I did a ton of these photos during sunset at Mile Rock Beach while in San Francisco. When I find myself in the right spot at the right time I go a little shutter crazy and end up taking dozens of photos. I'm going to reserve judgement and just say that's a good thing.
The Pacific coast is lined with these big rocks just off shore. I imagine that back in the old days there were shipwrecks during storms and now are historical sights to dive and explore. The two furthest rocks here are Lobos Rock on the left and Blackhead Rock just right of center. They must be well known to mariners.
I don't know why I'm so obsessed with the past. When I look at photos of a scene my brain looks for context, we all do that. So with a scene like this, or something completely different like the street scene from Barcelona I posted the other day, I take a step back in four dimensions. By that I just mean just naturally tent to view a scene or subject from a context outside the current moment. I'm not sure why I do that, maybe everyone does it and it's not unusual. I wonder if there is a name for that? Good, bad or indifferent it does open up a whole new world of perspectives, especially in my photography.
So there you go, time travel 101.
