Pi Cam Replaces Pinhole and Film For Digital Solargraphy #piday #raspberrypi @Raspberry_Pi
Make some unique photos with this method posted on Hackaday.io. I had never heard of solargraphy but am now intrigued. The process involves recording the movement of the sun with a pinhole camera and extremely long exposures. Via Hackaday:
To automate the process, [volzo] used a Raspberry Pi and a Pi-Cam fitted in a weatherproof 3D-printed box. A custom hat powers up the Pi every few minutes, which boots up and takes the two pictures. Sadly, the batteries only last for a couple of days, so those long six-month exposures aren’t possible yet. But [volzo] has made all the sources available, so feel free to build on his work. If you prefer to use a DSLR for the job, this Bluetooth intervalometer might help.
