I think Gavin Hoey is a great starting point for you. He has a wide range of videos covering various subjects like landscape, studio work, portraits and quirky things like water droplet and smoke photography. He is a great teacher breaking things down to be easily understood. He also covers the processing of his shots too. He likes flash and he loves the clarity slider!
He had his own channel but can also be found as a teacher with Adorama. I think its "take and make great photography" or something along those lines.
Also, if you're liking for processing/editing tutorials try Phlearn.
