Retouching tools in Photoshop CC
Raw or heal
Photoshop CC’s Camera Raw filter now has the best retouching tool, but the Spot Healing Brush is fine for small spots and blemishes.
Brus h over
The Clone Stamp tool is ideal for painting another part of an image (or another image) directly over something you want to remove.
The Spot Healing Brush and Clone Stamp work like other brushes — you can vary their size, opacity, softness, and other parameters.
Layers & Selections
Best practice is to retouch on a separate layer, using selections to define the areas of the image you want to affect and avoid overspill.
