Should a screen capture be legally binding in any way? We like to think that taking a screencap of a great price or another problem is a foolproof way to hold on to evidence, but there’s a small flaw in that plan. It’s called “image manipulation.” Or, to use a trademarked term, Photoshop. This is probably the reason why Amazon refuses to take the screencap that Anthony took of a sunglasses description as rock-solid proof that they had an error in their listings. He says that he grabbed the image for a different reason, but was glad to have it when Amazon claimed that the sunglasses he bought as polarized were actually non-polarized.
