not over exposure man..its an extended exposure. over exposure is when the f stop isn't adjusted correctly and either to much or to little light is let in
An extended exposure can result in an over-exposure..
But yeah, your shutter was definitely left open way too long.. was it really dark out or something? Maybe your camera was on aperture priority or something..
alright, i was messing with his camera. I turned the dial on the top and then hit the button and it made a wierd noise and a light turned on and then i hit the button again and thats what happened. It resulted in a sweet picture... and i dont know where those lights came from because it was really dark out
