I bought a Canon Powershot about a month ago to take with me on my first supported bike tour. The darned thing is downright addictive! I shot probably 500 photos that week. (I jettisoned the lousy ones every evening to give me plenty of room on the memory card.)

I, too, wanted to take at least some pictures on the move, as well as when I was stopped. I found it to be doable but tricky. My set-up included a compact and very stable Ortlieb handlebar bag that allowed me to keep the camera within easy reach. I tucked the camera into the top third of the bag, down far enough so that it couldn't pop out if I hit a bump.

Even with the image stabilizer, I found it tough to get decent on-the-move shots. For every one that came out well, there were probably a half dozen throwaways. It was also difficult to see the screen in glaring sunshine, so aiming was a bit of a challenge. AND, of course, safety on the bike was, ahem, compromised, too. I only took photos when I was confident that I didn't have any traffic creeping up behind me, or any potholes or other nasty obstacles ahead of me.

Have fun!
