I use a Pentax K10D and resize/edit in Photoshop CS on a MacBook Pro. My photographs are 98% people or animals and are from places from Southern California to Hohoe, Ghana.
I take pictures at pretty much any event I happen to come across.
Update: My camera and laptop were stolen in a burglary at our house! I now use a Pentax K20D and resize/edit in GimpShop on a Windows desktop built by my husband.
