If you are photographing people, one of the most fundamental skills you will need is the ability to retouch blemishes. If you are new to the process, this helpful video will show you how to use Photoshop to do it.
Coming to you from Aaron Nace with Phlearn, this helpful video will show you how to remove blemishes in Photoshop. This is one of the most important skills you will need if you plan on working with people, and while you can learn the techniques pretty quickly, it is equally crucial to develop a good sense for how much retouching is the right amount. Because blemishes are a local aspect of an image, you will often be fairly zoomed in when working on them, and that can make it easy to lose track of the overall effect your post-processing work is having, and you might end up going a bit overboard. I like to zoom out every 30 seconds or so just to keep an eye on things. Overall, retouching is something you definitely want to do in moderation to keep your subjects looking as realistic as possible. Check out the video above for the full rundown from Nace.
