I would like o share with you two podcasts that I regularly listen to.
The first one is Secrets of Digital Imaging by Dennis Hays. It is a very interesting podcast for everyone new to digital photography or photography at all. I encourage you to listen to the podcasts from the very beginning. They are very educational. You can subscribe via iTMS or through this link.
If you know any other podcasts about photography that are worth listening please let me know.
