Hi everybody and thanks in advance to those who will follow the thread.
I need to change the tiles on a floor and a wall, but then I must keep the original shadows.
After changed the floor tiles, I've tried to restore the shadows making a copy of the background, than desaturated and inverted the copy and adjusted the levels for obtain a good b/w image, than inverted again and put this copy over the new tiles with multiply effect.
Unfortunately the result is quite ugly.
I attach the original image (first one) and the modified one without shadows (it's only an example), hoping someone can help me.
