Hi all,
Producing a digital negative , one can go about making a transparency, an imagesetter neg, film recorder or on on one of those snazzy Lightjet/Chromira machines to produce one.
So this is just an idea, wondering if it was at all feasible or not...or i'm just plain crazy
. Hopefully I can explain it well.
Getting a projector hook it up via the computer, say we get a HIGH resolution of 1024x1024(I know there are none just say there are). Not enough res for a decent neg if we projected that.
So how about the projection falls only onto PART of the negative. As it exposes part of the negative, the negative moves(from left to right) synchronically with a moving IMAGE PROJECTION(left to right).The projector and lens is stationary ONLY the negative and the IMAGE moves left to right. Now this is the same sort of concept as slit photography. Ok so say the images is broken into 2 parts, I could get an image of 2048 x 1024. Yes so what you say...well then lets take it one step further. Why not break the image into 4 parts and display it that way, then the only problem is registring the image correctly of the inbetween top and bottom images(I think that WOULD be the MOST COMPLEX part)! :| So if that was overcome, then why not produce an image cut up into 8,16, whatever size you want!
The machine used to move the negative would probably be done on a CNC machine with extremely small movments, X, Y Axis..
Though other issues would be the lenses, that would have no distortion whatsoever. A flat field lens could be used?
Also how would I be able to register say the top row with the bottom row?
Its a highly complex problem just something I've had in my head for some time.
Anyhow just dreaming...
