I do a lot of photography. Photography can be extremely cheap. Current gear is of incredibly high quality; a camera can stay relevant for over 10 years and lenses, forever. If you buy a camera for about $1000 every 5 years that's $200/year, less than $20/month. And you can certainly buy cameras less often than that.

Then storage, software costs, while not exactly zero, are negligible.

Printing can be expensive if done well. But I've found, nobody cares about prints (except maybe the photographer).
