1.Set the Shutter Speed Dial to the synchronizing speed of 1/125 sec.

2.The guide number is indicated on the flash unit. Use the guide number in the following equation to obtain the f-stop number and set that number to the f-stop index line.

For example. with a flash unit with guide number 40 for ASA 25, and camera-to-subject distance of 5 feet:

f-stop number (8) = Guide number (40)

--------------------------

Camera-to-subject distance 5 feet

With automatic flash units, set the f-stop number designated for automatic flash photography.

*It is convenient to use the quick reference table on the flash unit, which shows the f-stop numbers already calculated.
