11 Colouring or glazing?
Let me explain a bit about the digital glazing technique. The whole work is done in greyscale with attention to values. Afterwards I use layers and different blending modes – Multiply, Overlay, Color, Soft Light and so on to add colour on top. In other words, I’m colouring the image. First, I flatten all the layers. Then, using the Correct colors tool (select Effects>Tonal Control> Correct colors) I choose the red channel and adjust the curve until I achieve some reddish/brown values.
