My Favorite “How to” Photography videos: Learning DSLR by Philippe Dame
I highly recommend this Youtube series by Philippe Dame, whether you are a full professional or just a beginner. Philippe covers the basics in simple compelling language that not only communicates the knowledge but also deeper understanding of the science and art of photography. Even professionals who think they know DSLR’s in depth will be challenged to think about how Digital photos are created in new ways, and some of these basics cover depths that some pros do not understand (e.g. Philippe’s explanation of how shutter curtain one and two affect exposure and timing is awesome.)
