Hi, folks! In this handy tutorial, we're going to be talking about gradient maps. What are they? How do they work? How can you use them in photomanipulations? See below!
What are gradient maps and how do they work?
A gradient map is a type of an adjustment layer in Photoshop, which (unlike a traditional gradient fill, which fills an area using a linear or radiant blend of colors) uses the lightness/darkness values in the image as a map for how the colours are applied. This means that you can manipulate each value separately, assigning a different colour to your midtones, shadows, highlights and everything in between. It allows you to change the colour of an object in a much more believable and realistic way than, for example, using the Colour or Hue blending modes.
To use a Gradient Map, you need to go into Layer -> New Adjustment Layer -> Gradient Map menu in
