Once purchased use the link to download the Drifting Photoshop Action. Install by opening photoshop and your actions panel then clicking on the icon top right and “Load Actions” navigate to your downloaded action and Open. In your actions panel you should now see a new action set called Drifting Colour Toning Action. To run this action click “Play Selection” at the bottom of the actions palette. Adjust the opacity of the various layers to suit your image. I have also provided a “Darken” and “Lighten” layer which can be used if the result requires some further tweaking to overall luminosity values, adjust the layer opacity of these to suit your image.
