I have a question about using the lightroom lens correction profiles for cameras other than full frame.
I have been using a Tamron 24-70 which is known for having slight vignetting (full frame only) and the normal optical skews at certain points in the zoom.
The reviewers have always said that the better part of that lens is right in the middle and frankly I can see that for myself.
I applied a lens profile to an image in LR that had no vignetting and it underexposed the edges around the photo so it leads me to think that it just applies the profile to the whole image regardless of crop factor.
My question is, could this have a detrimental effect by say warping the DX image into something even worse that what it was before, just because it expected deficiencies in other places (due to the full frame profile)?
