Metering with a Polarizing Filter I just added a Circular Polarizing filter to my 17-50mm f/2.8 Tamron on my Canon 40D. Is there any need to modify the metering mode of the camera? Most of the time I'm using the Evaluative mode. Should I go more to a center-weighted mode? Or does it matter?

Hello Dan, I love my CP filter. I do quite a bit of waterfall/landscape shots, and it really helps with water reflections, the sky and allowing more detail of darker areas of a scene. I had a cheaper one but opted for the B&W Kaeseman polarizing filter, which isn't cheap but my thought is that I shoot with L glass and do not want to place a cheap optic over my quality lens. Since I am usually shooting a landscape scene, I use EV a lot (although I don't think it matters too much), but I also manually focus my lens and use a lot of DOF like f/22 or f/32 so that as much of the image is in focus as possible. I rotate the filter to where I like the look of the scene, then check my exposure and adjust for how the CP filter is affecting the exposure. I always use a tripod/remote shutter release and have lately been doing more multiple exposures for HDR imaging. Have fun Dan!

Thanks Carlton, I'm going to be on holiday next week in the canyon areas of Utah and felt like the CP filter would be a good tool. Mine is also a B+W as are all my other filters. I was just not sure if there might be a need to adjust the exposure metering covering the frame area. Sounds like that is not the case.

The short answer is that it doesn't matter at all. Your camera will compensate for the extra loss of light because it also meters through the filter.
