I am new to this board and new to scanning film negatives. I have an Epson 4990 Pro and am using Silverfaast AI Studio as my software. I have scanned about 20 6x12cm Noblex 150 panoramic negatives previously with this scanner and Silverfast, with what seems to be excellent results. Today however, I notice that my 6x12 negative scans show a moire pattern in the dark brick of the building I photographed in the negative. I am using the manufacturer supplied negative holder. I do not think this moire has shown up in the other negatives I scanned, and this is confusing to me. Can anyone give me advice on how to deal with this problem? Is it a scanner problem, can it be fixed in Photoshop? Thanks in advance for all responses. If I find out any additional info outside of the board, I will post what I find.
