I’m forever astonished to see how Photoshop users take the software and just do the most creative things – from creating vast scenes of composites to making a world that doesn’t exist. For my type of photography, I typically am more concerned with the retouching of people, and altering light states, and perhaps some mood alteration.
On the odd occasion, however, I will cut a person out of a scene, usually from a seamless backdrop, and onto/into another scene. This could just be to alter the color of the background onto a collage or something. Dealing with a subject’s hair in the cut-out process, can be excruciatingly tedious though clearly from the video you’re about to watch, it needn’t be.
Aaron Nace, with his trademark geeky humor and effortless teaching ability, gives the key to unlocking the secret to cutting out hair seamlessly. There is one small caveat – it is much easier to do this using dark hair against a light backdrop. Essentially using contrast to allow for easier separation.
What you’ll be doing is using ‘Channels’ to find which solar channel shows the most contrast between hair and backdrop. Once you’ve decided on this, you can up the contrast in the channel even more, and your selection in channels will carry over onto the layer you’re working in. Back in layers, all that was dark will turn invisible and a simple inversion of this will cut out the background.
From this point all you’ll need to do is concern yourself really with the fringing, the light colored halo that surrounds the cutout of your subject, which is apparent in pretty much any selection you make in Photoshop. Aaron’s method to deal with this is the easiest way I’ve seen, and very effective, and much better than dematting or ‘refine edge’. Actually, the whole process, is generally much better than the other methods you may have used, or avoided, before.
As always, if you are a fan of Aaron’s teachings (and who isn’t?), be sure to check back here for updates, and follow along with Aaron on YouTube and Phlearn. You should also consider becoming quickly adept at Photoshop with the Phlearn Photoshop 101 & 201 sets as they are extremely comprehensive, and will have you quickly doing things with Photoshop you may have otherwise thought too complex, or didn’t even know you could do.
