1. Re: Changing a lens profile in Notepad?
ssprengel Apr 28, 2014 2:15 PM (in response to retiredff)A profile from a crop-frame camera won’t be recognized for a full-frame camera but otherwise things should work, and changing the camera in Notepad shouldn’t be necessary.
What is necessary is you put downloaded camera profiles in a folder other than where LR puts the Adobe profiles, because LR only looks for known profiles in the LR Resources folder.
If this is Windows, then any third-party/user-created lens profiles should go into a place under your Users folder:
%APPDATA%\Adobe\CameraRaw\LensProfiles\1.0\
Where %APPDATA% is a system variable that maps to c:\Users\yourusername\AppData\Roaming but AppData is a hidden folder so it’s not obvious where to go in Explorer so typing %APPDATA% into Explorer’s address bar and hitting Enter is the easiest unless you’ve turned on visibility for hidden and system folders.

I recieved a Samyang 14mm F2/8 (used on Canon 50D) this weekend, and can not find a profile for it. I did find one for the Canon 40D using the Adobe Lens Profile Downloader, and it is not recognized in LR 5.3, on Windows 7.
The Adobe Lens Profile Downloader should automatically install the profile to the correct user folder. Check as ssprengel has outlined to be sure the profile is actaully in the correct folder. The only profile I see is for raw image files. If you are using JPEG image files this raw profile will not show inside LR in the Lens Profile list. You can edit the lens profile in Notepad so that it will work with JPEGs and save it with a different name (add_JPEG). Keep in mind the vignetting correction is slightly different for raw files than JPEGs, but the distortion correction should be the same. You may need to set the Vignetting slider to a higher or lower setting than 100 to get a closer match for JPEGs. Procedure here:

retiredff Apr 29, 2014 7:13 AM (in response to trshaner)I would be using it for raw files. In all honesty, just trying for a shortcut while I play with the lens! Any minor issues I find I can correct. Thank you!

ssprengel Apr 29, 2014 7:18 AM (in response to retiredff)So the lens profile is in the right location and the reason you weren't seen it is you were viewing a JPG not a raw file, but in the normal situation you will be viewing raw files so everything is ok?
Or do you mean that the ALPD put the profile in the LR-reserved folder instead of the users-custom folder and you'll need to move it before it'll be seen for raw files?
