Pulso and Primo Questions

1. What is the guide aperture (GA) of both the Pulso and Prim units?

64

2. Lets assume you had a flash unit with a GA of f64. With the subject placed 4m from the flash head the f-number to use to achieve correct exposure would be

f32

3. Using the same flash unit as in question 2 above and a subject placed 16m from the flash head the f-number to use to achieve correct exposure would be

f8

4. Changing the pulso 2 power setting from 10 to 9;

halves the output

reduces the output by 50%

reduces the output by '1 stop'

would require the use of a lens aperture 1 stop wider to achieve the same exposure

5. Describe what you understand by the term Symmetrical Power Distribution

Using more that one flash head, the power percentage is distributed evenly.

eg 3 flash heads - 33% power to each flash head
