San Francisco is a great place to live -- and photograph. I shoot the City daily and have been for several years. While I mostly shoot w/ compact 35mm cameras, we've got some LF shooters out here as well!
I wish the fellow in the Petapixel engaged with the street and people more. Shooting SF with a tele is not necessary. Most street widths work great with a 35mm or 50mm. His "edit" of 301 final images could use a few more edits. Asking someone to look through 300+ photos is a tough request.
