I listen to a lot of podcasts. That's all I do while in the car. Here is a list of all of the photography podcasts to which I subscribe.
I also have a few favorite vlogs that I listed below as well.
The PetaPixel Podcast - this is a great photography news podcast. Stay up to date while being entertained by host Mike "Sharky" James.
The No Name Photo Show - Sharky James and Brian Matiash
The Family Photographer - I was on her show when she was still on TWiP. Read it here.
Mirrorless Minutes with Jamie MacDonald and Mike Boening - Two Olympus Visionaries sharing their experience and photos every two weeks on this live broadcast video show.
The Candid Frame with Ibarionex Perello
The Digital Story with Derrick Story - this show airs every Tuesday. Inspiration, gear talk and news. Great companion website as well.
Improve Photography with Jim Harmer
Vlogs I love:
Joe Allam - He talks gear, he talks travel and he even throws a review in here and there.
Peter McKinnon - I cannot tell you how much I enjoy watching this guy. His video work is nothing short of amazing and his philosophy inspires me.
Panoptic Chopsticks - these guys are a hoot. They put out a lot of educational content. Fun to watch.
