1. There will be more light hitting the sensor on a 40mm @ f/4 then on a 20mm at the same f-stop
Select one:
True
False
• The correct answer is 'False'.
2. Note: The statement is incorrect because even though both focal lengths generate different aperture sizes, on the 40mm one the light has to travel twice as further in order to reach the camera sensor
3. 10 - 12 - 16 - 20 - 25...etc
Going from 12 to 20 ASA means an increase of 2/3 of a stop
Select one:
True
False

Note: Every change of digits increase 1/3 of a stop
4. Lighting one side of the face at f/11 and 160 fc and the other at f/2.8 represents a ratio of 8:1, and consequently, 10 fc for the Fill side
Select one:
True
False

Note: the ratio should be 16:1 instead
5. The best way to read the light level off a floor lamp shade is to set the meter in incident mode and read it from camera position.
Select one:
True
False

Note: Should be set to reflective or spot mode and be read from camera position
6. There are no specific foot-candle increments, but if one starts the scale at 1.2 then the sequence must look like the following:
1.2 - 2.4 - 4.8 - 9.6 - 19.2 - 38.4 - 76.8 - etc...
Select one:
True
False

Note: The statement is right. For every doubling of the numerical number means 1 stop of light.
7. The lighting ratio of a subject lit with the Key at 2.8 and the Fill at 1.4 is the same if the levels change to 1.4 (Key) and .7 (Fill)
Select one:
True
False

Note: It doesn't matter the F-Stop levels as long as their difference is the same, here for instance, 2 stops.
8. The foot-candle increments behave in linear fashion because going from 60 to 3.75 fc means 5 stops difference.
Select one:
True
False

Note: 4 stops only 60 - 30 - 15 - 7.5 - 3.75
9. The DP is shooting a car commercial where the car is pure black and reads f/5.6 in his/her reflective meter. Shooting at this f-stop the car will be 2 stops underexposed.
Select one:
True
False

Note: It should be 2 stops overexposed instead. The result will be a brighter black because of the meter's assuming it's darker than really is
10. The F-stop measurements change in exponential fashion, so going from f/5.6 to f/11 results 4 X the amount of light and not 2 X as much.
Select one:
True
False

Note: That's right. Going from f/5.6 to f/8 one doubles the amount of light and from f/8 to f/11 one doubles again (2 stops).
11. Lighting one side of the face at f/5.6 and 40 fc and the other at f/2 represents a ratio of 8:1, and consequently, 5 fc for the Fill side
Select one:
True
False
• The correct answer is 'True'.
• Note: 3 stops difference from 40 fc takes to 5 fc for the Fill (40 - 20 - 10 - 5)
