Optical Red Filter (25A) on Digital

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 a m43 camera. 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.

nvm.

Thought auto exposure would take care of +3 exposure with 25A but it didn't. So those pictures are overexposed. When corrected to -3, it works fine.

Given that you can do all that in post I'm not sure why would want to use a colored filter with a digital sensor.

Just messing around em.

Your exposure was off because the meter sees primarily green light, so as far as the meter was concerned it was seeing relatively little light and reacted by jacking the exposure up. Orange passes more green so the meter was less FUBARed.

Try shooting under red LED lighting in a club some time and see what that does to your meter.
