Brightness, contrast and gammacorrection are concerned with the colors of the image. See chapter 11 of my FAQ. Dusting-off is concerned with obscured pixels. Basically there are two problems with dusting off: 1- Where is the dust 2- You cannot see what is under the dust 1 is (partly) solved by the IR-scan. Ideally, the IR scan should give a black/white image with only the dust on it. This is never the case: some dust is grey, some of the other colors bleed through to the IR-channel. I still got some work to do here. You can "cut-out" the dust and make holes in the image. 2 is solved by interpolating the pixels around the hole. Andreas used a simple interpolation method that works well for small holes. I renamed his filter to "fill holes" under GIMP. You can test it without a coolscan: - take an image - add an alpha-channel - cut a small strip away - start filters/enhance/fill holes (of course you need to install the filter first) ljm -- (c) ljm @ xs4all . nl.
