    Posted this on POTN also.

    Have you played around with 25A on your digital camera?

    I was testing for a stronger contrast in skyline so I slapped on a 25A - red filter on e-pm2. See these pictures.

    1. 25A color picture
    2. 25A converted to B&W
    3. Orange Filter converted to B&W

    Is that what you'd expect? Does digital sensor not work with red 25A filter? Orange filter works well. 25A doesn't.

    It looks very over-exposed to me. You might try metering without the filter and manually adjusting. If I remember correctly 25a is +3 stops.

    Holy crap you're absolutely correct. Set it at -3 and the B&W conversion looks good!
