Interesting video - the Sally/Anne effect was something I wasn't aware of. To further complicate the issue of color perception when dealing with photos viewed on a computer monitor, you never know what kind of monitor your photo will be viewed on or how that monitor might have been adjusted or calibrated, all of which can drastically affect how an image looks. And images look very different on Macs & PCs as well. So when we post our photographic "masterpieces" & they appear to be underappreciated, we can just assume it's either a color perception or monitor calibration problem & feel better about ourselves, right?
