Note how sometimes in a photo, parts are not detailed. You adjust contrast and brightness, but other parts becomes too bright or fainted out. The solution, is to take several photos using different exposures, and then combine these photos into one. These techniques are called: Tone mapping, High dynamic range image. The result is a colored image with high detail everywhere, which may make the image looking artificial, but desirable for its detailed illustrative effect.
Problem: What systematic technique to use to turn the first image into the second image?
The first image is from Wikipedia. The second is found on the net. Apparently, someone made the tone better, but also cropped the image, and censored the nipple.
Look at the second image, and note the color of the wall, the girl's skin color, the blue-colored clothing on the right, and how the girl's calf is clearly see-thru.
I'm using GIMP and tried various color filters and adjustments, but couldn't do it after trying the various parameters and filters. The one technique is to select parts and apply color changes, but i'm seeking solutions that apply to the whole image. (unless, a image pro specializing in color enhancing tells me the only solution is to edit parts of the image separately.)
I think a combination of the following will do it: Filters:Colors:Retinex, Layers:Colors:Curves, Filters:Enhance:Unshap Mask.
Note: The picture is Flaming June by Frederic Leighton.
