- An incident-exposure reading for a fair-skinned subject reads f/8, 1/125th at 100 ISO. The next subject is very dark skinned. What is the proper exposure for the second subject?
- An image made of pixels is sometimes called what?
- When the subtractive primaries are added together equally, what is created?
- lossless compression
- a No change. The EXPOSURE doesn't change or it would also change the background as well. Move the lights to adjust.
- b Toggle stack
- c Black. Subtractive primaries are Magenta, Yellow, Cyan
- d A raster image
- e An image-compression scheme, such as TIFF, that preserves all image detail. When the image is decompressed, it is identical to the original version.

5 True/False questions
Draw perfect circle/square → A point of focus where everything from half that distance to infinity appears to be acceptably sharp. For example, if your lens has a hyperfocal distance of four feet, everything from two feet to infinity would be sharp. The hyperfocal distance varies by the lens and the aperture in use. If you know you'll be making a grab shot without warning, sometimes it is useful to turn off your camera's automatic focus, and set the lens to infinity, or, better yet, the hyperfocal distance. Then, you can snap off a quick picture without having to wait for the lag that occurs with most digital cameras as their autofocus locks in.
high-speed sync → A method for syncing external flashes at shutter speeds higher than their maximum sync speed by increasing the flash duration through multiple bursts to match the speed of the focal plane shutter.
fringing → In an image, pixels with randomly distributed color values. Noise in digital photographs tends to be the product of low-light conditions and long exposures, particularly when you've set your camera to a higher ISO rating than normal.
polarizing filter → A lens attachment with variable density or color from one edge to another. A graduated neutral-density filter, for example, can be oriented so the neutral-density portion is concentrated at the top of the lens's view with the less dense or clear portion at the bottom, thus reducing the amount of light from a very bright sky while not interfering with the exposure of the landscape in the foreground. Graduated filters can also be split into several color sections to provide a color gradient between portions of the image.
What is burning? → Selectively increasing print exposure, which will make select parts of the image darker
