8 outa 10
tough, yes but some ways I tell:
repeated patterns (the nail heads)
lack of true detail... a vague feeling of form but no substance..
like the drops on the oversaturated grass LOOK drawn on.
The glasses appear well drawn but the pic has an overall "flat" look.
Finally, the silverware... the spoon especially looks like an idea instead of an object.
BTW, I stopped worrying about "artifacts" when I first saw the "Add Noise" command in Picture Publisher....
I missed the table one. I thought all those glares were too pretty to be real. heh.
the trick is to look for [even the slightest] noise in the pictures. CG's wouldn't have noise :)
I got 10 out of 10 on the first try, and got 3 out of 4 on the bonus round. I missed the pills on the bonus round. My husband does CG and I do photography, so I kinda knew what to look for! :)
I've done this a couple times before actually, but I didn't remember more than one. Although, this test was one of the things that has helped me to be able to distingush between real and CGed things otherwise.
EDIT: Nevermind, I found the bonus, although I had to try typing things in the address bar to get it, how did you guys?
