Things are starting to look up. I’ve arranged a few activities, including a trip to Edinburgh, and the theatre visit and painting course I booked a while ago are both imminent. I’ve also started thinking once more about my slitscan sketch in Processing.
I watched a brief explanation on DVD of how Doug Turnbull created the slitscan sequences in ’2001 A Space Oddessey’. It turns out that he achieved the mottled effect not by filming the slit itself but by filming its reflection on a roughly textured mirrored cylinder. I realise that this is being pedantic, but since random noise was introduced into the sequence, it’s impossible for anyone, despite their claims, to decode the original images used in the slitscan sequences. These re-creations still have the noise in them.
It would be possible to introduce an equivalent noise to my Processing slitscan sketch, but I’m still keen to try my hand at an analogue version. That will have unavoidably irregular movement of the camera on the vertical axis anyway, which may be sufficient distortion.
