Does anyone know of an on-line source of Photoshop Lightroom 3 lens correction profiles for Nikon lenses? The just-released version of Lightroom 3 has a large list of Canon lens profiles but very few Nikon profiles. I know that one can in theory create one's own lens profiles, but I suspect that in practice it is not easy to create profiles that work as well as those in DxO or PTLens. Also - it appears that there may be online sources of profiles for Photoshop CS 5. Can these be imported into LR 3? If so, how can one access these PS 5 profiles? It is surprising that a very large company like Adobe cannot provide what a very small company like the distributor of PTLens can provide. Hopefully, someone will step in to fill that void by posting (possibly selling) accurate LR 3 lens correction profiles for all of the most widely used Nikon lenses.
