Incorrect Profile Corrections Lens listing After editing in Denoise

[#1]

After sending an image to Denoise and then enabling Profile Corrections, the lens I used does not show up. Several other Canon lenses are listed but not the lens I used. Any ideas why?

Most lens profiles are for RAW only. The image from your external edit in Denoise is not RAW.

The File that was Returned to LrC from that Denoise program is more than likely a TIF file and Not the original RAW file.

So You can't apply a Lens correction in LrC for a TIF file.

Thank you for the answers. That makes sense.
