- A filter with a factor of 2 requires how many stops of compensation?

- An in-camera reflected meter reading a very dark scene indicates an exposure of 1/250th at f/8. For a correct exposure, what should you do?
- A tall vertical line on the right hand edge of a histogram indicates what?
- What is gamut?
- a factor of 2 = 1 stop compensation. (Each time a factor doubles, it's one additional stop)
