Photoshop actions are a great way to speed up your workflow. If you're not sure how to create them yourself or maybe you're just a bit of a lazybones, then take a gander at this amazing giveaway.
Coming to you from Unmesh Dinda of PiXimperfect, one of Youtube's most prolific Photoshop educators, is a series of 10 Photoshop actions he has made available to download for free here. In the video, Dinda explains how to use each one while also providing a handy timestamp list so the viewer can bookmark the page and skip to the desired explanation when needed.
If you're not familiar with Photoshop Actions, let me briefly explain: if you're a regular user of the program, then you will end up carrying out the same steps over and over again depending on the type of work you do on your images. This can be very time-consuming if you're processing a large number of images and also quite tedious. An action is like an automated series of steps that can be programed once and then carried out after with the simple click of a button. Making your own actions is super easy, and Fstoppers' own Robert Baggs wrote an easy-to-follow tutorial on it a while back; you can read it here.
