I have a Minolta Dimage Scan Multi Pro, which Iove, and have mainly used to scan chromes and black and white negatives, with Vuescan. Recently I scanned 35mm Portra negatives, well-exposed, and had a hard time getting good color. I've been using Vuescan for years, and feel I have a good grasp of color adjustments. I scanned the same Portra negatives with Vuescan and a Canoscan 9000F, and it was much easier to get the color where I wanted it; using same Vuescan app and color controls. Apparently the Minolta scanner has a dynamic range of 4.8; can't find that for the Canoscan, but I assume it's not higher than 4.8. The Minolta is Firewire 400; I can't get it to work with my current Mac, even with adapter, so I use an older Mac Mini for Minolta scans. Anyone have any ideas why color adjustments in Vuescan would work much better with the Canoscan?
