Hello everyone, I just thought I'd put together a quick post detailing my ongoing experiments in tricolour projection, that I'm undertaking for my MA studies at Derby University. I'm a tinkerer at heart and fascinated by the way that things bolt together, so the opportunity to spend some time working with the building blocks of colour photography has proved too good to pass up. I'm currently working with reversal processed Ilford FP4 shot in a Mamiya RZ76 through Lee lighting gels (three exposures for each subject, one through each red, green and blue gel). Obtaining consistent results from the reversal processing has proved to be a major challenge, but I think I'm well on the way to getting it under control. The 6x6 film frames go straight into glass slide mounts, which are then projected by three beautiful Gnome Alphax projectors (sourcing matching examples has proved to be another challenge). Registration is orchestrated by home made levelling plates that sit under each projector, and reworked slide carriers that use magnets to align the slide within the projector. Finally, a home made filter holder clips to the front of each projector lens, allowing for the addition of various shades and densities of red, green and blue filters at the projection stage; this in turn makes it possible to mix the overall colour of the final image in front of the viewer, as a kind of performance / educational art piece. I've put together a video of the setup as it currently stands, which you might find interesting: [video=youtube_share;BYUIDr3-U_o]http://youtu.be/BYUIDr3-U_o[/video] And here are a couple of example images which have been scanned and recombined in Photoshop (cheating I know, but a good way to illustrate things for people that aren't able to see the projections in real life)... If anyone would like more information, I'd be happy to go into more detail. All the best, Tom.
