DoubleHalf

A double exposure half-frame film camera emulator for iPhone.

Half-frame cameras split one frame of 35 mm film into two tall pictures side by side. Double exposure takes the same roll of film and runs it through the camera twice.

DoubleHalf does both of these: four captures composited into a single frame.

Fixed everything

There is no autofocus, no HDR, no computational processing. Focus and white balance are pinned. You point it and you press it, and you find out later what you got.

With the flash on, exposure is pinned dark and the lamp carries the picture, so a subject falls off hard into black. Turn the flash off and the camera meters the room instead.

Single exposure

You can also turn the double exposure off if you want, making it a single-exposure half-frame camera emulator. Two presses of the shutter instead of four.
