How neutral are neutral density filters? I mean, would they work with infrared and ultraviolet photography the same way they work with visible light photography? Infrared photography is nothing new, so I hope this isn't something that's just been overlooked.

An ND filter should "pass" all colors of the visible spectrum equally. Its possible that some cheaper ones could "add" a slight tint to your image. That's why you spend the extra $$$ for a TIFFEN or HOYA or B+W filter.

They should add no color to the image, only reduce light. But there's been talk of some ND filters that aren't really "neutral." A reasonable question there is "how off" are they -- if they're not off by much you will probably not even know it.
I have a Sigh-Ray graduated ND filter and haven't noticed anything fishy about it btw..........

They come in many different intensities. As I recall, they are in .10 intensities. Usually they can be found in pro photo stores. Check on line first.
