Pushing the palette
7To darken the outer areas like a vignette, I create a new layer and set it to Soft light mode. Then I choose a dark blue and drag it from the Color palette onto the canvas. This activates a new flood-fill tool that darkens the image. I erase the centre with a soft airbrush and adjust layer Opacity. Creating an Add layer and using a saturated soft brush creates a nice glow in lit areas.
