Basic Daylight Exposure
· The Sunny 16 Rule
When it’s sunny, set the f-stop to 16 then the ISO and shutter speed are equal. · The BDE wheel The BDE wheel helps us to create exposure based on the sunny 16. Steps to use the wheel:

Depth of Field
· Three Ways to affect DOF
Change the f-stop,the aperture, and camera subject distance. · F-stop to create shallowest DOF The lowest number f-stop will create the shallowest depth of field. · Why is the largest f-stop number the smallest opening? Because f means fraction, small fractions have large numbers. |
Shutter Speeds
· How to create panning
To create panning, you follow the subject, the subject is moving, and set the shutter speed to somewhere between a 30th of a second to a 15th of a second. · Shutter Speeds that creat frozen action At 1600th of a second to a 400th of a second · Why does the same shutter speed not always express motion in the same way? It depends on what the movement is, because the speed of the subject determines your shutter speed. |
ISO
· What is ISO
Sensitivity to light · Trade-offs for ISO The noise is increased, but lets us use faster shutter speed. · If you wanted to shoot with shallow depth of field in full sun, what would be the best ISO? 100 · If you wanted to shoot with a fast shutter speed inside, what would be the best ISO? A high ISO I.e. 1600 |
Built-in Light Meter
Using a light Meter
· Three controls to determine correct exposure ISO, Shutter Speed, and aperture · Meter will always average to: Middle gray · How can you overcome a misleading light reading? Zoom in on their face, take the reading there and then zoom back out. · How many stops +or- should you adjust for a white on white scene like the snow? Plus 2 stops |
