I’m planning a trip to San Francisco early in May and got some info from an SF visitors site. One of the ads, for an art gallery, said they had "Rock Photography." I couldn’t figure out what that was. Were they showing photos of rocks like this?


Or was it rocks like this?


As a former photographer I wasn’t aware of a rock photography genre. I finally Googled rock photography and found out it was photos like this! All depends on where you’re coming from, I guess.
