Part I<\/a> – The revolution realized It’s common when correcting distortions in ultrawide lenses to end up with a ‘mustache’ effect in originally straight lines. You can see it in my corrected images taken with the otherwise excellent 20mm f\/3.5 UD Nikkor<\/a>.<\/p>\n The 1.54mm (13mm equivalent on FFE) ultrawide (UWA) lens in the iPhone 11 and iPhone 11 Pro suffers from this malady. Use the distortion correction slider in LR and you get the mustache.<\/p>\n Here’s the uncorrected original image – Apple applies no distortion correction to images taken with the UWA:<\/p>\n You can correct the distortion using this setting in the LR Develop module, and get the mustache distortion: Or you can manually invoke my newly created lens correction profile for the UWA thus, using the Develop module, for truly straight lines at the edges: Here is the comparison of the LR corrected image, left, with that corrected using my lens correction profile, on the right: Now you can use that wild UWA lens in the iPhone 11\/11 Pro for architectural images.<\/p>\n Go to my Lens Profiles page<\/a> to download the profile – jump to the end. That page includes installation instructions which must be followed carefully if the profile is to show up in the LR Develop module.<\/p>\n This profile works with JPGs only<\/b>, not with RAW files unlike the other profiles in that linked page.<\/p>\n","protected":false},"excerpt":{"rendered":" No more mustaches.
