Handy Techniques for Cutting Out Hair in Photoshop
This post was originally published in 2009 The tips and techniques explained may be outdated. When trimming out images in Photoshop, human hair or animal fur always proves troublesome and can be tricky to achieve a realistic look. Here are two techniques I use on images with both plain backgrounds, and those with a varied background tones, each achieving pretty decent end results. Technique One: Images with Plain Backgrounds The best photos are those professional studio type shots that are taken against a plain white background. These shots make it much easier to find the edges of the subject, but trimming out fine hairs can still be a little tricky. Open up your image in Photoshop. Head over to the Channels palette and review each of the Red, Green and Blue channels. With only the new channel selected, adjust the Levels (CMD+L) to dramatically increase the contrast between light and dark areas. Due to the slight variation in tone of the background, it appears grey in the darker areas.
