Excellent! Nine out of ten answers were correct 
I love these things…
10 for 10
than 3 for 4
hehe they are great hey.
Oh just redid it.. and got 10/10 4/4
Those last 4 were and odd choice. 2 really obvious CG ones and 2 that could go either way
10/10 here too…but i found the choice very odd and mostly very easy to tell…esp for example the apes…a well known pic in addition as it´s some ImageStudio Ad…and most of the cgi ones werent really good…at least there are better out there 
9/10…missed one
9/10 missed one
10/10 and 4/4
those seemed to be pretty easy… or was it just me? Or maybe we are simply better at this.
8/10 4/4 I always think one or two have to a trick like a photo they made look fake in photoshop
8/10
10/10 4/4..
not to be fooled here, heheh..
K.
10/10 4/4 Way too easy… 
Mare
YEAH!! 10/10 4/4 But I’ve got to say I kind of guessed at some of them. Just had a gut feeling about some that pushed me in one direction or the other. Still, some pretty nice renders for alias renderer, assuming there’s probably a few MR images in there.
totally lame…liked the first one better.
These images are very obvious…the CG’s don’t really look like real photos…The first one was better
10/10 and 4/4
then went to the first test, for the first time : 6/10
kinda proves your point pdaman!
10/10 then 2/4. Most of them were due to minor details most people wouldnt have bothered modeling or texturing.
Good Fun
Great Fun
9/10 - 3/4 I would like to see this same challenge with animations - or even images with motion blur - that would sort the mean from the boys
What gives away the cork puller pic? I thought it was CG, could have easily been CG imo.
look on the right of the handle, there is a smudge, usually artists dont goto that amount of detail on a whim
that’s how i got it as well 
the one that threw me was the bolt - i thought the DOF looked too exaggerated.
