What aperture should you use for portrait photography? A: It's better to use a wide aperture (f/2.8 to f/5.6) to create a shallow depth of field behind the subject. Some portrait lenses can go as wide as f/1.4 What shutter speed should you use if the focal length of the lens is 55mm? A: A shutter speed greater than 1/focal length is recommended. For 55mm, a speed of 1/60 s or more is ideal What shutter speed should you use if the focal length of the lens is 300mm? A: Greater than 1/300 s If you are using AV (aperture priority mode) How could you increase your shutter speed?  A: By using a wider aperture or setting a higher ISO. What happens if you increase your ISO? A: The photo becomes brighter but also more noisy. What angle will make your subject appear taller than they are? A: Shooting from a low angle will make a subject appear taller than they really are.

Writing with light: Creating with light: Orbs/Streaks: Painting with light: Face/Ghosted Images: Questions: 1. The lower the f-stop what happens? A: The lower the f-stop, the brighter the image, but it lowers the depth of field. 2. The higher the f-stop, what happens? A: The higher the f-stop, the darker the image, but the DOF is increased meaning distant and close objects are in focus. 3. The shorter the exposure, what happens? A: The shorter the exposure, the darker the image. Shorter exposures freeze motion making light painting difficult. 4. The longer the exposure what happens?  A: The longer the exposure, the brighter the image. Longer exposures do not freeze motion, making them ideal for light painting. 5. What worked well? A. For most purposes, a high f-stop (f/8 to f/13), a long exposure (>10s), and a high ISO ( 800 or 1600) worked well for most of these assignments. 6. What was you
