So flash photography is generally measured by fractions of a flash's full power, ie., 1/2, 1/4, 1/8 power.
But what confuses me is that if you take different flashes, and set them all at full power, each flash is going to output a different amount of light, no?
Which leads me to think that there's no way of knowing how much light a flash will output if you just bought it. Is there a universal measure for flashes? So that you can, say, compare 3 different flashes outputting at 1/1 full power, yet still know how much output you're getting from each.
Thanks,
let me know if that was unclear.
