Going through the polarizer learning curve
So I was in a parking lot at Big Bend National Park, eyeing some spectacular mountain formations. I shot some with the D700, and then decided to get out the 52mm Nikon polarizing filter that has been in my bag since 1989. I put it on my 50/1.4 Nikkor, added its dedicated hood, and shot a few frames on Aperture Priority. Then I ducked into the shade of the 4runner to check the exposures.
Nothing. I got a black frame. So I switched to manual exposure, opened up two stops, and tried again. This time the exposure was not bad at all. One minor correction, and I was on my way to some pretty nice shots.
But I need to know why the D-700 didn't give me the right exposure on aperture priority. I recall that some years ago circular polarizers came out, and this was required for something: autofocus, or (apparently) in-camera exposure metering. Or both. Is that it? I just need to buy circular polarizers for my various filter sizes, and the camera will meter correctly? Or am I missing something?
May the light be with you.
