Hi Shane....yep...those in the photo are for holding a lastolite ( A TRADITIONAL ROUND ONE) and if I recall, dont they fit into the tripod stands instead of the lights ?.......I bought them years ago and never used them as I prefered Mrs W to hold them for me !!!..but I do think the fitting is the same as the ones for the lights.....the wee dongle for the lights drops out of the bottom of the light bracket...and its fits into the arm that you have in the photo above.........if you were using just one light then the other tripod etc would hold the lastolite....but like I say I got Viv to hold them for me....or anyone else who was around TBH..
the diffuser material is exactly that......and again it came with the kit but I never used it TBH....I guess it would go over the front of a softbox ????
hope this helps.
hope the traffic wasnt too bad on your way home ?
nice to meet up, even tho we probably did look a bit dodgy doing deals at the side of the public way !! LoL
