slit scan reel 1987 

I agree, I want to try to simulate slit-scan using something like avisynth but I'm not really that good of a programmer. But I suspect the rotation can be accomplished by rotating the slit a few degrees for each frame?

Slit scan was a technique of filming moving, back lit art work synchronized with a moving, computer controlled camera, using a long exposure on 35mm film. For example a thin slit would travel over a transparency while the camera pulls back. The artwork would also move progressively on each frame and the result was like the star gate effect in 2001. Another effect was giving a title or a shape perspective depth or tail. This could be lengthened or manipulated by timing and camera movement on each frame exposure. A good example are the Superman title sequences. My favorite technique was to use two artworks moving across each other which twinkle and create particles streams, which can be moved and animated by the camera movements and timings. All slit scan, even though programmed and automatic, took at least a minute per frame to film. So a five second sequence could take two hours to film. Most sequences required several layer which could be shot on the same piece of film or shot separately to be composited later. I still operate computer controlled cameras or “motion control”. As you can tell, I have a bit of time on today’s commercial to reminisce a little.

It's funny you should mention the Superman title sequences, as watching that last night for the first time in a while prompted me to find your video :) I also love the wormhole shot in Star Trek: The Motion Picture, but not sure if that's also slit-scan.. I think I can visualise how the slit-scan works in the 2001 stargate sequence (or your flying over the city at night shot..), but what kind of process did you use for sequences like the rotation at around 0:25? Is the volcano wide shot a volcano silhouette shot first, then the same film used for the lava flows (although they follow the perceived land contours really well :S).. then a third pass for the lava plume? Some shots like the close up lava.. rotating ring.. or rippling water.. just look really 3D and beautiful and it's difficult to understand how they could be made to look so convincingly like 3D objects.. how much precalculation/programming did you have to do on the Oxberry in advance.. and did you have to tweak the background art a lot to make things look right? Was there any way aside from visualising it in your mind to figure out what the effect may look like beforehand, or did you just have to use up film testing it out and refining every time? Anyway the trips down the pub while the process ran its course don't sound too bad :)

@@Wagoo Wormhole was a laser scanner + long exposure, but similar concept.

Reading this in my Soho Basement, pushing particles instead, we're definitely missing a trick ;O)

These are astounding, even today! Can you tell us how you did each of the effects? This stuff is so good and I would love to incorporate similar effects into my work one day and make new ones.

These are stunningly creative. Was the camera shooting 16mm or 35mm?

but i saw trt haberler

Yes, off course. Feel free.

That’s like saying Leonardo’s paintbrush did all the work on the Mona Lisa, not him
