I've come across something that is odd to me. I have some TIFF files created in an HDR program and the files do not have have the lens information embedded in them. In the Lightroom (version 4.4 on Win 7 64-bit machine) Lens Correction panel, when I enable Enable Profile Correction, then enter the camera make (Canon) and select a profile from Model drop down menu, the only profiles that are available for selection are ones that I have downloaded via Adobe Lens Profile Downloader (and which are stored in C:\Users\(User Name)\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0 C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0). This, of course, is the oddity. Thus the extensive list of profiles that would 'normally' show up in the drop down menu in the case of a CR2 file are not available.
My questions are:
> What is causing this?
> And how do I 'overcome' this so that the full list of lens profiles is available for me to select from?
Thanks for your help.
