35mm film, sharpness & fine grain

Here you can find a brief description of all our developers:
Dead Link Removed

Indeed CG-512 is a liquid depth developer more or less a liquid alternative for Microdol-X and/or Perceptol (TM)
However it will produce the same fine grain it will give slightly more sharpness. Disadvantage is the 24 degrees C. development temperature and the limited lifetime. Dilution 1+4, one of the reasons we are selling them in 250ml bottles only. Rollei is selling them in 1 ltr. Silar (TM) bottles. You can prolong the lifetime of this developer by keeping it very cool (4-6 degrees C.)
No particles will fall out like some other type developers.

On our website you will find extended data sheets for all mentioned developers, partial English, German and Dutch. For Amaloco we can provide on request German, French or Czech/Slovak translations.
SPUR is from Heribert Schain (Langerwehe, Germany). Very good developers especially on modern emulsion type films like Acros 100, Delta and Tmax type. Even the Fomapan T200 (based on some Fuji technology) is doing rather good with these German developers, unfortunately quite unnkown, even in Holland. You can compare the situation with Paterson developers from Crowly. The marketing is THE problem. Paterson developers are hardly used overhere (=Netherlands) but I know some of them are pretty good (Like the SPUR).

If you want we can provide you some samples. Then you can see the results yourself. High definition you can not see on any monitor and the scanner should be a top product to prevent some loss in the process of digitalisation. Directly from the negative to a big format is the right way to go and compare things.
Here is the website from SPUR for further information:http://www.spur-photo.de/

For more information, please do not hesitate to contact me, preferable by e-mail.

Best regards,

Exposure and development also affect graininess. Too much of either is bad. Too much of both is really bad.

I totally agree Patrick, the minimum required exposure for discernable shadows and minimum development to obtain a full tonal range. More exposure than is necessary increases graininess and lowers sharpness and resolution. I have an old copy of Popular Photography magazine which is a special issue for `Sharpness and how to obtain it`. ( August 1961). It suggest that 35mm films should be exposed and processed so that the majority of negatives print well on grade 3 papers rather than grade 2 for optimum sharpness and resolution.
I must try your developer recipes soon.
Cheers.

I have posted these links of which photographers may find interesting on how some films may perform better in certain developers than others.

Fred Picker said that, too. I process all my 35mm film for printing on grade 3.
