    Ortho Films?

    I'm running out of my stocks of Kodak Contrast (Process Ortho), which I shoot at ISO 12 and DBI. I'm looking for a 4x5 replacement. ISO isn't much of an issue, since they're basically all ISO 100 or slower.

    As far as I can tell, this is what's out there:
    • ADOX ORT25
    • EFKE PL 25 ORT (Same as ADOX?)
    • Rollei Ortho 25 (Same again? These three are all FK, no?)
    • Ilford Ortho Plus (Gone from Freestyle website...)
    • Maco/FK PO 100c (I'll have to call freestyle about this one...)


    Are there others I've forgotten?

    Does anyone have experience with any of these? I was hoping to get a little input, advice, recommendations, or cautionary tales before I run out to order a bunch of different ones. If it comes to that, then I will, and test them all.

    Thanks in advance for any advice.

    How about films more sensitive to blue, even though they may be pan films?

    Something with a higher speed such as 100ASA or higher?

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.

    Failing a good ortho film what would be a good filtration to simulate ortho's sensitivity?

    I've used an 80B filter on the camera lens with pan film. I believe you can get bluer, but an 80B will give somewhat of an ortho look w/o too much trouble.

    One of the biggest reasons I like shooting ortho right now is developing by inspection, which I can't continue to do under red safelight if I simulate ortho on a panchro film. Ideally, I'm looking for a true ortho replacement.

    I have only experience with the Ilford film, which as far as I can tell basically is FP4 with an orthochromatic emulsion. It works very well, is consistent, easy to handle but quite expensive.

    May or may not fit your exact requirements, but Freestyle's APHS, which is primarily designed as a graphic arts film, may work. Abundant in various sizes, and is very inexpensive. Development under a red safelight is also built in. There are many posts here about how to process APHS in different developers for different applications, including in-camera shooting. My estimated EI for APHS in bright daylight is about ISO 4 or thereabouts.

    I've though about APHS, but I'd prefer regular ortho to ortho lith for the tones. I may give it a shot anyway.

    I have tried the efke ort25 in 35mm.
    it took me a few tries to get the contrast ok.
    With the contrast tamed this is a film i will
    use for the proper subjects.


    i have not tried the other ones mentioned.
