Our first tutorial is kind of required viewing so see this first! http://www.youtube.com/watch?v=SsViAv...

We reveal a couple of more techniques - basic masking, adding glow to blend flares into the environment better, and basic shells.

MOTION BLUR SHUTTER ANGLE CONVERSION

Frame rate is how many frames per second your camera records. Shutter speed is how long, in seconds, those individual frames are recorded at. So if you shoot 24 frames per second, the maximum your shutter speed could be is 1/24th of a second.

Here's the shutter speed/degrees conversion for 24 frames/second (or 23.98 frames/second):
1/24 = 360 degrees
1/48 = 180 degrees
1/60 = 144 degrees
1/100 = 86 degrees
1/200 = 43 degrees
1/500 = 17 degrees

Here's the shutter speed/degrees conversion for 30 frames/second:
1/30 = 360 egrees
1/60 = 180 degrees
1/100 = 108 degrees
1/200 = 54 degrees
1/500 = 22 degrees

Or use this formula:
(Shutter Speed) / (1/frame rate) * 360

So for above, if we're shooting 1/60th of a second at 24 frames per second, it would be:
(1/60) / (1/24) * 360 = 144 degrees
