My earlier digital pictures were taken with a Ricoh RDC-4100.
Everything after December, 2002, was taken with an Olympus C4000Z.
Most stuff from October, 2006 forward is taken with a Fuji FinePix4400, which I ruined by getting it wet at Disneyland in October of 2007.
From November,2007 for about a month, I used an Olympus Stylus 1000.
I returned that and bought a Canon PowerShot A720, which I hate more than the Olympus.
In September, 2008 I bought yet another new camera, this one a Canon PowerShot SD1100 IS, which I like very much. All of my pictures after that date are taken with it.
