I want to colour just parts of an old black and white photo and add very subtle pink cheeks to the subject.......how can I do this in photo paint.....there must be a tutorial somewhere but everything I google search comes up with photoshop tutorials
Convert it to RGB, choose a light pink color and paint with the brush set to Color merge mode and adjust the transparency to your liking. For more control, create a new object above the original photo and paint on that so you can come back and change the color, transparency, etc. without affecting the original.
