Hello! I've been using the 4990 for 4x5 with good results. I've picked up an 8x10 to try my hand at some alternative processes. I imagine that I may end up with some 8x10s that I'll want to enlarge.
I've read that the 4990 can scan 8x10 and some have indicated excellenet scans in the 2x ballpark, or even larger.
I've read that some folks feel that there is a sweet spot in a scanner, as well. Does the 4990 scan an entire 8x10 equally well or is there a sweet spot, so that parts of the negative would not be scanned well? Best regards.
