I am photographing a conference next week and want to improve or kick up my lighting. Usually I would hit the presenters at a smallish panel session with on camera flash either bounced or using a Demb flash card. I am now thinking I want to quickly put a remote (nice new 600EX-RT) on a high stand, then move to the center or other side of the room and use some on-camera fill. Time will be crucial and I don’t want to fiddle with a modifier on the pole light, but I am worried it will be too harsh. I have a HONL traveller16 Softbox, but it is a pain to put on quickly. Thoughts?
