Cool! Hadn't thought about that -- makes the images even more intriguing!Ashwin,
What I found interesting (at least for myself, I did), is that in the last 5-6 images you posted of individuals looking at photographs, I just assumed they were looking at B&W printed photo's. Indeed they may have been B&W and of course this is emphasized by this being a monochrom thread.... but on the other hand they (the printed photographs they are holding) just as well could have been in color. It's sort of the "mind" paying tricks on perception.
