TZ12 – How to Use a Camera
We all know how to use a camera. You pull it out of your back pocket, flick it on, point and then snap the button; whereby a flash illuminates all your friends.
Now imagine if that camera took a picture every 1/24th of a second. The shutter speed, the aperture, and the gain would all have to be adjusted. Of course, if your pocket camera had an aperture, it would cease to be an ordinary pocket camera.
It would be a video camera, which is what this episode is all about.

At 24fps, use a shutter speed of 1/48th which is the equivalent of a 180degree shutter in a film camera. This is what we are used to looking at for cinematic movie making.
)…on a large screen, our Persistence Of Vision will cover the gap up for us.
The stuttery motion that you get when looking at fast moving things in the frame are alien in cinematic filmmaking, not due to the shuuter being slower to capture the whole timeslice, but because they have stringent rules about how fast a camera can move and how fast objects in the frame can move…there’s charts for panning speeds and everything out there. Your flapping (though really cool looking and a great demonstration of shutter speed) was far too rapid a movement to be allowed for video display (yes, breaking the rules is allowed, but you should know them first…as a rule
If your camera doesn’t shoot progressive (60i or 48i), then you’ll want to match the shutter speed to the frame rate. a faster shutter speed (higher numbers on the bottom of the fraction) can be used artistically to get a hyper real look (the beach on “saving private ryan” or the zombie attacks in “28 days later”) or slower shutters (smaller numbers on bottom of fraction) for getting that “drunk guy walking through party” look.
Thanks for all that info, Cole
