![]() The more regular the grain the more likely this will happen at some resolution. If raising the scanning frequency helps the images then this, and not digital noise, is the problem. 1200ppi) this type of clumping will go away and you should get a better resolution of the film's grain. If you double the scanning frequency (e.g. ![]() When the grain size gets too close to the scanning frequency (pixel size) you can get a clumped look that doesn't look like grain but isn't digital noise either. There is another issue with scanning where grain can be poorly imaged leaving a blotched look that doesn't look like grain but isn't digital noise either. EPSON Scan's auto expsure adjustments are pretty good, but only when the scanned area does not include any blank film outside of the actual image area. If your scans need any significant exposure/contrast adjustment in an image editor after scanning you may be failing to make proper adjustments in EPSON Scan. I am careful to make proper exposure adjustment in the scanning software to avoid having the actual image data compressed in only a small portion of the scanner's dynamic range. If you indoor pictures are even slightly underexposed you will see more grain in those images than in the outdoor images even when they are on the same roll. When heavily exposed (normal to overexposed) the grain if significantly finer than when underexposed. ![]() Color negative film has rather variable grain size. ![]() Is is possible you are seeing film grain and mistaking it for digital noise. I've never encountered any digital noise using my v700 with the same EPSON Scan software. ![]()
