  1. A lens set at f/4 admits how much more/less light than one set at f/2.8?Reflected light meter

          

  2. 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?No change. The EXPOSURE doesn't change or it would also change the background as well. Move the lights to adjust.

          

  3. What are quad- and hex- tone printing?Inkjet black & white printing where color cartridges are replaced with shades of gray, resulting in smooth tones and slight color cast

          

  4. How can you change the brightness of the background when using flash?Change the shutter speed. The longer the shutter speed, the lighter the background will be. The faster the shutter speed, the darker the background will be because less existing light is captured.

          

  5. An 8x10 at 240 ppi will have a resolution of what?1920 pixels by 2400 pixels (4.6 million pixels)
