My general feeling about equipment is that you use the gear that best fits your vision.  For some that may mean purchasing a trunkful of lenses and gadgets.  For others it may mean an oatmeal box pinhole camera.  I work in 35mm, 120 and large format 4x5, and in Black & White and color to achieve the results I need for a variety of work.  Why is so much photo equipment black?

35 mm Camera Equipment

Nikon N70 body, Nikon FM3A body, the following Nikkor lenses - 18-35mm lens, 28-70mm lens, 70-300mm lens, SB-26 flash, Cokin graduated neutral density filters, Tiffen slim polarizer

120 mm Camera Equipment

Pentax 645 body with Pentax SMC 45mm and 75mm lenses

4x5 Camera Equipment

Toyo Field View 45A Camera (a real workhorse), 90mm Caltar Lens, 210mm Caltar Lens, Lee 3ND and 6ND Graduated Neutral Density Filters, 81A Warming Filter, Polarizing Filter, these Tiffen glass filters for B&W - #11 (green), #12 (yellow), #15 (orange) and #23A (red), and a Wratten #58 (dark green) Kodak Filter (100mm x 100mm) for B&W (used extensively with sandstone to separate tones and any light salt stains on the rock)

Manfrotto O55MF3 Magfiber Tripod with Manfrotto 488RC4 head (holds the 4x5 just fine and saves my back!)

My preferred color films are Fuji's Velvia 100 and Provia 100 for daylight color work and Fuji T64 for studio work.  My color film is processed by Photocraft Lab in Boulder, CO and Brian Parkin Photography here in Moab.

I use a small array of films for B&W including Ilford FP4+ and Kodak's Tri-X, Tmax 100, Tmax 400 and Tech Pan.  I hand process all B&W film using Kodak HC110 for most sheet film and D-76 for most roll film.  I use Ansel Adams' Zone System as a basis for film exposure and processing.

Digital Processing

Photoshop CS2 on a Mac (of course!), Lacie Electron Blue IV Monitor, Epson 2200 Printer, and usually Moab Paper's Entrada 190 paper.  Petroscans of Moab, Utah does most of my film-to-digital scanning.
