I’m sure I should already know the answer to this, but currently I can’t think what it is.
I’m trying to measure the flash output of flash units combined with different shutter speeds with a leaf shutter, so using a meter is not an option as the vagaries of the shutter system will affect the exposure too.
So I want to measure the level of over and underexposure on the RAW test image on the computer, Is there a way to do that using Photoshop or similar software? Do the exposure slider numbers in Lightroom equate to stops? Any ideas folks please?
