Just wondering what i'm doing wrong with my beach shots, trying to get some good water movement shots at the beach pools and not having much luck, tried sunrise, sunset and middle of the day. Getting great water movement (misty etc) but my whites are blown out. Don't have any kind of filters (i've been told I really need a polarizer), would this help? Also was out at sunrise this morning and tried to get the great sunbeams that were shooting into the sky but without success...... any thoughts??
