Most of them are old. Some of them are seen before. A friend of mine ask me to sent him some pics he wanna use for a poster so I went over my old pictures again, and wanna share them.
Oh i get ya... so for the time you have the shutter open while taking a picture leaves a streak of light to the point where the shutter finally closes...
so if it stayed open as long as 3 seconds youll have a beam length of 3 seconds?
