I listen to lots of photography podcasts. I have just come across the Road to Full Time Photography Podcast. You can check it out on iTunes here.
The host is Jordan Younce, and this is his website. He photographs buildings. As I do.
But the podcast is about more than photogrpahing buildings.
The podcast is up to episode 7 - check it out. Episode 2 offered some great advice on blogging.
