I noticed some banding after scanning a recent roll of film. I do not see the lines on the film but the scanner is picking it up and I'm not sure if its the scanner, lab, or my film back. Any thoughts? Yes there are newton rings, i need to let the film flatten for a bit before re scanning. Untitled by Shutter_Inc., on Flickr its Kodak Ektar. I had to have it pushed two stops because I thought it was my film back with 400 tri x. I turned it B&W and messed with contrast to get the bands to stand out.
