Recuva reported that it was unable to find all but six (and those six were useless). It found them in the deep scan and listed them, but was unable to find them for recovery. That was very disappointing. I'm going to find a professional to examine my drive.
