Thanks all. I started with PhotoLab a couple weeks ago when I discovered and tried it in the last hour of the Black Friday 1/2 price sale (very thankful for that sale). I had seen it mentioned before in reviews of raw processors.
I’ve used it for a number of photos now and am very impressed with how quickly it makes good quality images. Really enjoying the Local Adjustment – especially when using a stylus. But I can tell PL is undergoing some changes and has rough spots. For instance, I’m disappointed that the HSL has so few colors to select for adjustment (and the Green seems practically useless for green in nature shots – have to use only yellow for leaves and grass). Thankful, though, I can use the Local Adjustment Control Point to select any color – but would be nice to be able to broaden or maybe reduce the size of the color range to be included together with the color selected.
Anyway, yes, I thought the icon that looks like layers was for layers – for a new mask on a new layer.
Even though I understood that you can place another mask overlapping the same region of a different mask, I think that because of the way the ‘new mask’ icon looked, and then adding to that this following line I’ve quoted from the DxO Help, the idea of having ‘layers’ got into my head and lingered.
“You can layer several graduated filters in the same area with a new adjustment each time.”
(I understood what that’s saying right off, but it also put the word "layers’ in my head. Maybe the word ‘overlap’ might avoid the potential for confusion?)
So thanks for helping me get rid of the notion that mask layers might be something to use.
