I want to use two flashes with umbrellas. I know I could use a lot of duct tape and stuff and stick it all to a cheap tripod, but id like to get light stands and do it the “real way” After looking at light stands, umbrellas, things that’s hold an umbrella on the stand and things that hold the flash on the stand, I’m totaly confused. The flashes are both going to be on Nikon TTL cables with hotshoes, so I need something that has a screw the same thread as a tripod to hold the flashes and holds an umbrella and mounts on a lightstand. are the tops of lightstands threded or are they just like a pin? what do i need?
