My contributions to Wikimedia, so far.
A handier gallery of the photo contributions I have made.
I live in Toronto, though I sometimes get to go on business-related travel and love to visit local museums with camera in hand. I'm the type that if I know I will be heading somewhere where there's a need for an illustrative picture on a Wikipedia topic that has currently none, I will make a point of going there with my camera.
My main camera is an Olympus Evolt 620, with an Evolt 510 and an Olympus EPL-1 as backup. Most of the pictures I have uploaded to Wikimedia have come come from the E-510.
I am also an intermediate user of PhotoShop, ditto Illustrator for SVG output.
