Marty’s photo of the day #4620: When I present my show, Around the World in 90 Minutes, at colleges, students often ask about the cameras I used. I tell them that I started with film cameras and was 100% digital by the end.

Then I tell them how difficult it was to shoot platypuses in Australia, since my film cameras didn’t provide instant feedback. Because platypuses surface with little warning, I ended up shooting 6 rolls of blurry platypus photos. Well, technically this one isn’t blurry.
