NPS PHOTOGRAPHY TEAM ARTICLE

The purpose of this demonstration is to show how you can get streaking in your photos, even if you are using your flash. You do not need a long exposure to have this happen.
The photos provided are a couple of shots I took with my iPhone 5s. I have included screen shots of the EXIF data from both photos. Notice how the exposure time is the same for both photos.
With the first photo, I held the phone as still as possible. In the photo with the streaks, I moved the phone slightly as I took the photo. It takes only a very light movement to cause streaking from any light sources in the distance.
If you are walking around outside at night snapping photos here and there, it is very easy to unintentionally have your camera in movement as you take a photo.
