Spursinn HCD and Spur Modular UR New developers

[lynnb]

RFF member Koolzakukumba (Bruce Robbins) on his blog The Online Darkroom has published a Q&A interview with Spur's Heribert Schain, about their two-bath developer Spursinn HCD. There is also a comparison of 35mm Spur Ortho film developed in Spur Modular UR New, and 4x5" T-Max 400 developed with SPUR HRX-3 New.

Both these developers sound interesting. There seems very little mention of them elsewhere on RFF. If you have any experience with either of these developers please feel welcome to share them here. Sample image scans are welcome.

SPUR (Speed Photography and Ultra high Resolution) is working in a very small market. They are popular in Germany and for the rest only in specialized areas.
They are making for example the ATP-DC developer for Rollei, also using a kind of micro film from Agfa Gevaert (Rollei ATP1,1) but with extended Red sensitivity.
An Orhopan micro film version from Agfa Gevaert they are using themselves and Adox (CMS 20) and also here a dedicated developer.
A special dedicated push developer for the Rollei RPX 400, called RPX-D, made by SPUR, indeed E.I. 1600 works!
The Adox Silvermax, more or less a copy of Agfa Scala 200, putting in the cine film from Adox and with a dedicated developer (yes, also from SPUR) usable as negative 35mm film.

Pointing out to the ultra high resolution films which is their speciality here an example of the Rollei ATP1,1 with ATP-DC E.I. 25. Trying the same film in a high diluted Rodinal/R09 1+150 you will hardly get iso 15 and still problems in contrast with the negative.
Testing out some ATP1,1 combinations you can also use the Rollei Low Contrast formulae 1+5 with the film (An Udo Raffay formulae) but also on a lower E.I. A bit better then the Rodinal/R09 1+150 combination.

Rollei ATP1,1 in ATP-DC, E.I. 25.
M7 + Summarit 2,5/75mm.
ATP-DC is a SPUR product.
