I love time-lapse photography. I’ve experimented with it a bit, with both iOS devices and various cameras. However, time-lapse really takes commitment. I’ve done this math on this blog before, but I’ll do it again. Let’s say that you’re shooting one shot every 30 seconds. If your video is a standard 30 frames per second (fps), then it would take 15 minutes for one second’s worth of video. One hour would give you four seconds. 24 hours would be 1.6 minutes worth. That’s not a lot.
However, for good time-lapse you need some persistence of vision. 30 fps is probably too fast. You could either reduce the frame rate, or you could decrease the time interval to something like once every 5 seconds. Either way it’s still a commitment in time.
Plus there are other factors to consider. If you’re shooting outdoors or on location you have to protect your gear from the weather and you need to keep it secure. There’s also the issue of power. Will your camera run that long on batteries, or does it need external power? It can be daunting.
