hey guys, i'm looking for some shutter speed suggestions for a certain shot.... i want to capture a cityscape at night with a slower shutter to get headlight traces and then speed it up in post.... has anyone done this shot? if so, any suggestions... i'm new at playing with the shutter speeds and i want to up my game... thanks
Depending on how fast you intend to speed it up, you may want to take a series of photographs instead of shooting video.
To get a nice fluid look in video or film most go for 1/(2xfr rate) for shutter speed. So if you're going for shooting at 30fps you'd normally want 1/60th shutter speed. This is the 180 degree shutter rule, that the film is exposed for half of the time of the frame.
Thus, if you're going to try taking photos you could try taking perhaps a 5s shutter picture, waiting 5s, taking another one, and so on, and putting them into a project, giving each image one frame of time?
I'm sure there is a perfect mathematical solution but my mind is much too boggled to realise what it is!
