What are a photographer's primary activities?

Photographers take photographs. They could be portraits, landscapes, photojournalism, fine art, etc. In order to earn money;photographers must sell their photos, so they work in sales, too. Also when they aren't at work they still do work like retouch pictures, or talk to new clients about setting up a shoot, or even just hang out. Besides the ones already mentioned above there are all kinds of other Specialisations Photographers can specialise themselfs in, to name a few; Fashion Photography, Advertising Photography, Medical Photography, Industrial Photography or Photographing Homes and Buildings for real estate Companies for example.
