CALCULATING EXPOSURE - MANUAL FLASH
In the manual mode, you must calculate exposure based on the distance the flash head is from the subject (flash to subject distance). Here are three common methods of determining exposure using flash:
1. Use the chart or calculating dial on the flash body. Set the ISO to the speed you are using, measure the distance and adjust the aperture to the indicated setting...OR...
2. Use the guide number provided by the manufacturer in the instruction manual. To determine exposure:
f/stop (aperture) = Guide number at ISO
flash to subject distance
3. Use a flash meter to measure flash light.
