Got a polarizing filter for my camera today. WOW! What a difference it makes taking pictures in the midday sun!
Have you ever noticed how washed out your pictures can look when the sun is high in the sky? It's a really bad time to take great pictures. Anything that reflects the sun ends up to be blown out. And the sky looks white, rather than blue. A polarizing filter is supposed to help with that.
Look at the difference:
