One of the things I like about being a wedding photographer is that I'm not doing the same thing all day. We shoot portraiture, clothing, shoes, fashion, tabletop details, and even architecture and landscapes, but we shoot photojournalism through out the day.
Photojournalism usually means documentary images that tell a story. Black & White is a good medium for telling a story, but color Photojournalism has its place too.
While some couples say they place more importance on Photojournalism, they almost always want Portraiture as well and choose a lot of portraiture for their albums. Couples who say they value the Portraits more do the same; They choose a lot of Photojournalism. We're happy to emphasize either, but our experience has been that couples and families are happiest when they have a combination of both.
I'll add a Portrait and a Details post soon.
