so i'm shooting about 25 individual commercial portraits tomorrow and i really would like to set up one of my speedlights for rim lighting and the other for fill on their face. i would be setting up in a long hall way so i have plenty of room and the ceilings are 10-12 feet high. does anyone have a link to a site that would help me fine tune some of the details for creating this sort of light? thanks so much!
