>>3625698plustek 8100 film holder has frame divisions that almost exactly match the space between frames that leave regular 35mm cameras. so, if you add a second space between half frames, one of them might get partially obscured, like just a tiny bit, by the plastic frame dividers on the film holder. that is if you intend to scan both frames in one pass as if it was a single 35mm frame.
however, the film holder has plenty of sideways space to slide the 6 frame film strip left/right so you can scan 6 half frames in one go, then slide it a bit and scan the other 6 half frames.
I haven't scanned half frame film on my 8100. getting a working half frame camera has proven to be quite difficult.
>>3625707the curves adjustment layer has an AUTO balance button. ALT + LEFT CLICK on it to get a panel with different color balance algorithms. try all the algorithms to see which one gives better results, also try the snap midtones check box on/off (not available on all algorithms). it depends on the particular pic which one will give better results.
you can do that AUTO thing before or after setting up an inversion adjustment layer, but it's better to do it after so you can better see the different algorithm results right away.
