Dude, I know what we're talking about.
The iTouch shouldn't have been included then, should it?
And it IS about the angles. If you knew anything about LCD's, you would know that except for the most expensive panels, they ALL exhibit color variation from panel to panel in the same production batch.
You SHOULD also know that when moved at an angle any small color variation will be exaggerated. Even on a desktop monitor you will see that by looking to the ends of the monitor while keeping your head in the middle.
So, yes, the angles of the shots do matter. He knew that by shooting a more extreme angle. What we also need is a shot where the center of the lens is at the center height of the screens vertically for one. Secondly, as the camera is also off angle to the side phones, it also exaggerates any difference.
As you KNOW, all LCD screens look darker when you move your head down from the center line, and lighter when you move it up. The color also changes in opposite directions. Therefore, the fact that the camera angle horizontally across the picture is well past the side on the right of the phone on the left, and well past the left of the phone on the right will also bias the picture towards exaggeration.
I hope that helps you. I really didn't think it was required to give that basic lesson on LCD technology, as I thought everyone here already understood it, and that the way the pics were taken was either an oversight, or was just quickly done. Otherwise, an individual picture of each device would be required, shot from the very center of the screens, and then comp'd together. Too much work for a Saturday night.
