    I wouldn't be suprised if this WAS PE's.

    It is not mine. I may have access to one similar to it later this summer.

    this guy needs to be followed by a film crew to document this, it is fascinating and PhotoEngineer needs to be flown out to Oz to contribute and develop a new "APUG" film ...

    This is the most interesting post I have read in ages, I hadn't a clue how film was made until reading this .... I am certainly thinking of visiting Ilford Harman factory if possible when next tour comes along....

    Thanks to All for their contributions

    Yeah, it's cool, and don't forget that this is just the coating machine. You also need to make the emulsion you are going to coat. It needs also much work and much hi-tech machinery can be used.

    Please note that this work seems to have stopped. There is no further information on this anywhere.

    No. It will take a while for this to happen I guess.

    Also, there is the matter of getting film support. We don't seem to be able to get any so getting the machine is a moot point if this turns out to be true.

    Maybe we have to start subbing the base by ourselves. Plastic like PET will always be available for many purposes.

    I noticed (by accident) that ammonia dissolves PET. Maybe it could be used in the subbing layer for PET .

    PET is often "subbed" by electron bombardment followed by a layer of gelatin with hardener. Or, PET is coated directly with the bombardment in a sequence called ILEB (In Line Electron Bombardment).

    Other supports are often subbed by an organic polymer, a solvent and which is mixed with acetic acid which is then coated and evaporated evaporated. Gelatin is placed on top of this.

    Ammonia and most other alkalis dissolve gelatin by denaturing or hydrolysing the amino acid links.
