How to use this action:
There is a file included that says how the action should be used, but it isn't completely correct, so here is the full how-to.
- Open an image in Photoshop - Run Part 1 of the action - Select a sharpness that you think looks good - Click on the layer mask on the layer between the Levels layer and the Brightness/Contrast layer (if you have opened an image straight into Photoshop this should be called Layer 1) - Select a black round brush big enough to cover all of the image but the corners at around 20% opacity - Click on the centre of the image. Repeat until you are happy with the saturation - Click on the very top layer - Press cmd+alt+shift+e (Mac) or ctrl+alt+shift+e (PC) - Rename the layer 'Layer 7' - Run part two of the action - Done
