I've used the overlay mode also to flat the skin on portraits.... paint with a nice color (taken from skin) over the face on a transparent layer.... set the layer to overlay and adjust the opacity down or double the layer.... with some experimenting you'll get a flatter skin.... P.S. Paint only over the problem zones :-D retro The show is cool….

I’ve only one word to describe this episode: Awsome!

Keep on!

About overlay mode In GIMP this is identical to soft light mode due to a bug. Anyway, both modes result in a similar effect. One can describe overlay mode as a mix of multiply and screen mode. Multiply mode darkens the image whereas screen mode lightens the image (it is in fact the inverse of multiply mode). Overlay mode thus darkens dark areas and lightens bright areas, in other words it enhances contrast. By inverting a layer however and converting it into B&W, its bright areas become dark gray/black and its dark areas become light gray/white. In this way one achieves the opposite: the layer in overlay mode will brighten shadow areas and darken bright areas; contrast will be reduced. This explains why the lady in the shadow became visible without washing out the sunny areas in the picture. As you did in your show, overlay mode is also useful for increasing locally contrast by painting in black and white on a transparent layer in overlay mode: the dodge and burn layer. Black painting darkens whereas white painting lightens. As you surely know, dodging and burning are dark room techniques. It is not invented in the digital age. Hope it helps. That was an interesting show.
