Next, create the background layer called 'Colour'. Select a colour of R:127 G:53 B:41 and fill a new layer underneath the model shot with it. Create a layer between the other two called 'Gradient' and fill it with a Radial Gradient (G) with its centre in the centre of the composition horizontally and in line with the centre of the model's head vertically. Then set its blending mode to Multiply to get the effect shown.
