For a small project I'm participating in, I would like to poll people on which one of these images looks more realistic. (Click on the image for a larger version.) They have been rendered using slightly different methods. Since I don't think I have the permissions to create polls on this forum (or if I do, I don't know how), you can vote here instead: http://www.strawpoll.me/11451622

Hey, here's something you didn't ask for: The top image is the average of the two images. The bottom is the difference. I think the average looks best, but whatever.

Honest Answer: Bottom. Issue with both is that the black ball has not been corrected for it. Bottom is more realistic however still needs corrections.

I don’t see much difference, so I voted “Both look equally realistic”.

Voted for the top one. Quite clearly it looks more realistic because it has more reflections and also slightly better shadows. Although reality may not have that much reflections, depending on what material the floor and red ball is made of.

Thanks for your answers. The top image makes color calculations (eg. in surface lighting) in terms of perceived colors (in practice in terms of raw pixel values). In other words, for example, if a surface at some point reflects half of the incoming light, a 100% white light will get reflected as 50% gray (ie. if in terms of pixels, a white pixel being (255, 255, 255), the surface will have a color of half of that, ie. (127, 127, 127).) The bottom image makes such calculations in terms of absolute light energy, rather than perceived brightness. In practice this means that eg. said surface would look approximately as 73% gray (ie. its pixels would be about (186, 186, 186).) It also affects all the other kinds of color calculations (such as color mixing in reflections). In theory the latter should be more physically accurate, so I wanted to see which version unbiased people would think is more realistic.

The top looks imo more realistic assuming they were glass/metal orbs. The bottom looks more realistic if it were plastic-ish.

The shading on the wall in the upper image looks exagerated. I also wonder why there are reflections on the red/white ball in the upper image while they aren't visible in the lower one. How does monitor gamma influence the results?

I chose the bottom image, because the shine on the red-and-white ball looked more realistic in that one than it did the other one.
