Workshop 2 – Studio Research Task 1
1. Describe the difference between Flash Guide Number and Flash Guide Aperture.

2. What is the colour temperature (CT) of an electronic flash discharge?

5,500 - 6,000 K

3. In the given situation below there is a subject that is lit by a light source from the left side and a
reflector on the right side. A light meter can be used to determine the level of illumination on each
side of the subject. That being the case if the meter indicated f8 on the lit side and f5.6 on the shaded
side the lighting ratio would be;
[a] 1:0
[b] 2:1
[c] 4:1
[d} 8:1

 It would be [b] 2:1


4. If the readings were f8 and f1.4 respectively what would the new lighting ratio be?


I would be 32:1 (5 stops)
