This is another excellent tutorial from BlendedPlanet. I'm sure you all remember the previous tutorials and resources we've posted from BlendedPlanet. This new one covers one of the most difficult things to key, hair.
The thing that I most liked about this tutorial is how enjoyable it is to read. Take these lines for instance:
Good news, friends - I do believe I have stumbled upon the ultimate greenscreen technique, and if you're willing to go with me on a slightly wild ride into the mathematical basis for a perfect matte, I think you will agree. And, believe it or not, we will NOT be starting out with a green minus red color difference matte!
Well, ok, that's not completely true, but humor me for a bit, and let's assume that you HAVE pulled a reasonably good color difference key, but you went ahead and blurred the matte and eroded the edges a couple pixels. So what you have is a great key of your subject, but basically, the edges suck.
From that auspiscious starting we point we ask ourselves - how to restore EXQUISITE edge detail, losing nothing in the process. Well, let's start with a little theory, some assumptions that can guide us on the way. This may not all make sense right now but try to stay with me.
Its very obvious the author is passionate about what he is sharing and it really reaches out to the reader and I know that it made me want to keep reading. The technique really results in some great keying, their appears to be little to no loss in quality and the soft edges of the hair.
Its recommended to download the .blend file as the article doesn't carry itself with a large amount of screenshots, rather the minimum to keep things understandable. Well I'm sure you'd like to check out the tutorial, it can be found here.
