To help students use this rig quickly and effectively, I created this cheat sheet card. This cards are attached to each of the cameras and help students quickly recall how to change shutter speed, ISO, and aperture to achieve the look they want.
*Note: We no longer use the small audio box but rather the Zoom H5 audio recorder.
Aperture is an element in a camera that closely resembles the iris in our eyes.
The aperture controls depth of field in a picture, which means:
how much distance or how little distance is in focus.
The aperture controls whether:
> A few inches in front of the lens are in focus
> If everything in front of the lens going back miles and miles is in focus
Aperture also controls how much light enters the lens and hits the sensor.
Meaning, the aperture effects exposure (bright and dark).
How does this connect to the human eye?
Have you ever gone from a dark movie theater out to a bright sunny day?
Cameras are not as smart as human brains, and cameras do not automatically adjust the iris unless set to an 'auto' mode.
Cameras & Aperture
Light enters through the iris / aperture of the eye and then hits the rods and cones at the back of the eye. This makes an image in our brains.
Looking through a lens, the image appears upside down just as it does in the human eye.
Short Answer: Lenses bend and refract light.
Depth of Field
How much physical distance within the image is in focus.
The aperture setting determines how much physical distance in an image is in focus by altering what light rays enter the lens and how they are bent.
