    After 12 years of research , I learned the most amazing thing is resolution at old Leitz lenses. When I enter the gallery , I quickly identify which is Leica photograph and which is not.
    But AGFA films and papers even more amazing , they are transform a normal photograph in to a state which I liked to see with Leica , it is texture , contrast and tones.

    I asked myself , what can be responsible from that texture ? I looked to Ian and PE posts and found there was 3 or more gelatin used. I looked to Osterman site and he talks about different gelatins and different grain sizes with controlled by reheat.

    I did two things , first I applied for a new patent no 61598792 about different pigment size , multi cartridges
    inkjet printer ink to mimic grain size difference of different gelatin mixtures for to control high frequency noise , so the texture.

    Second thing is to present an one of my old ideas heated.

    I read Osterman tells that heat changes grain size.

    If we can take two 8x10 negatives , first fully developed and scanned and computer processed and
    than if we fill the 6 different canisters of HP Printer with different developers and if We reprogram the print head for different heat per pixel

    We could get faraway more control on final image.

    Best ,

    What? You want to put fill inkjet printer cartrdiges with developers and then print on...fully developed photo paper?

    You lost me completely.

    Roger , I apply this to second exposed but not developed negative or paper.

    Another person here once used regular photo paper, unexposed n fixed to print digital picutes. I never saw the results of the experiment but I would imagine it would work very nicely.

    BTW what is the average grain size of conventional and T-Grain films?.. in microns please?
