180 degree shutter
on May 21, 2011 at 8:35:33 pm

I was reading this blog (link below) about 180 degree shutter. I understand the principle now, but my question is: Does this mean I should never change my shutter speed if I don't change my fps speed?

If I am set up at 24 fps & 1/48 shutter speed - the only things I should be changing are ISO & aperture?

Any feedback would be much appreciated.

If you're after the so-called film-look, 24p with 1/48 are the way to go.
With the shutter-speed you not only change the brightness of the picture but also the motion-blur. Faster shutterspeed = less motion-blur = more "strobing" motion.

If you want to maintain a constant look throughout your clips, don't touch the shutterspeed but change the brightness with the help of ISO, aperture or nd-filters.

A general rule of thumb is: Shutterspeed = 2 x fps

But: Playing around with shutterspeed can be a creative way to change the feel of a film. If you think about "Private Ryan" or the battle scene in "Gladiatior" (to take the best known examples), they are shot with higher shutterspeeds and have a kind of hectic feel about them.
