Lenses in­tro­duc­ing er­rors? Dis­cover Light­room’s ar­ray of lens cor­rec­tion tools

With Light­room’s range of pow­er­ful tools, fix­ing lens and per­spec­tive is­sues is a quick and easy af­fair. This month, we’ll look at a few com­mon prob­lems.

First off, there’s dis­tor­tion in our fac­tory scene, with the wide-an­gle lens mak­ing straight lines look bowed. Light­room has a data­base of lenses with in­for­ma­tion on dis­tor­tion is­sues for par­tic­u­lar lenses at spe­cific fo­cal lengths, so as long as the lens is in­cluded in the im­age EXIF data (it will be if you shoot in RAW) then fix­ing dis­tor­tion is a sin­gle-click job.

Chro­matic aber­ra­tion can be a prob­lem, es­pe­cially with cheaper lenses and wider aper­tures. Again, this is usu­ally a one-click fix, al­though if you want pre­cise con­trol then Light­room 5 lets you choose which colours to re­move. Fi­nally, there are the Up­right but­tons. With these im­pres­sive tools, fix­ing keyston­ing, cam­era tilt and per­spec­tive prob­lems has never been so sim­ple.
