I've been thinking about buying (in a hopefully near future) a Nikon D80. While looking at the specs it talks about "In camera B&W filters" such as red, Skylight and warming filters. I currently own an Olympus E-300 and i know that the E-500 model has these "filters" as well. Is anyone familiar with this? I know it does not compare to the real thing and I know is most likely a "digital interpretation" of what a screw-on filter would do but, do they really work? .
Thank you for you help.
Tony
