An analog pinhole camera for two

One photo. Two people. Not on the same day.

You expose one half, someone else the other, weeks or years later. Together they become one picture neither of you could have made alone.

A finished Both In Time picture: coffee-developed, toned blue-indigo.

Yours is the beginning. The ending belongs to someone else.

The Both In Time pinhole camera from the front: kraft cardboard, red square, band with the taped needle, two sealed holes.

Built by hand in Stuttgart. Inside, the photo paper lies in the dark.

You pierce the left hole. Pull the needle out and your exposure begins.

No lens, no electronics. Light falls through a tiny 0.3 mm hole. A small, upside-down image forms on the back wall. Straight onto the light-sensitive photo paper, like in a darkroom.

The camera is passed on. To another person, to another place, on another day.

Days, weeks or years later, that other person pierces the second hole.

Their image forms on the right. Yours lies on the left, in the dark the whole time.

The drawn negative turns 180 degrees and becomes the real coffee-developed negative.The finished positive: a coffee-developed pinhole picture, toned blue-indigo.A finished Both In Time picture: coffee-developed, toned blue-indigo.

Both exposures on one picture. Upside down.

Five minutes in the darkened kitchen, under red light: instant coffee, vitamin C, baking soda. The image slowly appears in the developer.

Now you both see for the first time what you made together. The negative is reversed. Only now is the picture finished.

Together, not at the same time

Two halves that never met.

You expose one half of the paper, then let the camera out of your hands. Someone you love, or someone you'll never meet, exposes the second half.

The picture only becomes visible in the coffee: five minutes in a darkened kitchen, under red light. Then both halves are there on the same sheet of photo paper.

The finished positive: a coffee-developed pinhole picture, toned blue-indigo.

One camera, two hands, coffee.

  • Pure optics

    A 0.3 mm hole. No glass, no lens, no electronics. The light draws straight onto photo paper.

  • Handmade

    Small batch from Stuttgart. Every camera is built, checked and packed by hand, and every one carries its own stamped number.

  • Caffenol

    Instant coffee, vitamin C, baking soda: under €5 together. No chemicals to order, nothing toxic down the drain.

Workshop in Stuttgart.

Five hours, six seats, one negative. We expose in pairs and develop together in Caffenol.

Common questions.

  • What is a pinhole camera?

    A camera without a lens.

  • How long is an exposure?

    From four seconds, depending on the light.

  • What is Caffenol?

    A developer made from instant coffee, vitamin C, and baking soda: ingredients from the supermarket and drugstore, under €5 together.

  • What does the finished picture look like?

    Black-and-white, but not neutral grey: the negative comes out of the Caffenol in a warm sepia tone, soft and painterly, like the example pictures on this page.

  • Does the room really have to be completely dark for developing?

    Yes, completely dark.
