Tools: These days I do all my imaging and image editing on Linux using open source tools. I do most of my photography now with an Olympus C-700, which has a long lens (good for birds) and a lot of flexibility and manual controls compared to a lot of the digicams; or with a Minolta DImage Xt, a very small and light digital camera which is easy to carry anywhere, though it lacks the flexibility of the Olympus.
Older shots mostly used a Nikon FG or Nikkormat EL and Ektachrome or Fuji slide film. (I'm never happy with print film, but the hassles of getting slides scanned drove me to digital. I really miss the flexibility of an SLR, though. I wish someone made a simple digital SLR back without all the unneeded bells, whistles, weight, size, and expense of the current crop of overdone digital SLRs!)
I have an Epson Perfection 2400 Photo scanner, which also has a slide attachment, though focus on slides is imperfect. I print on an Epson Photo 700. It's not that I'm a rabid Epson fan, but they do seem to make good products with open specifications, so they end up being well supported on Linux.
I've written some scripts to generate thumbnails, produce html pages, maintain image archives, etc. on my software page.
I have a fairly extensive, though probably outdated, collection of links to other photography-related sites.
