The only lens profiles Lightroom shows are those that are JPG compatible, even though all my photos are TIF. My very first import had JPG files... perhaps this is why it cannot find my specific lens?
The metadata in my Library shows all the correct information – Nikon D750, 24-120mm f/4.0
Thanks for any help!
Adobe/LR supplies lens profiles for RAW files mostly. It's not that LR is treating TIFF's like JPG's it is because Adobe doesn't supply lens profiles for any other image files other than RAW.
You should do all the lens corrections, if needed and not Built In, on the RAW file before it gets converted/saved as a TIFF.
To my knowledge no camera uses the TIFF format for saving image files to the memory card. Even if there are those camera more than likely also record RAW data.
Ahhh wow!... this whole time I thought I had to convert the NEF files to TIFF, but I could just take them straight into Lightroom. I feel so silly. All the lens profiles show up now, thank you!
