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.

This Week in Photo (TWIP) with Frederick Van Johnson

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.
