Filter for Portraiture
 

I want to get a filter for my Nikon 85mm 1.8 and I am going to use it mainly to shoot portraits. What kind of filters is recommended to get a nice warm look?

Maybe a normal UV lens is good enough, and photo shop the warm feel afterwards? =P

I've never bought a filter before, so this this will be the first time.

UV filters are useless on digital cameras, as digital cameras are not sensitive to UV light. You can just add a warm tone in post production.

I guess I will save myself some cash by not buying a UV filter.
