Hi Mark,

Thanks for this, the DIY softbox sounds great. The only thing is that I’m having trouble visualising how the air gap works. To try and clarify a bit:

– You’re saying that the dimensions of the rear end of the soft box should be the same size as the square frame where the barndoors are hinged onto the light?

– When you attach the softbox to the barndoors, what should be the distance between the back of the softbox and the light head?

– When you clip on the box, should the barndoors be on the inside of the cone, or on the outside? Or does it matter?

Thanks a lot for your help.
