Today I took some pictures, mostly RAW, but a few JPGs. Lightroom 4.1RC, Windows 7 64bit
When I use the Lens Correction feature on the RAW photos, the proper lens is selected, a Nikon AF-S NIKKOR 16-85mm f/3.5-5.6G ED VR.
When I use the Lens Correction feature on the JPG photos, the proper lens is NOT selected, instead I see it has selected a Nikon AF-S DX NIKKOR 14-24 f/2.8G ED. In fact, next to "Model", I cannot even select the proper lens (the 16-85mm lens) because its not in the list.
How do I fix this?
It is not in the list because it is perhaps not available. I guess you have
forgotten that the lens profiles are specific to file type.
You need to hack (use Notepad) a "raw" profile to get one for Jpeg.
Where are the lens profiles located? or what is their file type?
The lens profiles in LR4 are located in "C:\Program Files\Adobe\Adobe Photoshop Lightroom 4\Resources\LensProfiles\1.0\" and have an extension of *.lcp.
If you want to tweak a Raw profile to be used by JPEGs, you need to
I did the edits to change the RAW profile for Canon 5D Mark II with 16-35 f2.8L II into a JPEG profile. It now shows up in the list, but doesn't seem to change the image at all when selected. Other profiles in the list do change the image when selected. Does this conversion process really work or what did I do wrong?
If the profile shows up in the list, you did the right changes. As to why you don't see any changes, I can't really tell you too much. You'd have to play with a Raw and a JPEG image from the same camera/lens combination and see what the raw profile does. One reason might be that some lens correction has already taken place in camera (although I'd then expect the correction to overdo on a JPEG).
I don't think the 5D Mark II does in-camera corrections, although I'd have to do some research on that.
It does have vignetting correction, which is based on uploadable lens data.
