I have a photo with poor quality and lighting that needs to go in a print newsletter. There is some lighting issues, and a blue-ish color in part of the image. I'd like to fix the image using GIMP.
My first question is what is this problem called? It looks like everyone is glowing. The blue color on the man in the front's lab coat is not accurate.
My second question is how to I correct it? I've attempted a few things so far that were not successful:
- Create a new layer, invert the colors, and desaturate the colors, then set the layer mode to overlay. This is the only technique I have experience with, but the results were not very good.
- Use the burn tool on the mask layer in #1. This only marginally improved the situation
- Tried the suite of automated tools under the color menu--these didn't make any substantial improvements
- Tried to use the clone tool on the blue lab coat on the man in front. The result made it look like his lab coat was enchanted, adding +1 to his magic resistance but not improving the image. I could not figure out how to deal with that area of the image.
This exasperated my current photo editing skills. Is there another approach I can take, or is it simply that the image is too poor?
