Using Camera Modes
Camera modes on DSLRs are relatively similar in function. Refer to your manual for what your different camera modes control.
Remember: The more you can control in the camera, the less you have to do in Photoshop!
Advanced Auto; No manual control.
Tv: Time Value or Shutter Priority (Sp or S)
Allows photographer to set the shutter; camera sets the aperture.
Av: Aperture Value or Priority (Ap or A)
Allows photographer to set the aperture; camera sets the shutter speed.
Allows photographer full control over aperture, shutter speed, and ISO.
Shutter stays open for the duration that your finger is pressed on the shutter. Useful for exercises such as painting with light.
Auto: Full Automatic
No manual control
CA: Creative Control
Camera sets aperture, shutter, and ISO; Photographer sets brightness, depth of field, color tone.
A-DEP: Automatic Depth of Field
For subjects in foreground and background to be automatically in focus; sets automatic aperture for the scene.
1. Set your ISO to 400
2. Set your camera to shoot RAW format
3. Set your white balance to AWB (Auto White Balance)
4. Set your camera's color space to Adobe RGB 1998
Aperture: A hole in the camera's lens and increases or decreases in size to allow a certain amount of light to enter the camera and strike the sensor. Measured by f-stop.
Adjusting Your Aperture
1. Get a feeling for changing your Aperture. Set your camera to Ap or A (Aperture Priority). To change your Aperture, simply rotate the wheel or press the button.
Work in groups of three. Photograph your two partners at least 5 feet apart at the same focal length. Don't zoom in or out between images.
1. Take a photo with your camera's lens set to the widest aperture (f4, 5.6).
2. Take a photo with your camera's lens set to the smallest aperture (f22, 32, or 64).
Shutter Speed Exercise
Shutter Speed: The amount of time a camera's shutter opens and closes and allows light to enter the camera and strike the sensor. Measure in fractions of a second (ex: 1/125)
Adjusting Your Shutter Speed
1. Get a feeling for your camera's shutter speed dial. This is usually a button or a rotating wheel. Once you have located this button/wheel, watch the shutter speed change.
2. To adjust the shutter speed alone (and let the camera set the aperture) set your camera mode to SP or Tv.
Have a friend run parallel in front of the camera (across the frame and not towards you).1. Take one picture with your shutter set to 1/8. (May be represented as 8 on your camera).
2. Take one picture with your shutter set to 1/30.
3. Take one picture with your shutter set to 1/500.
