Technically none, Ive been a photographer for some time now and the most i dived into Portraits was family. Nature and wildlife and travel and landscape have been my go to niche's. I also enjoy some macro. But videos like this are what I look for. Portraits is my new adventure!
I really don't understand why B&H sponsors this photographer. He acts like if he invented photography but his pics are average. Worst 56 minutes wasted in my life.
