Unlike Plug-ins, Extensions or other External Image Editing Softwares, Photoshop Actions are already a built-in feature of Photoshop!
If you are not using Photoshop Actions to help speed up and streamline your editing, you're missing out on a huge trick.
Photoshop comes with the capability to 'record' a series of steps taken when editing an image and to save this as an 'action'. You can then 'play the action' every time you wish to recreate these steps on a new image. Neat!
LSP Photoshop Actions take this not just one step further, but in leaps and bounds to make sure you never have a bad editing day again. Some of the LSP Actions play upwards of 300 separate clicks to set up layers for you in just seconds... imagine how long this would take you in real time!?!
Once you install your LSP Action set into Photoshop, it will always be there for you whenever you wish to use it. You can use LSP Actions for a complete edit, a part edit or only sometimes - it's up to you!

You can see and play your LSP Actions by opening up the actions palette (see below for more help). Then you simply click on an action (ie Reduce The Reds) and it will play out as a separate layer with a layer mask. You then paint this on to your image as you wish! You can leave it as it is, or you can play with the opacity of the effect, play again for a stronger effect, edit it yourself if you wish... the freedom with LSP Actions is phenomenal for beginners and experts alike.
