Green can be a particularly unflattering color to have present in the skin, as it can make people look rather sickly. If you shoot portraits outdoors, it will often appear in the subject's skin. Luckily, it is not particularly hard to correct, and this excellent video tutorial will show you how to fix it quickly and effectively using Photoshop.
Coming to you from Unmesh Dinda of PiXimperfect, this great video tutorial will show you how to quickly and easily remove green color casts from skin using Photoshop. If you are shooting in the studio, this will rarely be a problem, but if you are photographing portraits outdoors, you will often catch a bit of a green cast due to light being reflected off the grass and foliage. As such, it is something you will want to watch for carefully when you pull up the files on your computer. Once you need to fix it, though, it is not particularly hard. As Dinda shows, it is helpful to pull the hue slider all the way to the left or right while you are refining the target colors, as this will make it plainly obvious exactly where you are affecting with your edit. Check out the video above for the full rundown from Dinda.
