Kevs ... thanks. I should add that the negatives in the original post is only about half of the roll. After that second strip of overexposure, there's one more (which wasn't there as I was using it to scan), and then the frames are fine once again. I will go check the battery right now though, it looked fine last I checked. Film speed - no way, it shows me the DX reading for the ISO and it's always correct. FP4 comes in at 125, HP5 at 400, Portra at 160 or 400, Gold and Superia at 200, etc.
