forget about floodlights
you need about 650w - 1000w with a fresnel to get a decent exposure...this is before you filter the light to get it balanced for daylight
get strobe lights instead (you can try first with a jinbei)
strobe lights are not dependent on the shutter speed because they fire off a lot of light in a fraction of a second (faster than the sync speeds on most cameras)
may i know roughly how much is jinbei?
after doing more research i found out it's better to use multiple flash. can someone recommend the cheapest way to do it? and how to trigger it. i currently have one 430ex. so i need another two right?
