Hello all, I'm trying to get a "neutral" slide scan out of Vuescan, without success. Here's the problem: even after locking exposure, film base and image color and putting all controls into neutral position (black points at zero, white points at 1, film base color at 1), vuescan is still doing some color processing that apparently increases saturation or something to that effect. The result is weird-looking, perhaps posterized, colors that are quite far from what I see on my slides. Before you tell me to calibrate my monitor etc, take a look at the example I'm attaching. It is a scan of the leader of one of my slide rolls; presumably the clear part should be (more or less pure) white; there is a red strip between the clear and the black part of the leader. On the left are the data from the raw file converted into a jpg via ImageMagick and the picture looks as it should (it matches the slide quite well). On the right is the same picture, but this time the raw data was processed by vuescan into a jpg. Notice in particular that in the vuescan-processed image the red values of the clear leader are _lower_ than the red values of the clear to black transition, which is a physical impossibility (and anyway is not present in the raw scan). Can someone please explain to me why the hell is vuescan inverting the color curve? On a side note, this behaviour seems to have started relatively recently, sometime during the summer, probably with version 8.3.40 or so. Thanks for any insights and suggestions on how to avoid this.
