RE: Eclair Cameras: Digest for EclairACL@topica.com, issue 593

I believe this is what the original poster was referring to:


Sure it could probably be replicated by someone with good mechanical knowledge, but I own a super-8 workprinter and it is a very good quality machine. I think the 16mm unit would be well worth the money if you plan on doing quite a bit of home transfer.

Haven't tried that. We have an Eiki telecine, which is just an Eiki 16mm film projector that has had a video pickup installed in place of the projection lens. It's not so hot. It really doesn't have adequate image controls.

Hi Wade,
I´m sorry but i think i didn´t do the proper question.
What i want is to modify my projector to telecine like "workprinter" units.
As it seems you have a more technical knowledge than i so maybe you can help me
