Anyone can take a photography course and get a nice little certificate to show for it but making a name for yourself as a photographer means getting a body of work and actualy getting people to look at them. Some of the best pictures I have ever seen actually came about by experimentation and what you could call a happy mistake that came out looking interesting.
I think that if your friend got his work out there and worked at it he might make something out of it.
Just my opinion really I am nowhere near the class of photographer like we are discussing here, I just click away and hope for the best
