Polarizing Filter - Light Loss? The information I have on polarizing filters says that as they absorb light, you need to change the f/stop to compensate for that. In automatic modes, does the camera know there's a filter and do the compensation, or do you need to do it manually? Thanks

SLRs and DSLRs use through-the-lens metering for their auto, semi-auto, and manual modes. The light loss from the polarizer is taken into account automatically. If you are using a separate meter and setting exposure manually, that meter does not see the reduced light through the polarizer so you have to adjust the exposure given by the meter.

Thanks Jon, that makes sense! I'm starting to use some of the modes other than auto on my D50, but am not using a separate meter at this point.

With spotmetering mode there is no need for separate meters.
