Orange is the 'medium' of the contrast filters for black and white photography.
Milder than red and stronger than yellow, it completely eliminates ultraviolet, darkens blues and greens and is excellent for telephotography of mountain and marine scenes.
Available in most sizes.

This is a great filter for black and white photography. I used it to shoot city scenes and it produced just enough contrast for all of those gray buildings and pavement. I especially like the fact that it's double-threaded, so I can use it along with a UV or skylight filter. And I don't have to open up as much, risking motion blur. A good buy.
