This is asked out of sheer curiosity, Bill and not out of devilment but I think it is a "given" that when scanning to demonstrate a possible negative problem it is important to ensure that the scanner operates at the minimum level required to correctly replicate the negative, so in terms of said minimum level is there a list of scanners that meet this level?
For instance, I had a thread on a negative that needed grade 5 and still seemed to fall short in terms of a good print but I wouldn't begin to know if my printer/scanner(HP 2510) can scan negatives sufficiently to demonstrate the problem( real or imagined as the case may be)
I appreciate it is difficult to know where to draw the line and I have no desire to add a hybrid section to FADU but a certain minimum level of knowledge of scanning and scanners may be needed to utilise the permission given to us by FADU to utilise scanning for the purposes of analysis of negative problems.
In the "old days", pre-internet we'd have met face to face and the actual negative would have been on show for discussion but such a straightforward method is not open to us.
Some education may be required which entails discussion of scanning and scanners simply as a means to an analogue end
