Who says you need to choose?

I would bank on the niche name for short term, but keep a site up with the photographer's name for long-term... you might end up with even more -- and could use the "photog name" site as a hub with links to the niche site(s).

Chances are you can piggy-back the sites on a single shared hosting account for little or no-cost more than the cost to host one site.
