Curves and how control the colors

Great! Thank you RawConvert!

I use one tone curve, Lab-L, along with the Exposure and Black sliders. Haven’t noticed colors going wacko. Color adjustments I do with Lab-b and -a, the HSV equalizer, and occasionally Lab CL and CC. I’m fortunate enough to have a wide-gamut monitor that shows most of Adobe RGB, and I use Adobe RGB as my RT working color space.

Since RT is after all a raw developer, I export an Adobe RGB .tif and finish in Picture Window Pro. PWP has a good color-managing print system based on the lcms engine.

Are there flaws in my minimalist procedure?

For examples, converted in PWP to sRGB for the Web, see images tagged Raw Therapee at

@RTCharles always nice to hear a success story :slight_smile:

That’s where the orange tones come in. It’s in the first picture by the author. I would enhance the shadows for the saturation channel. On the curve. The closer to the more saturated values, the darker it gets.
If there’s a program somewhere that has both hsl and hsv tools, then for hsl I’d loosen the saturation and for hsv I’d raise it so it stays the same as it was before processing.
Well, for the orange tones for sure. You can also mask the hues.
Just crushing lights in shades of orange is definitely not it. Not at all.
hsl vs. hsv. S in hsl vs S in hsv.
