I played a bit with Adobe Photoshop Express in Windows phone and found a useful adjustment that increases the gain in deep shadow portions, while at the same time keeps *untouched* the already bright areas (above a certain predefined level).
Here is a sample: (original image) http://www.secarica.ro/temp/test_808_original.jpg (shadow increase to 100%) http://www.secarica.ro/temp/test_808_photoshop_express_shadow_100.jpg For the above image, the processing time when saving is about 11 seconds (on a 1.2GHz quad core Windows phone). The application's adjustment looks like this http://www.secarica.ro/temp/wp_ss_20170407_0003.png I tried in GIMP various filters, effects, scripts, curves, fake HDR etc. but with either I played with, there was always a slight change also in the bright portions of the image. What adjustment can be used to obtain the exact same result by using GIMP ?
