Increase the quality...

... of the captured frames can be done by post processing. A great program to do this is AVIsynth. Freddy van der Putten wrote a few special scripts for this program to enhance your movies. They convert them like you used a HD videocamera. He's put a few stunning examples on Vimeo. Have a look here.

Standard v.s. wet gate scanning

Standard scanning
Most film scanners have a standard gate or dry gate in contrast to a wet gate system. Dry scanning is a standard method where the original material is intact and is run through the film gate block. The image is rapidly captured with resolutions ranging from SD, HD, 2K and 4K.  The film is scanned as it is without prior physical manipulation to the original material.

Wetgate scanning
This type of scanner deploys liquid chemical solution that has an optical property and fills in the microscopic gaps on the film emulsion, which when scanned appear as dirt or scratches. The fluid, which has a refraction index similar to that of the film base, corrects the light rays that hit the film surface during scanning. The film is then quickly dried once it has been run through. Wet gate scanning is especially used in heavily scratched films, which also allows a more organic treatment to the film than digital retouching.

The finished projector

Although a project like this never will be finished, you can now speak of some kind of end result. Of course there is still a list of wishes like improvement of the webcam and the possibility to speed up the process by improving the frame speed. This last issue is not really related to the projector, but is more a software problem.

The photographs shown underneath give you a impression of the finished projector. If you decide to build something like this yourself, you can always start from another projector. The only warning I have to give you is that you need some mechanical and electronic skills to finish this project successfully.

The complete projector, including camera and mouse interface


The inside of the projector. On the right side near the bottom the most important part used: the earth wire. A bit more down, the runner up: the fuse.


The operating panel.

On the left the on/off switch. Next to it the switch for the LED and under that the knob for brightness control. And next the drive switch and speed control. On the right the frame speed indicator. The little switch on the bottom is used to inhibit the sync pulses presented on the connector on the right side of it.
