When shooting two people on a bed using 500 watt lights
 

What size softboxes would you use? Mine are getting long in the tooth,thinking of going bigger.They are the original ones that came with the light kit, 24x24. Your thoughts?

hit the ceiling and one wall, that makes a pretty big box

I have two tota's already bounced off the ceiling, these two soft boxes are facing the models.

just get a 4x4 or 6x6 frame and then use a silk. try it out with pvc pipe just for kicks sometime.
