Doug, Sorry about taking so long to respond to your e-mail, but I've been on an extended business trip & just got back home. I also use a flat, small, light box as a soft light source. I have two of them and they are great. Another idea for soft or indirect lighting is to build a square frame out of 1" PVC pipe and drape a white sheet over it and then aim the light through it. Almost shadowless lighting and very wrap-around. I've also used an SC17, Nikon off camera cord to connect a Metz 32CT4 flash with an SCA351 module to an R5, or R6.2 body and then connect another Metz to this with a Nikon SC10, male-to-male cord and connect that to a Nikon SC10 Shoe and you have a multi-flash TTL set-up that you can shoot through the light tent with. With this set-up, you don't have to worry about flash calculations, just enjot the results. The same set-up should work on an R8~9, or even an M6TTL, using an SCA3501~3502 Metz flash, because the pin positions are still the same! Just a thought Art Tafil
