No, wait, because this thing goes through photos so quickly we had already scanned hundreds of pictures. Oops.
Still, it wasn't a big deal, because the scans were rather good and the "corrected" images ... were hit and miss. Many were still discolored; a few were somehow worse. Basically, the software is no match for good Photoshop skills. So if you were hoping for thousands of print-quality images right out of the box (so to speak), you'll be disappointed. It's unlikely you were going to print that many images anyway. If you were planning to throw stuff up on Facebook, you're probably fine, and you can share straight from the program -- though my mother and I opted not to upload the thousands of scans we made yet, because we're not monsters who overload people's feeds. (We did choose to have it back up everything to Google Photos, however.)
Most of the photos in my mother's collection were pretty standard 4-x-6 snapshots, but there was a hodgepodge of sizes and textures to worry about, all with unique challenges. Matte photos fared the best while glossy prints had a tendency to stick to one another, requiring me to open up the machine and pull them apart. This is easy to do: The FF-640 is designed to split open so you can remove trapped documents or clean the rollers inside.
Polaroids presented a problem until I fiddled with the settings on the scanner itself. (My mother later found they worked best in a small stack.) But the biggest surprise came from an old photo booth picture of my great-aunt, which was either developed with silver nitrate or a close relative thereof. Its cardboard frame carried a date of 1945. I was feeling pretty confident about the FastFoto at this point, so I took the photo out of the frame and dropped it in the scanner. It went through smoothly, with no damage to the picture (whew). I opened the file, and it was perfect. The scan even smoothed out an errant fingerprint on the original document.
But given the FastFoto's blistering speeds, I wouldn't recommend putting fragile photos in it by themselves. Epson actually provides a special transparent sleeve for such documents, but in practice I found it kind of hit or miss too. Sometimes I would get a clean image, but occasionally a ripple from the plastic made its way into the file. These might be best left to a flatbed scanner, which the FF-640 is not.
It wasn't long before we had cleared out most of my mother's little filing cabinet, several manila envelopes and other assorted ephemera from not only my childhood but also my mother's own youth and that of her seven siblings. At this point I decided to bow out and leave my mother to it, confident that the FF-640 was simple enough for her to use on her own. She wrapped up not long after I left, which I could have guessed from all the pictures she's been posting on Facebook. Where she used to repost the same shots over and over, she now has enough original material for #TBT to ensure I'll be blushing at old photos of myself for the next decade.
