Dodge and Burn on Masks

[Jim Hardiman]

When I refine masks in PS, I routinely nudge the mask by blurring the edge (this can be done in AF using the Blur Tool on the Mask) and then using Dodge and Burn Tools to move the mask one way or the other.  In AF, the dodge and burn tools do not affect a mask for some reason.  This would be a great feature.

I agree this should be possible.

 

At first, I though that using the regular brush tool in Overlay or Soft Light mode with black or white selected might be a feasible workaround, but it turns out that for some reason the brush blend mode is ignored when painting onto masks. Moreover, even though Affinity supports multiple masks, these masks always seem to blend essentially in Multiply mode, making it impossible to replicate the effect using multiple mask layers (same goes for other things such as performing boolean operations with masks using blend modes).

Peter,

 

My solution was to turn the mask back into a grayscale layer, do the edits, that then rasterize the layer to a mask and then replace the mask.  I may have to do this a couple of times.  Clunky but it works.
