Hi all, I've recently begun developing my own film and have bought a Epson Perfection v550 to help me digitize my negatives. However, on frames where there are extremely dark areas, the scans appear to be filled with black squares. I thought it may have been a compression issue but the artifacts appear on .jpeg and .tiff scans. If anyone has ever seen anything like these and may know a fix, I'd be grateful. Thanks
