A tool used to ‘paint’ adjustments on to an image manually, and one of the key adjustment tools in Lightroom, for example. You may need to choose the adjustments you want to make, e.g. exposure, saturation, clarity and so on before you start painting although non-destructive photo editors let you make changes to these settings afterwards too. You can change the size, softness and opacity of the Adjustment Brush.
