ajw874 Posted February 28, 2018 Share Posted February 28, 2018 I have a colour photo, to which i add Black & White Adjustment layer, I want to adjust the RGB sliders so they only work on a selected area, not the whole B&W picture. I can't seem to figure how - I've tried using masks. Any advice, or are there any tutorials dealing with this? Thanks Quote Link to comment Share on other sites More sharing options...
h_d Posted February 28, 2018 Share Posted February 28, 2018 (edited) Hi ajw874 How about this: Original coloured image: Add two black and white adjustment layers, and nest them both inside the Background image layer (make sure you see the blue vertical bar as you drag): For now, close the sliders panels. Invert the upper black and white adjustment layer (Click once on it to select, then go to the Layer menu and choose Invert). You'll see a black area across the thumbnail: Select the area you want to modify using your favourite selection tools: (My selection is very rough and ready, yours will be much better). Fill this selection with white (you'll see the thumbnail change, the image won't at this stage): Deselect if you wish. Double-click on the thumbnail in the upper Black and White adjustment to display the sliders. Drag them to your heart's content: Hope this helps. (Adjustment layers are their own masks, you don't need to create additional mask layers.)

Thanks If you want to apply an adjustment to just one area, make a pixel selection first. Such as the penguin on the left. When you apply an adjustment layer (like B & W), it is applied to the selection area only. You could then invert the selection Select > Invert Pixel Selection and apply a different adjustment to that. In this case a Recolour Adjustment, but it could be anything The B & W adjustment is applied to the penguin on the left, the recolour adjustment to everything else (inverted selection). . The point being, the adjustment is only applied to the area that is selected when you add an adjustment layer. Quote Windows PCs. Photo and Designer, latest non-beta versions.

ajw874 Posted March 1, 2018 Author Share Posted March 1, 2018 Thanks h_d that's great, just what I want. Oddly though, it only works for me if I place the selected/white-filled layer underneath the other layer; instead of on top as you do. Guess I need to get my head around nesting layers.

h_d Posted March 1, 2018 Share Posted March 1, 2018 One of James Ritson's excellent tutorial videos explains the difference between clipping and masking. The drag method used to achieve masking (when you get the vertical blue line before you drop the layer) is slightly fiddly, but works well once you get a feel for it.

When I first started using Affinity I thought that you had to drop the masking layer onto the narrow space to the right of the thumbnail of the masked layer (where the vertical blue line appears) but that is not true. Once I figured out that the masking layer can be dropped onto the thumbnail of the masked layer itself, I realized that it was not as fiddly as I first thought. h_d 1 Quote All 3 1.10.8, & all 3 V2.4.1 Mac apps; 2020 iMac 27"; 3.8GHz i7, Radeon Pro 5700, 32GB RAM; macOS 10.15.7 Affinity Photo 1.10.8; Affinity Designer 1.108; & all 3 V2 apps for iPad; 6th Generation iPad 32 GB; Apple Pencil; iPadOS 15.7 Link to comment Share on other sites More sharing options...

What have you tried? Some screenshots (including the Layers panel) and a description of your process would help.

HVDB Photography Posted December 1, 2018 Share Posted December 1, 2018 Perhaps a selective colour range using a HSL desaturation adjustment could also be an option ?
