James Duncan Davidson, the programmer turned photographer, was recently on The Talk Show, where John Gruber and Dan Benjamin asked him about digital photography, what lenses he uses, etc.

You may know Duncan from his work on the original Java Servlet implementation that went into Tomcat, his work on the ANT build system, or his more recent endeavors into writing books about Objective-C and Cocoa.
However, Duncan currently earns his living shooting at developer conferences - check out some with shots here: http://www.flickr.com/photos/x180/

If you have some interest in digital photography, listen to his conversation with John and Dan. Duncan shares lots of good tips during this 37 minute long podcast.
