re: #4 Randall Gross
No, I don’t think a mixed race couple would qualify for the “I don’t feel competent” argument. A wheelchair? Well, I can see where someone might not be able to capture what the couple had in mind. Of course, there are tons of totally incompetent photographers out there, so who knows.
The “some poses don’t work” is something I read in a piece by someone who plans same sex (among other) weddings. I have no actual knowledge of the situation.
In case it wasn’t clear, I was not supporting the idea of a photographer refusing to do a same sex wedding, merely that I had read that there could be issues. I think it’s always a good idea for someone who can’t do a job properly to admit that fact up front.
