    Lens distortion done in camera  in NEF - will Lightroom recognize this?

    justinw86398615 Level 1

      As per the title really.

       

      On a Nikon D7000 (and other cameras) you can set it to correct known lens distortion in camera.

       

      If I then open such a nef in Lightroom will this be recognized?

       

      Thanks

          Probably not. Many of these features only work in the manufacturers own software and are ignored or have incorrect results in LR, which is not he fault of LR. Lens corrections are built in to LR when using NEF files in your case, to correct barreling and pincushioning etc.

            NEF files are not "image" files, they are raw data files. Any proprietary info that Nikon adds to the raw files will not be read by most (any?) third party apps.

             

            If your camera is shooting JPG files, Nikon will bake the Nikon lens corrections into the image inside the camera.

             

            For raw files, the lens corrections need to be applied after the raw data is interpreted into an image.

            Nikon's software will use the Nikon interpreter and apply the Nikon lens corrections if requested.

            Adobe's software will use the Adobe interpreter and apply the Adobe lens corrections if requested.

              Thanks. Good point about the jpegs.

               

              For the raw data then what you seem to be saying is that the file which is downloaded from the camera is raw data + some lens correction information, but it still requires an interpreter to turn that into an image file. If I import the nef into the Adobe world it will ignore the lens correction information (the Nikon lens correction information applied in camera) and create the image without this?

               

              I will of course do some tests for this but it is useful to get a good theoretical answer.

               

              Thanks again

                The actual lens correction data is not included in the NEF file, just some tags about what lens was used.

                Using these tags, Nikon's software applies the Nikon version of the corrections; Adobe applies the Adobe version of the corrections. These type of corrections get applied after someone's interpreter converts the raw data into an image.

                  This is correct. It is just metadata attached to the raw file that is ignored by anything but Nikon software. The raw file is just that - the raw data from the sensor and some shooting metadata (including a built in jpeg preview). It is also used by the camera to create the jpeg preview inside the raw file, but Lightroom doesn't use this jpeg except for very initial display of the image in the import screen and before it has a chance to create its own preview.
