    Will Scanning at 48bit with no adjustments work?
    by Fazools
    I use silverfast AI studio, and love it. However I have about 10 more photo albums to scan in 2 weeks, and they are from the 1940s and 50s.

    Reconsidering 16 bit

    Personal Experience
    by Ed_L
    I have a 4 x 5 neg from around 1924 that I scanned in both 8 bit, and 16 bit per channel. The scan needed a lot of tonal adjustment, due to the condition of the neg. I expected to see a pretty good difference in the histograms for the two files after making 15 - 20 tonal adjustments (some pretty steep)....
