Flash Power and Aperture Are the Same Dial: Here's How to Read Them Together

Flash Power and Aperture Are the Same Dial: Here's How to Read Them Together

Early in my career, I treated flash power and aperture as two separate problems. I’d fire a test shot, decide it was too bright, randomly close down my aperture, fire again, still wrong, then start fiddling with the flash power. No logic to it. Just guessing with expensive equipment. It wasn’t until I really internalized the stop-based relationship between those two controls that my exposure work became something I could actually reason through instead of stumble toward.
