In this tutorial, Glyn Dewis will show you how you can add mood and atmosphere to your pictures, using colour and a little know feature, Photoshop Lookup tables.
Basically Color Lookup Tables are just that, a table of predefined colors that can be applied to an image, replacing in a controlled way the colors of the destination image. It is widely used in video, but also in still imaging.
At the end, Glyn shows you a very quick and simple way that you can then save unique looks and apply them with just one click.
