How to map a fractal image to a photo using Photoshop. This is only the absolute basics. I don’t cover for example, how to recover the image where you don’t want the fractal. To do this, make sure your foreground colour is black, then use the brush with a low opacity level to paint on the mask. This will softly reveal what is underneath.
