For my first serious effort at getting shots of Wishes, I'm going to try f/16 or f/22 from what I've read. Should I use the bulb setting on my XT to control the shutter speed (perhaps leaving it open for 20-30 seconds as recommended in one book) or just put the camera on aperture priority and let it choose the shutter speed? ISO will be either 100 or 200. I've got two nights in the MK for our upcoming trip to try to get this right. Thanks for the adivce!
