As long as the product you offer matches the description you sell to your client you can call yourself whatever you like.
I don't really care. Semantics
What I do care about is
you choosing some pretty interchangeable terms, adopting some university level descriptions as if they're immutable fact, and then arbitrarily deciding that
I really shouldn't describe
myself as documentary, but that
you'd be happy for me to use reportage.
You don't get to decide. As long as 40 couples per year are happy to book me at £1800+ on the basis of how I sell myself, and the photographs that I show support that description then I'm more than happy with the term 'documentary wedding photographer'. I have never had a paying client tell me my description is wrong.
So far I've seen you claim 180 weddings, yet with no website or anything to support that, simply picking a fight based on semantics. You know who I am, and how I term myself. It's there for all to see. I, quite frankly, have no idea who you are.
