If you have maya, you could probably do this by plugging out color of a file texture node into a rgb to hsv node or rgb remap node (forget which one) and then plug output saturation into r g and b color channels of a material applied to a simple plane. You could make a scene with the shader network set up and select the…
Well, it's not non-destructive, but I think I've found a way that works pretty well in Photoshop. * Duplicate the layer that you want to visualize the saturation of. * Change the image mode to Lab color (Image->Mode->Lab Color.) Don't flatten the image when it asks you. * In the channels palette click the Lightness…
In Krita: make two clone layers of the image or the top level group you want to analyze. Add a Desaturate filter mask (Rec. 709) to the bottom one and set the top one to Difference blending mode. Add a Desaturate filter layer on top of them both, then a Brightness/Contrast filter layer that you can adjust to more easily…
I can't get 3CH to work. It opens for a quarter of a second before closing itself. I'm on the latest version of windows 10. I have attempted this in both admin mode and compatibility mode. I even downloaded the latest .net framework. What gives?
as a kind of side note: I've found that using the Black & White filter in photoshop gives different results from simply sliding the hue/saturation slider down to gray. I was told B&W filter was more accurate to see the values but I don't exactly know the math behind the different functions.
Some cool stuff in this thread. I'm also into the approach kwyjibo described, which is to "program" that the saturation should become the RGB values. A way to do that can be through ImageMagick, it's a command line application that can convert images and do several filters, such as a "FX" filter where you can write…
