LeviFiction Posted April 10, 2020 Posted April 10, 2020 (edited) Hello, I'm confused about how the HSL adjustment actually works. I get the basics. I own several photo editing software and have used HSL adjustment before. And Affinity's HSL adjustment works exactly as I expect it to when it's set on the Master Channel. Moving the Luminosity Shift to -100% blackens the image. The problem that I run into is that selecting any of the color swatches to narrow the effect, don't work like I expect. Take for example this image : https://www.pexels.com/photo/orange-lighthouse-1660995/ If I highlight the blue swatch so that it selects hues 225-255 with fall-offs at 195 and 285 and I move the Luminosity shift I expect these colors to start moving toward black. Instead they just get more greyscale. The luminosity is barely touched. It's a great effect but why does narrowing the targeted pixels by hue change the function of the luminosity slider so drastically? It's not what I expected to happen at all. Can anyone help me to understand how this works? Edited April 10, 2020 by LeviFiction Quote
LeviFiction Posted April 10, 2020 Author Posted April 10, 2020 Thank you, that makes some sense. But I'm still confused, while I can see and accept that it's not just selecting all pixels of a certain hue and is in fact working on RGB channels, why doesn't the blue channel go completely black at -100? Instead they seem to be coming into line with the Red channel? Quote
