Photos Make for Subjective Analysis
"I don't see anything special there, even though I do see a yellow gradient on another user's photo."
@Northgrove: I checked the link, and when the linked photo is displayed, I can make the so-called yellow go away by just tilting my screen a little, so that my overhead fluorescents aren't shining directly on it.
Using photos to determine something like yellowing becomes a matter of subjectivity. One has to take into account the color balance and accuracy of the capturing system (the camera), the color balance and accuracy of the display that is displaying the photo, and the interpreter's eye. If one uses a software analysis system, the accuracy of the photo still plays into the inaccuracies.
