My portable photographic studio

For my shots, I recently made a portable folding studio. If the weather is good, I can use it outside in the daylight, and for rainy days, I bought two "daylight" type lamps for indoor use.
My nephew rémi, designer and illustrator, uses for his creations plates of insulating foam (Depron). I had the idea to use a plate of this kind, mounted on a plywood frame.

Once the depron plate removed (and behind a piece of furniture) here is what my studio looks like: three plywood boards assembled by piano hinges and wood strips used to hold the plate.

Folding: first the sloping support(you can see on it's back the strip used to lock against the vertical part) then the vertical board.

And now, I just have to put it behind another piece of furniture!

The whole in running order; I did not ((yet) find background paper with the right dimensions, then I use Kraft paper. I layed down on it a translucent plastic sheet, it protects the paper and keeps it flat. The lamps (low consumption "daylight") come from Pearl Diffusion.

I found rolls of colored kraft paper to use as background...

Lighting

I bought tripods with umbrellas.

Each head is intended for two daylight lamps, that's what I used (above) to illuminate my lenses tests. For the studio, I replaced them with low-energy bulbs and slave flash units.

The bulb is used as pilot-lamp, the exposure is made by the flash (controlled by a small socket flash masked by an infrared filter on the camera). Guide number 22 for subjects of the size of a camera, diaphragm 11 or 16 for iso 100.

I also bought two single lamp tripods, fitted with parabolic reflectors. Rather for the portrait.

And my lamps of the beginning are now used for the copy stand.
