I am having a vignetting issue with my D800 and 80-400 zoom. The body has an in-camera vignette control, as does Capture NX2. My question is, should I use the in-camera vignette control or wait and apply the control in Capture NX2? Thanks in advance for any help here!
I am a Canon shooter but I would not expect that the vignette control has any effect on the RAW file and a little digging just confirmed that fact. Therefore, there’s no real advantage to doing it in-camera unless you do all of your conversions with Nikon software and just want the convenience of having it applied by default to the images shot with the feature enabled. In other words, if you are shooting RAW, the resulting image will be exactly the same whether you enable it in-camera or perform it as an explicit step during RAW conversion. There is no penalty for doing it after the fact. Setting it in-camera just sets a flag in the metadata that triggers Capture NX2 to apply the effect by default. Other RAW converters will likely ignore the flag since even if they knew where to find it, they would not have access to the Nikon algorithms for implementing the effect.
This is the same as any of the other camera-proprietary features, e.g. Picture Control. The only time it really matters how they are set in-camera is if you are shooting JPEG.
