Photography is a science and an art. Not only do photographers need to have a good grasp on optics and chemistry (if they’re shooting film), but also physics. You can’t do physics if you can’t measure something, and that’s where this calibrated light source from Tindie seller Film Camera Tester comes in. This tool is how you calibrate light meters, either hand held or built into cameras). If your light meter isn’t calibrated, you’ll get over or under exposure, possibly ruining your shot.
The idea behind this calibrated light source is to be part of a larger kit meant for testing camera shutter and exposure settings. The Film Camera Tester is an Arduino-based kit meant to perform a variety of time-based tests and calibrations of film cameras. This includes testing the timings of shutters, the delay between flash contact and the shutter opening, and taking a series of measurements and calculating the average stats of a film camera.
The calibrated light source can be used with this Film Camera Tester to calibrate light meters, and is adjustable within 4-16EV, with a calibration accuracy of 5%.
Like vinyl records and CRT displays, what’s old is new again, and that includes film cameras. Sometimes digital just won’t do, and there are an increasing number of photographers shooting only on film. If you’ve got a film camera, odds are it’s more than a few decades old, and that means calibration is key. This calibrated light source, along with the film camera tester, gives you the tools to make sure your camera is working in tip-top shape.
