Well, I have my doubts about third person "close", as well. I haven't yet been convinced there is such a thing. There sure wasn't back when I first started writing, nor when I went through the university. Or if there was, I never found it in a book, and it never came up in any writing class. I've tried tracing in back, and it seems to be an internet phenomenon, and most of the examples I've found come from writers who don't know the difference between thrid person limited and third person omniscient. And from some who simply get a blank look when they hear "Third person limited."
Third person limited just means you're limited to a single POV character at a time, not that you're closer or farther away than you want to be.
In fact, third person "close" should mean you're closer, and can write
more things about the POV character, not fewer. I also can't find a single published novel written in third person that doesn't follow the classic definition of third person limited, which is that you can reveal anything the POV character tastes, sees, hears, smells, touches, feels, thinks, or knows. First person aside, it's impossible to get any closer than third person limited. (Unless you fall on the odd side of the argument with second person.)
I have found recent how-to books that list third person "close", but once again, the novels these writers write violate the rule of "can't write what she isn't thinking" about every other page.
Most of these writers also fail to even mention third person limited, even though about 90% of all published novels use third person limited. One selling writer even had an article in Writer's Digest listing the top five POVs, and third person limited wasn't even on her list, even though no other POV comes close.
There are many lousy definitions on the internet, and, actually, "camera POV" isn't third person limited, it's "dramatic POV", if you come from the stage, and "Objective POV" if you come from fiction. To me, it's "dramatic."
Camera POV, really another made-up term to help explain "Objective" or "dramatic," is just like watching a stage play, or a movie that doesn't use voice over to get around the POV when needed.
It means you can only write what the camera can see, which means no writing at all about what the POV character is thinking, feeling emotionally, etc. You aren't allowed to get inside any character's head in any way, not even that of the POV character. Even if the character is thinking "I'm hungry." she has to say so, or you can't mention it. No getting inside a head at all, in any way.
The most famous example of this POV is Hemingway's short story
Hills Like White Elephants. http://www.gummyprint.com/blog/archives/hills-like-white-elephants-complete-story/
Having said all this, I very seldom describe a POV character in any way, not because it violates POV, but because readers like to identify with the main character, and the moment you give the character green eyes, or curly black hair, I think it's tougher for the reader to become that character.
