What is a PinShot Camera
1) It is a Pinhole Camera.
2) It is made out of plywood. The camera was designed in CAD. High grade premium plywood is then cut with laser. The pieces are assembled by hand with great care and attention to detail.
3) It has a curved film plane. This is very important because the light has the same intensity at the center of the frame as at the edges. So you get even exposure across the whole frame and a slightly wider field of view.
4) Uses readily available 120 medium format films. Film advance is done with the knobs on top, and you need to look through the small window on the back to know on what frame you are.
5) Has interchangeable apertures: (1) pinhole, and (2) a zone plate (work in progress)
6) It has FULLY AUTOMATIC EXPOSURE

What does the Fully Automatic Exposure do – how does it work?
1) The camera has an electronic circuit that was designed from scratch for the sole purpose of calculating exposure and controlling a shutter mechanism.
2) There are 3 components to the AE system: (1) The Brain with a display and controller (joystick); (2) Light Sensor; (3) Shutter Mechanism.
3) The Brain contains the database of current films with their respective reciprocity failure curves; the essential dimensions of the pinhole diameter and focal length, and the mathematical algorithms to calculate exposure. Through the Joystick you can select the film, and change EV (and other functions). Once you select the ‘Shoot’ function it opens up the shutter curtain and starts to make light measurements at one second intervals. Each reading gets integrated with the previous readings and sums all of them until proper exposure is achieved. The system will increase or decrease exposure based on light condition changes.
4) The system is runs on a lithium battery, rechargeable through a mini USB port. The system was designed to consume very little power during exposures – even if they take a few hours, so one charge will last for a long time.
