Scott Kelby is one of the world's leading publishers of photography books and video. He produces an hour long podcast each week called the Grid where he and studio guests discuss photographic issues of the day, critique photos, offer tips and thoughts on new kit, websites and other matters of interest. I generally watch it on Fridays, but it airs live on Thursday evenings GMT.

Serge is a French photographer living in Paris who has produced a series of free YouTube videos around post-processing in Lightroom and Photoshop. Well worth a watch, as are his paid video collections too! I've learned a huge amount from his weekly free podcasts - this is one of the best resources out there to learn retouching skills.
