I recently order a new Canon 40D camera along with a new Canon 24-105 4.0 I.S. lense and I hadn’t had much luck with lightning shots so I decided to play around with some nighttime exposure shots. these shots are from around 15 minutes to around and 2 hours. I thought you would like to check them out.
This shot was about a hour and you can see how the camera lense picks up any light available… my yard light is what lights up the pasture behind the house.
