Yep. You'd be fine with colour film, but b&w is significantly less sensitive to red. The orange filter is eating a stop of light for its density and requires another third of a stop for the proper exposure on b&w film. It's just like shooting b&w under tungsten lights, where you have to open up a stop (or more) from your metered reading to get the right exposure. So, either use a hand-held meter and change your ISO to reflect the 1 1/3 stop difference, or put the filter on the camera and see what the camera's meter reads and then dial in the difference between that and the filter's rating (in this case, overexpose by an additional 1/3 of a stop). -Aaron - This message is from the Pentax-Discuss Mail List.
