I have used several different cameras during my fieldwork.  Things routinely break or "disappear", and I seem to upgrade equipment more frequently than perhaps I need to.

Some of the earliest videos were shot using a Sony DCR-PC110 Digital Handycam together with a 12 volt SunCatcher Expedition solar panel to recharge the batteries. I later bought a Canon ZR 600 Camcorder and have been quite happy with it.  Smaller, lighter, and does fine except in really low light. Moving further in this direction (perhaps too far), I recently ordered a Flip Mino to stuff in my pocket. Depending on the complexity of the video and my level of enthusiasm, I use either iMovie HD (v.5) or Final Cut Express (v.3) to edit the clips.

As for still images, I use a trusty Nikon Coolpix 8700 and have recently acquired a Nikon D60 SLR. I like the image quality and lens capabilities of the D60; the portability and tolerance of the Coolpix are hard to beat. Images are stored and managed using Adobe Photoshop Lightroom (v.2).  Adobe Photoshop CS3 is my preferred tool for cropping and tweaking and whiling away the hours.

"thus i have seen" is produced using an old, somewhat dented, 12-inch Powerbook G4 and Squarespace v. 5.  I wouldn't trade either of them. [Full disclosure: I just bought a new 13-inch aluminum MacBook.]
