Split-toning in GIMP


This tutorial is based on Rore’s Split-toning tutorial from gimp’s flicker group and also on one of meetthegimp.org podcasts . its a neat effect where you can have a cretin colour for highlights and another for shadows.

Getting started

The image i’m going to use for this example is off sxc.hu but you can use your own if you wish.

Step 9

In this final step we will lower the opacity of the Orange layer to 75 so we get more of the blue shade, this step is optional and it would differ from photo to photo.
