Without speaking for Cris, I suspect the problem may have started when you asked if he shoots weddings in a studio. The implication from my perspective was that you thought he's "only" a wedding photographer with no studio experience, and doesn't really know what he's talking about with regards to a studio, i.e. you were calling into question his experience. If that's how I interpreted it as a non-involved 3rd-party, I can only imagine how much more magnified the (unintended) insult might have come across to Cris. That's why you got a studio picture posted in response.
