I am looking for guidance on how to correct the color and brightness on photos taken with a non-digital SLR. Some are only available on negatives and slides, some are on Kodak Picture CD's. I have saved them as JPG's, but none of the editing programs or tutorials are giving me the results I want. I have been frustrated trying to adjust RGB, brightness, saturation, contrast, gamma, etc. I thought I might make some progress with histogram equalization and white balance, but the results are grainy. When I first took up photography as a hobby in the 1970's I bought some basic color filters to adjust lighting conditions to daylight or tungsten film. I also remember reading about color correction filters. I think the theory was that there were three color groups, red green and blue, and within each group filters (glass or plastic sheets) would vary in density from 005 (very light) to 060 (very intense). By using various combinations of these filters, one could duplicate the effects of my basic filters, but a whole lot more as well. Mistakes with color on ANY picture could be fixed by just combining the right densities of the right colors (e.g. red CC5R + CC40G). Is there any software that simulates holding up color filters in front of a photo? Is it possible to remove graininess after brightening a dark photo? Two examples of what I want to do are shown at http://user.mc.net/~aevarga/tests/photos/photos.htm In the first example I want to restore the sky colors shown in the left picture to roughly the colors available in the right picture. The one on the left is too red because the sun was still up; even with stepping down the aperture it was probably overexposed. I would also like to restore a little of the foreground. In the second example I want to brighten the overall picture, as well as restore the correct facial tones and sash color of gold/yellow. The faces acquire noise (?) when I brighten the picture, and I can't seem to get the yellow correct. Since this is a hobby and I'm not retired, I have neither the money nor the time for Adobe Photoshop. I have been experimenting with IrfanView and Helicon Filters. Can anyone recommend software for color correction with presets, as opposed to airbrush techniques, removing red-eye or creating fancy borders? Also, are there any good web tutorials or books on color restoration which are software-independent?
