In order to improve my technique or find new ideas, I often watch tutorial videos on Youtube. Here are a few of my favorites:
Serge Ramelli is a French photographier living in Paris. He gives his best tips on how to use Lightroom and Photoshop to transform a plain photo into a great photo. Watching his tutorials made me change my way of developing photos. He also sells good Tuto packages on his internet site. His address is: http://www.youtube.com/channel/UCyaDDjiNgWX-uRXOx6LPsYQ
Karl Taylor shows how he "constructs" his photos. Whether they concern indoor or outdoor photography, his videos show how a professional photographier works to get the end result desired. His way of explaining photo compostion, lighting and equipment is an inspirational source for me, and for many others I'm sure. His address is: http://www.youtube.com/channel/UCZajtzLoD3nxn2G9ripCjPg
Kelbymedia Group is probably one of the most well-known photo training companies in the world. Some free videos are available, and there are others that can be bought. Their address is: http://www.youtube.com/channel/UCFJ7r70nIWRe0mJ2lp7NAsA
B&H Photo Video Pro Audio is a Youtube channel by the famous photo store in Manhattan. This place is a "must" if you're in New York City and you like photography. They offer some interesting conferences on Youtube. Their address is: http://www.youtube.com/channel/UCHIRBiAd-PtmNxAcLnGfwog
Like I said, these are some of my favorite addresses. If you know of any others, please feel free to share them...
