Well the Fillmore had extensive work done after the early 90s quake, the Warfield had a big re-do (mostly technical stuff) this past summer including new carpets (at a cost of $1,000,000 - not cheep, but remember its like carpeting almost 1/4 of a city block).
Those are all shot using a Kodak 5mp camara. Nothing fancy. The trick, if there is a trick, is that you take 100 or so, perhaps even 1,000 pics to get the one good one. I used a Pentax K1000 for years before I went digital. What the digital gives me is that chance to take 100+ pics without going into debt for film and developing. And chance has a lot to do with it too, the right moment, the right light and all that.
The thing that is funny, or creepy, is that if I put up 50 pix on the Flicker, the first ones downloaded are the ones of graveyards.
