This is an old article of mine. I leave it here for reference. Maybe someone finds it useful.
Some time ago I spent a few hours taking photos of a checkerboard and loading it into Adobe Lens Profile Creator. All of this were steps to create a lens correction profile for my wide-angle Samyang lens and Nikon camera (APS-C DSLR). The lens is Samyang AE 14mm 1:2.8 ED AS IF UMC to be precise.
Profile creator from Adobe is actually quite handy tool that allows average amateur to create lens profiles for Lightroom and Camera Raw without the need of having specialized equipment. You just need a printer (to print the checkerboard), tripod and camera with lens attached. And a few hours. Just read instructions coming with profile creator download if you want to create a profile for your lens. But check Adobe’s database of user contributed profiles first (I could not find my Samyang lens and this is why I created the profile myself).
My profile should work properly with any Nikon APS-C DSLR camera and with non “AE” version of the lens. You can find a download link at the bottom of the page. If I ever become a happy owner of a full frame one, I will update the profile and publish it here.
Installation To install the profile quit Lightroom 3 and unzip the archive to lens profiles folder of Camera Raw installation. This folder for Lightroom 3 is:
- On Windows XP: C:\Documents and Settings\All Users\Application Data\Adobe\CameraRaw\LensProfiles\1.0\
- On Windows Vista/7: C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\
- On Mac OS X: /Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/
For Lightroom 4 the folders are:
- On Windows XP: XP is no longer supported (see current system requirements).
- On Windows Vista/7/8: C:\Users[your user]\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\
- On Mac OS X: /Users/[your user]/Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/
And that’s it! Launch Lightroom, select a photo taken with Nikon APS-C DSLR and Samyang 14mm lens, and apply the lens profile. With “AE” lens Lightroom will probably automatically match the profile (at least with NEF images). If it does not, just select the profile manually from the list.
