Ten Tips for Recording Slow Motion Video Fstoppers

Tip #1: Understand Your Subject
Slow motion is all about movement, and certain subjects do not lend themselves to being interesting in slow motion. In other words, just because your subject is moving doesnu2019t mean it will look pleasing slowed down. A boat meandering through a canal from 100 yards away is probably not going to look very interesting slowed down. Conversely, splashing water on someoneu2019s face from 3 feet way could provide a unique take on an otherwise ordinary scene.
Tip #2: Select a Frame Rate
Most cinema is shot at 24 frames per second or the equivalent of 24 pictures compressed into one second. Virtually any DSLR will shoot in this format. However, if you dig into the menu, you may find your camera offers other frame rates such as 60 fps, or possibly 120. Spreading out 120 pictures at the standard playback rate of 24 fps will take longer to view than real time, resulting in a slower-motion image. Important to note here is that while most cameras will shoot at higher frame rates, this is generally at the expense of reduced resolution.
Tip #3: Think about Light
Shooting at higher frames rates requires a faster shutter speed to compensate, and, therefore, the sensor will not pick up as much light. The general rule of thumb is that you should set your shutter speed at twice your frame rate. Therefore, shooting at 24 frames per second requires a 1/50-second shutter speed, and shooting at 120 frames per second requires a 1/240-second shutter speed. Be careful, though: some lights types (such as fluorescent) appear to flicker when recorded at higher frame rates.”
