Robert Scoble recently recorded a spur-of-the-moment interview with the founders of Twitter. As he notes in his blog post, some folks are giving him grief for not using a “professional” camera, but he notes that the meeting wasn’t originally scheduled to be an interview.
He got the video because he had a video-capable camera with him at all times. Have you ever missed a photo opportunity because you didn’t have a camera? I always recommend that photographers have a camera with them at all times.
Carrying a DSLR and lenses and other gear all the time isn’t practical for many, but even a relatively inexpensive point-and-shoot camera can take some great photos. I have a Canon A540 with me all the time for opportunities to shoot when I don’t have my 40D. When it comes to getting the shot, a $150 5-megapixel point-and-shoot is far better than nothing at all.
