I am very happy with Alex's service, from the moment I started enquiring he responded promptly and with a lot of detail which ended up in me flying over to Koh Tao to spend a week under his tutelage. I arrived with a semi dated DSLR setup I had no idea how to use and instantly he had me comfortable with all it's bells and whistles and from the get go he had me taking much better pictures. Alex has an easy going teaching manner and a massive wealth of knowledge that he shares easily in normal jargon. He just seems to know where people are at and where they want to be and he goes to work to make that happen for them.
I would strongly recommend Dive4photos to anyone wanting to improve their underwater photography.
