I think you made sense. Identical power output, and same distance from subject for each flash means you can control "fill" from one of the flashes with ND. As a matter of fact, the Old Timers will tell you that you can experiment with layers of tissue paper rather than ND filters to do the fill. The general rule of thumb is, I think, that two layers of Kleenex tissue is about 1 stop lost. -Lon, who rarely uses one flash and has Never Used Two. - This message is from the Pentax-Discuss Mail List.
