Bridge Time | Photoblog 2.0: "First I did some tests at 30 seconds to get the exposure right. My plan was to multiply out the exposure time once I had the right f/stop at this shutter speed (the maximum I can set on my Nikon D200 before going to Bulb). Based on what I was seeing in the LCD after exposure, 30 seconds and f/5.0 seemed about right.

Based on the 30 second exposure, I calculated that at f/22, the most stopped-down (smallest opening) of the lens I was using, 8 minutes would be about right."
