Getting the Correct Exposure

1. What is a gray card used for? What does it help represent?
2. What is a waveform monitor used for? How should you use it?
3. What is false color? How can it be used to determine exposure?

The grey card is used to get correct exposure on skin tones. the correct grey card can help represent the necessary settings for the skin tone to be exposed correctly. A waveform monitor can be used to identify the exposure levels at the image. The grey card in front of the monitor will appear as one thick card, therefore adjusting the thick line to the correct position can signify the best  possible exposure. Typically, having the grey card exposure set to 40 would create the ideal exposure. False color is also identifies the exposure levels of an image. This can be useful when the camera operator needs to isolate the specific subject that has extreme exposure levels.
