I just got a polarizer and I am trying to figure out what can I use it for. I noticed that it darkens the sky, steals a lot of
light, removes reflections from glass, water and some shiny objects like cars, from some objects even indoors under neon light,
darkens the LCD to black. :) Can I use it with flash in some usable way ? What If I put a second polarizer over the flash ?
Does it affect contrast ? How about snow ? I did not try to shoot any pictures yet, I am just trying it first without the camera to see what it can do.
As you noted, a polarizer is useful to reduce specular reflections. That can have the effect of increasing contrast and saturation, darkening skies, and improving tonal separation in foliage on a sunny day. It has little applicability to flash exposures.
I use one occasionally, and most particularly when copying flat art to minimize reflections.
