Set Color & Start Painting
More often than anything else, this technique will be used when you have a photograph of someone inside a house - there isn't a lot "wrong" with the photo I'm working with but we're going to play anyways.
The first step here is to set your foreground color. Think of natural lighting colors - a very light, almost-white yellow, oranges, etc. Make sure that any color you use is nearly white, but not quite.
Then, grab a brush - it doesn't really matter what one, as long as it's not too large. Create a new layer (Layer, New, New Layer) and start painting the areas that could use highlighting. |
