Originally posted by Glen I've downloaded the Adobe lens profile downloader but what do I do with it now?
Quoting from the Adobe support page:
Adobe Lens Profile Downloader 1.0.1 Adobe Lens Profile Downloader is a free companion application to Photoshop CS6, Photoshop Lightroom 4, and the Camera Raw 7 plug-in. It allows customers to search, download, rate and comment on the online lens correction profiles that are created and shared by the user community.
In short it only helps you find profiles created by other users. It does not install the profiles.
Camera and lens profiles are found in the following locations:
Windows -
C:\Program Files\Adobe\Adobe Lightroom\Resources\CameraProfiles\Camera
C:\Program Files\Adobe\Adobe Lightroom\Resources\LensProfiles\1.0
Once you get to the 1.0 directory, it has subdirectories under it for each lens brand and under each brand a file for each lens.
