A quote from Timothy Allen: "Put simply, the shorter the interval between each frame, the more slowly the action will move in your film. Using the shadows and clouds example again – clouds will almost definitely tend to move much faster through the sky than a shadow cast by the sun will move across a landscape. So, we normally set a shorter interval between shots when time lapsing clouds, and a longer one when shooting the sun’s path across the sky." http://timothyallen.blogs.bbcearth.com/2009/02/24/time-lapse-photography/
Before posting, I read that, and this: http://en.wikipedia.org/wiki/Time-lapse Being new to this, I imagined that focal length would play into the equation somehow. That's why I asked about "relative movement of subject in the frame". I imagined the end result would appear jagged/jerky if the relative movement of the subject across the picture was too fast. Tim Allen recommends to decrease shutter speeds to introduce some blur between the frames, but I imagined that the optimal shutter speed for a given speed of subject movement would vary with focal length as well... Perhaps I'm just thinking too complicated... :-) Jostein 2011/1/18 Cotty <[email protected]>: > On 18/1/11, Paul Stenquist, discombobulated, unleashed: > >>Yes, but if there's through-frame motion involved, it will also make the >>finished product look somewhat ragged, and at some point, it becomes >>more of a slide show than time lapse photography. > > Ahh, you guys are talking about viewing rate?
