How to set up a Photoshop Action to edit multiple photos

How to set up a Photoshop action - step 3

When you shoot dozens of similar shots in the same location, you may end up needing to tweak loads of nearly identical photos. 
You could slog through each photo one at a time, tweaking contrast using a Curves Adjustment Layer and then adding a Hue/Saturation Adjustment Layer to boost colour, but this repetitive editing process could take ages. A faster way to tackle a group of photos with similar photo-fixing needs is to condense multiple editing commands into a single Photoshop Action.
