Maybe I should title this "Flash Fixation" or how to use as
many flashes as possible in a small space :)
OK, the details :
The brown glass jar was placed on a sheet of glass from a cheap picture frame which had the underside spray painted black. Behind a large (A2) sheet of red card to refect onto the glass.
To the sides a pair of fixed output Neewer SF-01 mini slave flashes shot through white printer paper screens.
Obscured behind the left screen is a third Neewer SF-01 lighting the bottom of the red background, while mounted above is a Yongnuo YN460 set at 1/8th power which is the main background light.
All flashes fired by Blazzeo SLT-4 radio triggers for convenience, as I was swapping lights around during shooting, so it was easier than using the optical sensors.
