Yes, that's what the exposure controls are for, adjusting the relative
amounts of either R/G/B exposure or ADC offset+gain settings. For the
best quality scans, you typically want to maximize the channel
exposures without clipping, and then correct for color by setting the
Black+White point.
I don't seem to recall the 5400 manual mentioning any "ADC offset+gain
settings". Are these hw controls, and where can I find them? Do you set
the black and white points in the scanner sw or in PS? I use the latter.
I found that after assigning the linear posi profile to a slide scan in
PS, the histograms will shift a bit from those shown in the scanner. If
there are clippings in the PS histograms, I would adjust the Exposure
Controls in the scanner and scan again.
