When we take a photograph, and we tilt the lens up or down, the image we will obtain will have distorted vertical lines, a product of forcing perspective. The lines that our eyes see vertical will tend to converge at one point. Currently, even with a simple APP on mobile devices, we have tools to correct this distortion. I leave you an example of the Arc de Triomphe in Barcelona, with the corrected vertical lines. Arc de Triomphe Camera: iPhone Edition: Snapseed Location: Barcelona - Spain Photo author: avrorp
