Do you still use filters, or do you do everything in post processing? I'm using a K2 yellow filter for black and white landscapes for non-digital work and have two Neutral Density filters giving me a 2 and 3 stops reductions which results in an even smaller depth of field or longer exposure.

I agree with Jackal, but for now I have no other choice than doing stuff in editing mode. But, once I get my hands on some good filters, I will have fun-fun-fun!!
