Here is an image of the city across the bay. If I recall I took this from a spot just below the Golden Gate Bridge. But I could be mistaken, it could have been from Sausalito, I'm not sure. Normally I use an app on my iPhone to geotag images so that I won't forget when writing about it later. In this case I forgot to do that or was just lazy. It doesn't matter that much, it's a picture, not a survey.
Speaking of surveys, I met a retired surveyor a few years back who now lives on a sailboat in Florida. He used to do arial surveying with a medium format camera. That's because back in the day's of film, the highest resolution images came from medium format cameras. Today that's still the case except everything is digital and hundreds of times more resolution. Anyway, the guy was selling his old Hasselblad cameras and lenses. The only problem was, nobody wanted to buy them. I think he ended up donating them to a film school.
So while I was here in San Francisco I was walking near Union Square and a photographer was setup in a mini street fair selling his prints. He still took all his pictures with a film Hasselblad camera. I told him the story of the surveyor in Florida and he understood exactly. Film photography is a dying art and the equipment, if you can find it, is dirt cheap. Of course, you still need to develop the film and process it in a dark room. And that, is something of a lost art these days.
Having said that it seems there is a small renaissance in film photography. I'm curious to see where that goes.
