Some posts ago I wrote about lighting tutorial slideshows by David Berman and Dave Hill’s works and his behind the scenes photos.

Today I came across Dave Black’s Website and the huge amount of workshop materials he published. Many, many great sample photos with detailed explanations on how he captured them. They are very useful whatever level you are in photography.
My personal technical favourites are on how to use remotely controlled Nikon SB-800 speedlights to light your subjects here, here and here.
But the most meaningful one at this moment in my life is the Principles of Success full of good pieces of advice for beginner - and not only beginner - photographers.

His pictures are copyrighted so I could not post any of them here.
