Steven Woody wrote: when playing with level or curves, did you guys adjust each channel alone or the overall combined value? I'm no expert, but I usually start with the easiest operation and work my way to the more difficult. I'll try Auto-Levels first, adjusting the brightness with the middle triangle. If I don't like that, which is probable with a dark image, I'll undo it and adjust the white and black points on the combined channel. If that leaves a color cast, I'll adjust individual channels. Wish I knew how to work the curves. Any recommend a good tutorial? Andrew Robinson ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Any recommend a good tutorial? i've not worked that one out at all, have no idea what it's supposed to do. my first step is pretty much like yours -try the simplest method first which in my case would be to adjust brightness and contrast and then to look at colour balance, both under the layers/colours menu. i then may use the levels tool which allows you adjust alpha and the rgb channels in parts of the image rather than the whole image. sammi ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

There is no single method that works perfectly in all cases, but you can try Image-Layers-Colors-Levels or ...-Curves. In the Levels dialog, try moving the left handle (the black one) to the right. Try moving the middle one as well. The preview will allow you to see what happens and should help you to find the best values for correcting your pictures. The Auto button can give interesting results, but can also introduce color casts so maybe you should experiment first with manual adjustments.

Sven ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user I sometimes use a copy of the image added to the original. Test the following (in Gimp 2.2.8 anyhow) Start Gimp. Open the picture which you want to lighten. Make a copy (right klick on the image - Layer - Duplicate layer) In the layer window: Layers Mode set to Screen instead of Normal. That lightens the image some. Just redo the steps above for even brighter images. Its a fast way to brighten things up without having to play with values. /Rikard ___ Gimp-user mailing list Gimp-user@lists.xcf.berkeley.edu http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
