    Rollei R3 Film and Pyro; 8x10 R3 film

    With reference to Rollei R3 film, I wonder if anyone might have some answers to the following questions:

    1. Has anyone used Pyro to develop Rollei R3 sheet film? If so, might you be kind enough to supply the parameters you used ( I have a Jobo CPP-2 and will use the expert tanks ) such as time and temperature? Also, might you be willing to share your observations as to the results versus results obtained with other developers and Rollei R3sheet film?

    2. I can purchase R3 in 4x5 from several sources. Is 8x10 R3 still available, and if so, from whom?

    Thanks in advance for any guidance.

    Edwin

    In their own price list from March the Mahn company (Maco) offers the R3 in two package sizes in 8x10.

    Staining and tanning are side effects of pyro (correct me if I'm wrong).

    R3 is a 3-layer film reported to be not workable with surface developing chemistry.
    Wouldn't a tanning developer hamper the thorough development through all layers?

    Yes, after all staining developer add colour to B&W negs :-)

    Yes staining and tanning are the reasons people use Pyro developers, rather than a side effects.

    Needs a Mod to move it to the B&W section. Or a Council member to wake a Mod up :-)

    Exposing the R3 as low ISO and developing in T&S developer as tanol is reported to work well in the technical documentation, but what's the point on it?

    Precisely why I asked.

    Thanks.

    From the R3 data sheet:

    This is where the special features of ROLLEI R³ come in.
    By proper choice of the developer, the user has unprecedented control over the result.
    Experience has shown that photographers’ first trials of Rollei R³ frequently were unsatisfactory.
    This is why we would like to provide some basic information directed at both photographers and darkroom technicians:
    The new ROLLEI R³ is a multilayer film. It therefore calls for comparatively strong exposure if it is to be processed in a professional laboratory instead of by the photographer.
    In “home” processing, prewashing is essential.
    ROLLEI R³ will give unsatisfactory results if development was too short in relation to exposure.
    The following should therefore be noted:
    Too short a development will give rise to very coarse grain and very thin negatives – in short, an unsatisfactory result.
    If development was – within certain limits – too long, however, no photochemical drawbacks will be encountered, except perhaps for steeper gradation and, as a result, minimization of the extremely rich tonal rendering.

    We can just underline these remarks.
    Best results I had indeed with the RHS/AM74 (1+7 - 1+9) and RLS/CG512 (1+4) developers.
