Nowadays SilverFast will always acquire the maximum dynamic range (raw scan) available from the hardware during the capture phase. My question is, does this actually make any change to the data captured by the scanner? Of course you’re not throwing away data because there is no data above or below the minimum / maximum brightness ”The image data is spread to cover the histogram in full”
#Silverfast 8.8 black and white manual
It’s on page 14 of the manual ( which I’ve never read ) ( ) For colour SF samples down from 48 bit to 24 bit for the JPEG anyway, so I’m guessing there’s room.īut there is a representative from SilverFast on here ( ) you might want to message them directly and get a definitive answer. I don’t know if it throws away data but given that I scan to JPEG and don’t normally post process it’s never been something that bias bothered me. I have always moved the dark and light points to those edges before scanning. I use Silverfast all the time and for older slides the histogram tends to have an edge set back from either end (as you describe). What's the best practice for best quality? If it matters, I'm using Silverfast AI Studio 9 with an Epson V850 Pro. My question is, does this actually make any change to the data captured by the scanner? Or is it effectively doing the same scan it would do regardless of settings, and then applying post-processing to the result, which I could just as well do in Photoshop afterwards with probably more flexibility? Am I actually throwing away data by doing this adjustment as part of the scanning process?Īnd similarly, what other adjustments (exposure, for example) are beneficial to do before running the scan, if any? It occurred to me that the data captured by the scanner might be basically hardware-limited, and a flat un-adjusted scan might capture the most data - which would be best, as long as I'm willing to take the time to post-process elsewhere later.
If I have a relatively low dynamic range negative, so the histogram is mostly clustered in the middle, I can move the histogram end points to set the black point and white point before I do the scan, and that looks like what I would expect in the preview (and pretty much in the final scan). Quick question on Silverfast best practices (and no, I'm not looking for "use Vuescan" :-), been there.).
