2A) If you DO NOT have a flash meter, then you take test shots to determine the proper settings. I always start with my strobe power set at ½ power. That is 3 on the Gemini and -2f on the White Lightning. With camera set up I take a picture with the fstop set to f11. If the picture is too bright, (check your histogram), then I lower power on the strobe rather than change f-stops’. I like f11!The content you are trying to access is only available to members.
