I recently upgraded from a Nikon D3100 to a D600. The D600 has many more correction features such as Active D-Lighting, Filters, color tone, vignette control, Noise reduction, etc.
Is there an advantage to having the camera perform these manipulations rather than post shot in photoshop?
The only concrete advantage I can see is that if you are shooting JPEG and if the camera performs the manipulation before it is written as a jpeg, the edit is done before lossyness. However, if the camera corrects after it is a Jpeg, I can't see how it is anything more than a convenience feature.
I will need to look at the manual some more, I am guessing you can't even use these in RAW mode.
Additional Info - added after I posted question I just read a post by someone that claims that when you use "Long Exposure Noise Reduction", the camera will take two exposures and use the second exposure (with shutter closed) to spot and cancel noise as false data. I am guessing you can't really make a generalization and instead need to look at each of the process options and how they work. http://scottreither.com/blogwp/2012/07/01/nikon-d800-e-long-exposure-issues-problems-2/
