My prints have just arrived back from Peak Imaging, and I have two frames with white spots on the negs - I've attached a scan for details. Both similar spots, the second neg less so, and similar pattern in the same sort of place on the frame. I can only think that somehow light has got into the back of the camera, and gone through some of the spots on the backing paper. Anyone got a 120 Portra backing paper to hand to compare with? I know that the numbers are a bar steward to see througfh the red windows (camera is a Moskva 4), I wonder if it's a reflection of light that's got in round the window, but other views welcomed!
