The human eye is remarkably perceptive at picking out features in a photograph that are made up of essentially straight lines and that those lines are not parallel, either horizontally or vertically, with the overall print itself. These straight lines may well be the horizon, but they may also be an object in your photo that has straight lines such as buildings or walls etc .. This article describes a correction method using your typical image manipulation editor (Adobe Photoshop in our case)that can take less than five minutes to turn that mundane snapshot into a photograph that is very pleasing to the eye.
