HSL adjustment for 32 bit image

[winfried_z]

Applying an HSL adjustment in HSV mode to an RGB/32 bit image has no effect. Same with beta 2.1.0.1742.

Hi winfried_z,

I'm not having issues here with this, could you show a full screen video perhaps of the workflow used?

Hi Lee,

Thanks for taking care.

I apologize, I am not so familiar with taking screen videos, but I think I can show what I mean by some screenshots.

As a demonstration, I have chosen a picture with a blue sky, and I want to darken the sky while increasing its saturation via HSV.

Original:

RGB/16, HSL/HSV adjustment:

RGB/32, HSL/HSV adjustment:

 

While with RGB/16, the effect is clearly visible, there is no effect with RGB/32.

Hi winfried_z, 

as the gamut is massively different between these two images the adjustments will need to be altered and will not directly translate.

Hi Lee,

I am afraid I was not sufficiently clear in describing my problem. The point is that an HSL/HSV adjustment for a certain colour does nothing when applied to a 32-bit image.

I provide you with two .afphoto files, one in RGB/16, the other in RGB/32 format, both containing the same pixel layer and and the same HSL shift adjustment layer. You can see that with the RGB/32 file, the HSL adjustment has no effect.

Hi Winfried, 

The same adjustment might not work, however a little tweak shows that the HSV is working correctly.

Hi Lee,

Thanks for your patience, but unfortunately, for me this does not work, see below.

Would it be possible to save this project as it is and post that.
