I'm currently thinking of switching my default Konica-Minolta scanner software to one of those third party system, primarily because I find that the default program seems to want to do strange things on the autoexposure function. My black and white photo scans are usually lacking in dynamic range. While testing out Vuescan this week I realised that I was able to adjust the scan so that I get maximum details out of it and then adjusting the exposure in something like Lightroom in order to have a balance between detail and exposure. So excuse the slightly darker looking photos in black and white.
At the same time I'm thinking of getting some IT8 targets to calibrate my digital camera and photo scanner. I think some of the colour photos just don't look right in terms of colour, even on a calibrated monitor. So that's the next project coming up... I have already found a reasonable priced vendor for the targets. URL below.
