I got a replacement model from B&H and wow is this a world of difference. To begin with, the batch scanning works. It pulls exactly one frame at a time, and does a very good job of it.
I've mainly been using the included Silverfast, so I can only speak to that process for batch scanning.
To start with I hit the Overview button which will do a quick scan and get a count of how many frames are on the strip. It's interesting that it sends the film back and forth 4 times.
- Load the film, press overview.
- Film goes through one slide at a time from beginning to end.
- Film goes backwards from end to beginning, maybe for a recount.
- Film goes through again, beginning to end, this time doing a quick thumbnail scan
- Film goes back from beginning to end to get ready to scan
- First slide does a preview scan.
So if you want to do preview scans of each frame in a strip, you have to hit the Next button and then pre-scan each time.
I dont bother with that since I scan in HDR RAW and then use Negfix8 to apply gamma, etc and do the rest in LR.
My biggest issue with the scanner is that the film goes back and forth so much, but there's no where to put the film. If the roll is curly, great.. it just curls against the side of the machine. If it's flat, then it just kind of smashes up against everything on my desk. I try to roll it up, but then the sharp edges of the strip scratch up against the emulsion. Plus with all the back and forth, there's plenty of time for the film to pick up dust. I shoot b&w mainly, so it's a thing.
I may just put the scanner on a high stool or something so the film can hang off the sides.
The IQ is great.. certainly better than my old Epson v550, but that's not a surprise.
Here's an example from a roll of Delta 100 i just scanned at 5000dpi. Developed in Rodinal, 1+50, 14min.
