The studio is a portable three sided foldable light box. It is here illuminated by two flashes. The first is mounted "on" camera, but off the usual hot shoe shoulder by means of a bracket attached to the camera tripod mount. This puts the flash further out and higher with respect to the lens than the standard hot shoe, which on this camera -- the Sony R1 -- is offset to one side on top of the battery holder.

The flash bracket also allows the flash to be tilted and swivelled to aim directly at the close subject, in this case the row of close up lenses. A rear view of the bracket to show its details more clearly can be found here.

The second flash is mounted on a tripod to the side of the box, at a height where the bottom half of its light will hit the near screen, and be diffused through that onto the subject. The top half of its light will pass over the top of the near screen, and some of that will hit the far side of the light box and be reflected back as a diffuse reflected fill in from that side. Finally the top of the beam will hit the angled reflector and become a diffuse top light over the subject.

In addition to this the off-the-shoulder camera flash was set to a low manual flash to provide a small amount of direct forward lighting to make the writing on the sides of the lenses visible.

The side flash is mounted on a Cactus radio trigger, but that's switched off because my camera won't drive both the hot shoe and the flash trigger cable simultaneously, so the side flash is optically triggered by the off-the-shoulder flash. The optical trigger is rubber banded to the top of the flash, and connected to it via an interpolated hot shoe, because this flash hasn't got a cable connection.

I wanted f16 for maximum depth of field, so I tested out the big side flash at half power with an incident light flash meter, and discovered that for f16 it needed to be on full power.

I took a sequence of three photographs with this set up. The first used full power off-the-shoulder flash only. The second used low power off-the-shoulder with the side flash, but without the overhead reflector. The third added the overhead reflector.

Flash guns triggered by Cactus V2s's.
