CON­VERG­ING VER­TI­CALS / KEY­STONE EF­FECT

Digital SLR Photography - - The Beginner ’s Guide -

as it’s gen­er­ally in­evitable that a build­ing will tower above where you’re shoot­ing, the ver­ti­cal lines of a build­ing will be­gin to con­verge into the dis­tance as the build­ing moves fur­ther away from the cam­era. some­times this can have wanted ef­fects, for in­stance shoot­ing amongst sky­scrapers to em­pha­size their height, but most of the time you want the wide field- of- view with the ver­ti­cal lines of your build­ing par­al­lel. pro­fes­sional ar­chi­tec­tural pho­tog­ra­phers may in­vest in a tilt- shift lens/ per­spec­tive con­trol lens to avoid this Key­stone ef­fect, but for most of us this is out of our reach and we need to man­u­ally fix this con­ver­gence in pho­to­shop ( see p64 for how).
