In LR4 some lens profiles are not available that are in LR3. It may well have to do with the fact that I "downgraded" some profiles that were only available as RAW versions to non-RAW versions. Unforgivable but I just don't always shoot in RAW. They do show up in LR 3 as I mentioned and I believe that they are stored in C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\ but get the idea that LR4 uses some otther directory... Is thatt right?
Sorry, no idea why the change was made....I just know that it was.
In the early days of the LR4beta there were quite a few comments about the respective size (within Program Files) of LR3 and LR4....the latter having a footprint of almost 800mb, LR3 being less than 100mb. To some, this was evidence of sloppy coding and application bloat, but of course they hadn't realised that over 300mb of camera/lens profiles had switched from Program Data (LR3) to Program Files (LR4b). That made the real difference about 400mb, almost all of which is attributable to the 200+mb of Book Templates and the almost 200mb of stuff seemingly video related (in the Support sub-folder).
There's also ... C:\Users\<username>\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0
As I understand it, that's the place where user-generated profiles should go. The location you mentioned, is for application's "stock" profiles.
That's the place to be! Thank you.
@Dorin: in "Users\etc.etc." I only see a file called "pscache.dat". It might be so that this is the folder to place user-generated profiles, but the ones I "downgraded" work and are accessable in LR4. What should be the advantage of storing them there? And isn't pscache only ment to be used bij Photoshop?
Well, user-generated content should be in the user profile folder. That's the way it should be in Windows (and other os's I think). For example, if you install a new version of LR itmight go into a different program folder and it will not see your profiles. But it will continue to see those from your user folder.
Lens profiles are shared between Lightroom, ACR and Photoshop's lens correction plugin.
That makes it clear and official.
But... the downgraded lenses are not visible in Photoshops Lens Correction filter. So I will have to copy them to the PS lens folder. Eh, where can I find it?
(I have a new computer so have to install some things and find my way in windows 7)
