Filters for B&W LF - Where to Start?

[Alan Rabe]

Frank, you filter your water? And here I thought you were a real MAN.

Thanks for the crash course in filter use, everyone. This has been great.

I think the larger 4x4 square filter set-up (like the Cokin set-up) makes the most sense for me. And it'll be nice to have the option of using filters - for any future landscape work (a bit cold for that just now) it will be really educational to try one shot with a filter and one without...and see for myself.
