Hello, I am planning on getting a Canon 20d w/ a Canon 24-105 lens. Right now I am busy researching what kind of filters I might need. So, to get to the point, I really admire this photographer on Panoramio. Here is the link so you can look at his pics: Panoramio - Photos by Andrey Jitkov And I would like to know what kind of filters he is using. Especially in his landscape shots. He definitely uses a polarizer filter and ND filters, but what on earth does he use, that makes his shots so bright!?? Any comments would be appreciated!
