I have figured out how manual flash calculations work. For example my FlashQ has GN 20 at ISO 100 with 1 meter distance and 1/8 power I should use f8. OK.
But how ambient / existing light is calculated / accounted? I mean if I have ambient light congitions EV(100) = 8. How is this calculated so that the flash lit target is exposed correctly?
This might be really basic and stupid question but I cannot find any answer to this by google, all I find is DSLR TTL automatic yadayada..
