STEENBECK ST16 TELECINE MOD

[Robert Hart]

Does anyone have a circuit for dummies which will power and receive signal from an optical interrupter, triggered by a slotted disk. It is to set off a LED flash and trigger a camera ( SI2K ) in single-frame mode.

Robert, if you get a succinct answer to this question in the next 48hrs, then Reduser is officially the best forum on the planet.

Good luck with your set up, its sounds like a great idea!

It will be a contest between reduser and dvinfo as to which comes up with a solution. The Steenbeck has been done before but the detail of the secret sauce was not available. Likewise there was a scanning solution for the SI2K but the original engineer has apparently passed on and his secrets along with him.

Ultimately the SI2K may not be suitable for flash scan with single-frame triggering except at very slow film speeds because of rolling shutter artifacts. Hever once I get the optics sorted which is fairly close now, I will roll the Steenbeck and the camera with a 1/500 shutter to see if the notion works in any way at all. A jigged up arrangement with the optical block removed from the Steenbeck and a substitute lens yields an image which seems limited only by the resolving power of the test film which is a one light contact workprint.

Steenbeck themselves have reinvented their flatbeds with their robust, gentle and steady film transports into film scanning systems fully integrated with inbuilt firmware and software but for humble peons like me, they are also very expensive.
