Understanding power ratios

At this point in the course, we've discussed how the scales are calculated. We know what a guide number is and how the math allows us to create equivalent flash exposures by making offsetting moves with our ISO, our flash to subject distance, and our aperture. We've seen examples of how it works in a controlled setting. We'll also see how to apply this information during a live model shoot. Troubleshooting lighting problem shouldn't be a trial and error, hair-pulling, time-wasting, iterative process of elimination. Now, we're going to end our primer on small strobes by introducing power ratios.

Power ratios are manual settings on the flash that allow you to reduce the guide number by shooting at less than full power. They provide another level of control that you can use to make your manual flash more versatile. Well, small strobes and strobe packs give you the option of shooting at full power or the variety of lower outputs. In the case of most small strobes, you can adjust the...
