Our scans for previously undeveloped film, result in an image that is 8 inches by 300 DPI on the short dimension or your frame. Example — a 35mm frame would be 8 x 12 inches at 300 DPI — a 110 frame would be 8 x 10 inches at 300 DPI.
Because we are so often dealing with very low contrast negatives the scans are done at a high bit rate, then adjusted for brightness and contrast before down converting to 8 bit JPEGs. This creates a smoother grain scale than would be possible had the images been adjusted for brightness and contrast at 8 bit.
Our scans for most previously developed film is 12 inches at 300 DPI on the short dimension of your frame.
