    ortho, not pan film

    i know for a long long time orth-based film emulsions were king.
    roll film, plates, and sheet film were all ortho.
    now, unfortunately there are only a small handful of ortho films out there ...

    would it be less expensive ( not b/w dyes needed ) to have ortho film made
    rather than now-traditional pan-film?

    i really like the look of orthochromatic emulsion, and would love to have choices
    other than lith film, or paper negatives.

    i have coated film base with bottled emulsion before, but my efforts
    were not very successful.
    im empty, good luck

    You could always try a blue filter on the lens.

    Maco/Rollei Ortho 25 may be something for you? It can be developed in any developer.

    Ilford still make Ortho Plus, it's an excellent film and gives the same quality as FP4, except it's spectral sensitivity, it's available as sheet film.

    Michael suggested a blue filter, I'm thinking along the same lines, but Cyan, as the true complement to Red (Blue being the complement to Yellow). I don't know if the difference would matter, but the Blue filter should hold back some yellow, which the Cyan should pass.

    A blue filter will do. It's not about being the complementary colour in a colour wheel, but about excluding that part of the spectrum ortho film is insensitive to.

    Remember, Jnanian, that ortho was King because there was nothing better.
    In the country of the blind, and all that.

    Did ortho not have some dyes?

    I thought that ortho was some dye, but not a full pan dye set.

    Of course getting my mom to talk about lovers prior to dad is easier than to get a film manufacturer to talk dye sets.
    my real name, imagine that.

    There are some Kodak intermediate/print/lab films in 35mm that are orthochromatic. Yeah, you need to buy 1000 feet of them, but they are out there. I have one 1000 ft spool I picked up cheap and need to play with when I get some time...

    What EI do you normally shoot the Ilford Ortho Plus film at? Just curious, I have never shot any Ortho film and would like to try some and see the difference. The Ortho Plus Fact Sheet states "Daylight sources ISO 80/20°" and "Tungsten sources ISO 40/17°".

    i'd rather use the real-deal instead of filters,
    i never use filters ( except for a center filter )
    and i can't stand filters ...

    maybe i will look into ilford ortho plus it seems to be what i am looking for ...

    mike:
    i don't think that ortho films had dyes in them, it is kind of like liquid emulsions you get in a bottle
    or a home brew emulsion ( bromide / iodide ) ... maybe i am wrong ? ( i am wrong a lot )
    im empty, good luck
