orange filter

<p>Hello, I am new to photography and new to this net. I was given an orange filter which was attached to the M6 camera. What is the purpose of this filter and when should it be used?Please help. Thank you</p>

<p>There's two types of orange filters.<br>

One is the color correction type, normally in the Wratten 85 series. These are used to use color films balanced for tungsten light in daylight. If you're using newly-manufactured color film, such a filter would be useless, since no tungsten-balanced color films are made anymore. (Studio lighting is now uniformly either electronic flash or LED, both of which are daylight color temperature.)<br>

The other is a "contrast" filter for B&W film. It makes subjects that are blue or blue-green darker. It would be used in B&W photography to make skies darker (to provide more contrast with white clouds), and to make foliage darker. A Leica branded one would probably be labeled "O" or "Or". Ones from Japan are normally labeled O56. The Wratten number would be 21.</p>

<p>Dear Bob. The orange filter can be used in many occasions, for example, to dramatize the sky, with white clouds in a blue sky, when you are using a black & white film. The action is between yellow filter (softer) and red filter (harder).</p>

<p>Welcome to P.net,<br>

John and Juan have it.<br>

Even the color correction type can be used, of course, for darkening the sky and other B&W film effects.</p>

<p>The color correction orange filter will generate much less contrast on B&W film than a proper orange filter.</p>

<p>It can also be used to make color photos orange.</p>
