JB do you use any filters?
Not really, I've experimented with a few but never really found much practical use for them in the type of photography I do. I understand the results of using one can really be great though, I may have to pick up a few if I ever find some that I like. It seems like the colours in some of my photos appear as though I am using a filter, though; this shot was done with no filter, freehand through a parking garage railing:
I still can't really figure out where the gold tint came from, there's no yellowish lighting at the terminal at Dulles. Some of the other pictures I've taken came out with more of a white colour.
