From this forum thread:
https://www.cinelerra-gg.org/forum/help-video/problem-with-colour3way/ After the patch to make Color3way work in float, even with values above the range (0 - 1.0f), this problem occurs: "If I move the Shadows Value slider to the left, by the time it reaches 0.006 the image is almost totally black, which makes it totally useless." and: "I confirm the problem. The color wheel also behaves the same way, while the saturation slider works normally. Midtone and Highlight work normally." The applicated HDR patches can be seen here: https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=commitdiff;h=3cd... I've tried a few builds/tests. The patches for Overlays and for Histogram plugin seem to work normally. Only the patch for Color3way causes a problem. This problem occurs only for shadows, which is strange because the patch only alters the white boundary and leaves the black boundary unchanged. I tried to read the plugin code but I am not able to understand the problem. Does anyone understand anything about it? For now you could exclude the Color3way patch but put the other two back in. PS: Using the overlays in the patchbay seems to me that the PorterDuff do not work. This does not depend on the patch because I have the same behavior even with the old appimages without the patch...
