Re: what's 3-D?

The connection is that unsolicited comments made by non-Sigma users at multiple major photography and equipment shows on numerous separate occasions revealed an unusual number of comments about a "3D" appearance. These comments were not heard at other manufacturer's displays nor have they been reported as being commonplace as they were at the Sigma booths.

Of course, it would be good to hear this from an unbiased source and in a more controlled environment where variants on booth positions, crowd traffic can change or modify results one way or another.

What does this mean? I have no idea. But trying to quantify it is unjustified from a scientific perspective. Something appears to have a dimensional appearance or it looks flat. We could discuss possible reasons until the cows come home and still have no agreement because subjectivity is not quantifiable. It's not about "prefering" a Sigma over some other camera at all. It's about perceiving a 3D appearance from a Sigma photo.

Best regards,

I don't see the connection between this complex situation and trying to identify whether someone prefers Foveon to Bayer. Evidence could be gathered for that latter situation by providing a large set of identical images produced from different cameras and asking people to pick their favourite. If people always chose the Foveon, you would have strong evidence. If the results were random, you would have counter evidence.
