I'm new at this and have no clue on flash / studio lighting. My question is ... with 1400 watt seconds how much light should I be getting from my flash meter reading? Is that (1400 ws) relativlely low? That would be 700 each. I'm using two units w/bounce umbrellas at about 5 ft from my subject. My readings are very consistent at about 1/8th second at about f/2.8. Walls are dark paneling, carpet is dark blue, subject is dark brown, film speed is 100. This is just a test - nothing major. It just seems as though I'm not getting much of a reading. I expected more from studio lights. Camera to subject was 6 ft. Is this normal for this power supply? Its a brownline.
