After learning a few tips at the excellent UUG meeting on thursday, I thought many of you might be interested in this tip on sharpening pictures with less noise. If you decompose the picture into the HSV layers as he described last night, if you click on the "value" layer, you can run a sharpen or unsharpen mask operation on this layer only, without affecting the colors or saturation. This will sharpen your image with much less noise than you would get sharpening the usual way. Just recompose the image as we did last night. You can do this operation as well as fixing the saturation curve before recompositing.
Also I found a neat script to help fix those times when the sky is over-exposed and white, rather than a nice vivid blue. It doesn't always work out, but sometimes it works rather well: http://www.farcrydesign.com/GIMP/BlueSkyGradient.html http://www.farcrydesign.com/GIMP/BlueSkyClouds.html -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
