Is anyone into black and white photos? I'm interested, but need some tips. If you're experienced with this, then please send wisdom my way.

I shoot a Nikon D40x with a 18-55mm lens. It's the stock lens, but it does a decent job. I'm very interested in shooting Ansel Adams-esque high f/number shots. My lens has a minimum aperture of f/22-38, so I am limited by that. However f/38 is very small indeed and should be just fine for me just starting out in this endeavor. A tripod will certainly be used.

Anyone?
