Depth of Field Activity


Don’t forget to set focus manually for every shot! Write down the lens, shutter speed, aperture/f-stop, and ISO for each shot. We are going to set the ISO to auto but I want you to keep track of it so we can see how it changes based on the aperture. To see the ISO press the shutter half way down.

  1. Set Movie Exposure to “Manual”
  2. Set Shutter speed to 2x frame rate
  3. Set ISO to Auto
  4. Adjust F/stop accordingly
  1. Low = Narrow d.o.f.
  2. High = Deep d.o.f.
  3. D.o.f = Depth of field

*This is why lenses with a low f/stop are so expensive. They let more light in so they can shoot faster and have better control over the depth of field.

Station 1: 85mm or 30mm Prime Lens
Frame up a close-up shot of your subject. Make sure that you have plenty of space between it and the background. A good rule of thumb is at least twice the distance between your camera and the subject. Set the aperture as low as possible while maintaining proper exposure and shoot an 8 second clip. You should have a very narrow depth of field. Now increase the aperture as high as possible and shoot an 8 second clip. You should have a deeper depth of field.
*You should have at least two shots for each person at this station.

Shutter ________ |  Aperture ________ |  ISO ________  | Focus  | Movie Size: 1920 x 1080 24fps

Shutter ________ |  Aperture ________ |  ISO ________  | Focus  | Movie Size: 1920 x 1080 24fps

Station 2: 18- 55mm (Kit) zoom Lens
Zoom all the way out to the telephoto focal range and frame up a close-up shot of your subject that has plenty of space between them and the background. You may need lots of room behind your subject. Set the aperture as low as possible while maintaining proper exposure and shoot an 8 second clip. You probably will not get a very narrow depth of field.

Shutter ________ |  Aperture ________ |  ISO ________  | Focus  | Movie Size: 1080 x 720 60fps

Station 4: 55-250 Zoom Lens
Zoom all the way out to the telephoto focal range and frame up a close-up shot of your subject that has plenty of space between them and the background. You may need lots of room in front of your subject. Set the aperture as low as possible while maintaining proper exposure and shoot an 8 second clip. You should have a very narrow depth of field.

Shutter ________ |  Aperture ________ |  ISO ________  | Focus  | Movie Size: 1920 x 1080 30fps
