Lowering luminosity with an HSL adjustment layer on pale colored pixels might saturate the pixels, instead of making them darker. This is true where any of the RGB values is maxed out, ie at 255. I discovered this with a sky that was slightly blown out. The example image shows blown out reflections of spotlights on the ice in a hockey game. A slight adjustment of luminosity makes the border of the blown out area saturate, in RGB/CMYK base colors. This can be reproduced by purposely filling areas of a pixel layer with colors like 255 255 249 and then applying HSL and lower the luminosity. If you push down brightness far in a brightness/contrast adjustment layer, you will get a similar effect. I consider this a seriuos bug. Lots of source photos have blown out details by necessity, like the hockey rink spotlight reflections in the image. Combine it with jpeg blocking and the luminosity slider is unusable.

Please check "Custom Levels" and "Brightness/Contrast" layers on both Photoshop and Affinity to see the difference. Levels applied in Photoshop only to Red, Green and Blue channels (not to Master) are not present in Affinity Photo. Brightness/Contrast applied in Photoshop (with the "Legacy" checkbox on) have different values and a completely different look. custom_levels.psd
