Burning & Dodging With Adjustment Layers And Masks
Non-destructive burning & dodging is most often done with a 50% gray fill layer. Although using this method has worked for me in the past, I’ve found it difficult to predict what sort of result I would ultimately attain when finished. Lately, I’ve been using adjustment layers with a mask to do my burning & dodging and I’ve found that I have more control over image tone and contrast.
The benefit of using this method is that once the layer mask is applied, you can easily re-open the layer adjustment dialogue box and change the amount of brightness or darkness given to particular areas.
