For this project we had the put the camera settings at ISO 100 and we put it on bulb mode which left the shutter open as long as you need. We had to point the light at the camera and the camera would then pick up the light. If you point it in the background, the background will show more.. Hard designs were the hardest to show up because we couldn’t see what we were drawing. the most frustrating thing was when the light would n’t be directly pointed at the camera and the picture wouldn’t turn out good.
