Hello, I would need your help with the superposition of 2 images. I opened an image and copied (rectangular selection) the face of a second image. With the eraser, I had erased the parts that did not interest me and the first image remained intact. The problem is that I can't remember how I did it. (My example: face copied on the first image face and jacket of a man and by erasing the unnecessary part of the second image, the jacket reappeared as I wished). A big thank-you
