STOP Asking About Flash Power | Ask These Questions Instead

I see it on facebook. I see it on instagram. I get it in the comments of my videos here. "What was the power of your flash?" Aside from the obvious fact that it's silly to expect any photographer to remember their specific flash output from a single photo. I mean, they are busy managing lighting positions, making visual decisions, communicating with a subject, etc. And I don't know a single photographer who keeps field notes of their flash power in a digital era where people can rattle off hundreds of photos per hour.
But even if they did happen to know, the answer does no good to the person asking. In this video I lay out all the reasons why chasing the flash output will not help anyone replicate the style of an image.
But, to avoid only creating a video where I rant through the list of reasons why this is a bad question, I also provide some questions that are better to ask, and will yield answers that can improve your photogrpahy.
