The same general procedure can be used to darken as well as lighten portions of an image, again controlling the effect using a layer mask. Hight bit depth GIMP is my primary image editor, and I’ve used the procedure described below for the last couple of years as my “go to” way to modify image tonality. Power lines at noon, before and after tone mapping (aka “shadow recovery”) using high bit depth GIMP’s floating point “Colors/Exposure”.Īfter tone mapping/shadow recovery using GIMP unbounded Levels. The procedure is completely “hand-tunable” using masks and layers, and is as close as you can get to non-destructive image editing using high bit depth GIMP 2.9/2.10.

This step-by-step tutorial shows you how to use GIMP’s unbounded floating point “Colors/Exposure” operation to recover shadow information-that is, add one or more stops of positive exposure compensation to an image’s shadows and midtones-without blowing out or unduly compressing the image highlights. But really these algorithms are special-purpose tone-mapping algorithms, which sometimes work pretty well, and sometimes not so well, depending on the algorithm, the image, and your artistic intentions for the image. Precanned algorithms for accomplishing this task are often referred to as “shadow recovery” algorithms. High bit depth GIMP’s floating point “Colors/Exposure”: much better than Curves for lightening the shadows and midtones of an image without blowing the highlights ¶Ī very common editing problem is how to lighten the shadows and midtones of an image without blowing out the highlights, which problem is very often encountered when dealing with photographs of scenes lit by direct sunlight.

To use these tonings the way they were sampled, be sure to check the “Use Subcolors” option when using these samples with the Sample Colorize filter. This generally means that they were not sampled from a toned B&W image (at least in the traditional sense), but from a color image. In these tonings, for each luminosity value several tones may be defined. a quadtone would have four different colors), but each color only occupies a unique range of luminosity values. Each color can have different shades, and there may be more than one color in the sample (e.g. In these tonings, for each luminosity value only one color is defined. I am currently looking for good examples of any interesting historical tonings. Alternatively, if you see one on the web, please point it out.

If you have such an image, I would appreciate it if you could send me a small digitized copy of the image it need not be any bigger than 300-400 pixels in any dimension (just big enough to contain the full range of color values in the image).

I am also looking for traditionally (wet darkroom) toned images to use in verifying the authenticity of some of these “classic” tones. If you have a particular name in mind send it along in the email message body. If you find a great toned image somewhere or come up with one yourself and you’d like to see it added to this collection, please send me the gradient as prepared as described in the tutorial.

don’t right-click to save the gradient with the text on it, shift-click to save the link target! Alternatively, you can also download the entire collection of samples as a single compressed folder Note that the displayed gradient is not the same as the sample gradient! i.e.

You can download a particular sample by shift-clicking on it’s gradient save it and use it to tone your own images, as described in my tutorial Sampling Toned Images with The GIMP.
