Hi Everyone! In my garage based studio, I shoot with 5 AB400's, all in softboxes or grids. I can not seem to turn them down low enough to get a wide aperture for shallow DOF. I typically have to shoot around F5.6 plus or minus a half stop. What I thought about doing is to order a 2 stop ND filter, and shoot thru that. I use the D200 and the 28-70 F2.8, so I should be able to get some very shallow DOF, right? What do you think about that plan?
