I will be using two 5' bounce umbrellas w/ B800 AB's for a large family portrait. (17 family members...) I need to know how to position the umbrellas. Do I get them as high as I can, aimed up, down, perpendicular, angled in, straight on, etc? The portrait will be done in a home with 8' ceilings. What kind of fan do you use for a hair fan? How do you blow air from the front w/o making the model squint??? I've been asked to do a portfolio for a co-worker's daughter. She is applying to a modeling school and they require a portfolio. Can you give me a minimum pose list that would constitute a decent portfolio? TIA!
