This is the most pointless and un-usefull test I have ever seen.  Why don't you send us all 100 A4 prints and then we can judge properly.

70%
But that is mostly because I was influenced by judging them on format, subject, and level of photography.
To put that survey together must have cost the better part of a day. Good initiative allthough
survey is majorly flawed in that it does not prove anything.
As was said before; we need large files of both slr and mfb in similar circumstances.
I can do a test with Nikon D2X and Hasselblad H3D, but I think it is a no-brainer that the mb would be better. Anyway this whole story started about Canon throwing the gauntlet.
So who are the mfdb and canon owners who can do it?

I got 41%.  I must be blind.  I guess the next questions is, How to get rid of my newly upgraded H3D-31 and go for a DSLR.

51%, like "pps" (Paul). And like pps my choices were made on the same creterion: which format for that kind of job, since this seems to me the best criterion to be used here.

Impossible to make any other kind of selection, based on quality, "depth" (understand 3D), colours, sharpnes, DoF, etc ... of such images.

So does my and "pps"'s 51% suggest that 49% percent had chosen the wrong medium to shoot?

But that's another question.

This is laughable.  I am mad at myself for even posting on this thread.

Most people, even photographers, and myself, couldn't tell the difference of an 8X10 of a high end dslr or a MFDB exposed and processed properly, much less a web based jpeg!  good gosh.

That's why I took in my opinion the only valid criterion to choose: based on what should be the logical format (for me) to take this shot.

All the rest is senseless, IMO.

As pointed out by someone else, I could put pics of my newly bought 10 MPx Lumix and nobody would see a difference!

Oh no, how can you be using a tiny Lumix.  Surely you know that 39MP is the minimum these days.  You also need 16-bit otherwise the DR is so bad you cannot make out the freckles on your European skin under harsh Thai sunlight.  I'm sure someone will have a few web-sized images to post just to confirm my point.  Shame on you Thierry!

OK, I have a slightly less absurd, but still mostly stupid test.  You can have a look at a few shoots I have up on my website (I so need to update with new stuff).

 I've used 4 cameras in the Celeb section (loads automatically)   Aptus 22 H1, P45 H1, Canon 5d, Canon 1ds II.  For the most part my shots are F11+  and the crops are either double page or vertical making guessing based on crop a bit tougher.

 Yes these are retouched some far more than others.  Each shoot only uses 1 camera.  So you at least have 1 photographers eye the same throughout the photos.  Anybody think they can guess all 6 shoots right?

no you cannot, because the tiny sensor makes too much noise on brown skin. also we learned now that the 3d endering will be too less for too lo contrast from brown skin to green or brown backgrounds.
so it might happen that you will not see the model, at least not if it is nude ( what i will not hope anyway ).

again you have made your tests and learned your lesson: I am still in the trying phase.

As an emperor who wears only the very finest clothes that money can buy, I scored 100%, of course.

I'm surprised more so-called pros can't see the obvious (to emperors) 3D effect (is that the H3D effect or just an ordinary 3D effect ? Naturally, I can see both).

And those stunningly smooth transistions that even tiny, highly compressed jpgs can't hide. Not to mention color so real it bites yer bum off.

Really, there ought to be a forum just for emperors. Several here would qualify.

I got 54% bascially just judged from the feel of DOF.  For web publishing it is rather difficult, if not impossible to judge. I suppose MFDB is not design primary for the web publishing (at common size) but rather than fine art and high quality print/output.

It's way too early to draw any conclusions, certainly not "clear" evidence. I'm guessing that 60% success rate is within 1 standard deviation from 50% (ie. guessing). That would mean there is no statistically significant result of respondents accurately telling whether a shot is MDFB or dSLR. But I'll hold with statistical number crunching until I get a significant number of results - and we're not nearly there yet.

If the average goes above 60% then you are getting into 80-90% confidence that you can reject the null hypothesis (that is, that the choices are random) (SE is anot 10 out of 100, so, 45 to 55 is the expected score if the selections are basically 'random'))

Hehe, 57%. Well I guess That's $20k down the toilet then  

I also couldn't find the "or film" option avalable on the nudes. They were so appalingly clichéd that I can only assume them to have been taken in a pre digital age.
