Camera
Shutter Speed
Exposure time - length of time when shutter is open and exposed to light.
- 1/4000 will freeze fast movement
- 1/250 portraits, will freeze walking people
- 1/150 general wildlife
- 1/125 general landscapes
Aperature
Opening in camera lens that is able to limit the amount of light passing through the lens and hitting the camera sensor.
- f-stop = aperature size; small f-stop = large aperature
- f/1.4 very large, bright, small depth of field, nothing in focus
- f/22 very small, dark, large depth of field, everything in focus
- For blurry background, use low f-stop
ISO Speed
How quickly the camera reacts to light and records an image.
- Low speed works great with lots of light
- High speed works better when dull or dark
- Higher the ISO, the noisier the photos. Generally keep low ISO (100-400)
Recipes
Portraits
- Shutter Speed 1/250 to freeze walking people
- Aperature 2.8 to blur background
- ISO 100-400 to reduce noise for bright scenes
- Focus mode - autofocus single point
- Drive mode - single shot
Other info
- Shutter Speed at least 1/200th handheld or 1/15th on tripod (faster when photographing kids)
- Aperature f/2 to f/4 for single subject, f/5.6 to f/8 for groups
- ISO 800 if dark scene
Backlit Subjects
- Shutter Speed: 1/100 to 1/640
- Aperature: f/2.8 to f/5.6
- ISO: 100-200 (lower bc of strong light)
Other info
- Combine wider apertures (from F/1.8 to F/5.6) with fast shutter speeds to get a significantly overexposed image (if you donโt want to create silhouettes) and a very sharp figure.
- Use the exposure dial for a better creational effect. By overexposing a little (2/3 of a stop to start), it will darken the subject, giving your subject more detail. By underexposing, a silhouette will be created, which works great in many cases.
- Use a hood to prevent annoying flares, depends on the sun's position
