I can only take credit for one of these pics. These are pics of a storm that we drove through on the way back to our campground in the Badlands of South Dakota. The really interesting thing about these are that they were taken by my wife, using BULB exposures, through a car window, with NO TRIPOD, while we were traveling at 60MPH!!!! I can't believe how little camera shake is in the pics given the circumstances. All of the pics were taken using ISO-400, f/8, and bulb shutters until the bolts popped up. Shortest exposure time was 8 seconds and the longest went all the way to 37 seconds. The last pic (the one I took) was taken using a tabletop tripod using bulb exposure for 14 seconds at f/3.5 and ISO-400.
