IPv6 Posted July 7, 2018 Share Posted July 7, 2018 (edited) Thanks for great alternative to Photoshop, just switched and feel VERY impressed. AP (Affinity Photo) almost complete replacement of PH for my needs. There is one color-correction-related feature is missing, though... as usual, but... this is feature requests section, right? Both AF and Photoshop can work in LAB mode, but LAB support is different in some areas - and PH way feels better in some cases. The most notable case - HSV correction layer. In Photoshop, its meaning is different for Lab documents, it work in some "LAB Logic", where "Hue" is angle between vector (A,B) and arbitrary axis on imaginable color wheel, "Saturation" is length of (A,B) vector and Lightnes - is pure Lab lightness, after all. It`s easy to notice - if you disable all channels except L and try to shift Hue (looking at document with only L channel enabled) - you will see NO difference in Photoshop. Hue completely separated from lightness. And you will see huge changes in AP (with Lab-converted document and A/B channels off). So in AP hue still contribute to L-channel a lot, even in Lab color model. And to sum this up - PH way really gives better results for some styles (anime style, to be honest). Imho, perfect solution should be like this (and this is my feature request) - HSV correction layer already has a checkbox "HSL", which change the way values are evaluated. Just swap it with dropdown menu and add another option - "LAB interpretation", which will give recalculations like in LAB documents in PH. This may easily work even in RGB documents! Of cource, RGB->LAB->RGB conversion will has its issues, but even some defaults better than nothing Also, "Black and white" layer could use a similar switch for "Ligtness meaning" - and give "L" channel as another alternative to color tones mixing Thanks in advance!
