The results at the Digital vs. Analogue show at MONOCHROM in Berlin, two weeks before, brought positive results. Here they are.
1. a 35mm analogue film like GTP (photographed with Zeiss Ikon ZM, Biogon 2/35 with stop 4) you can compare in resolution in 20x25 inch enlargements with digital highend (PhaseOne, Leaf, etc with 72mm Schneider stop 11), of course there is some little grain in the analogue enlargement. A Gigabitfilm-rollfilm will have always a better quality than digital highend.
2. if you think in marketing categories, the professional photographer needs this quality now, because this quality is standard in digital highend.
3. to get an identic enlargement from 35er Gigabitfilm-negativs in 20 x 25 inch as digital highend prints of the same size, it is a good idea, not to look for best possible speed, but for a grain free quality. A modificated developer parallel to the new HDR-chemistry will allow this. This developer will follow soon.
4. Comparing the digital prints with analog prints in this quality class shows, that the MTF-values of the classic bw paper is not the best, but a 35mm enlargement in 20 x 25 inch is quite sufficient. For smaller enlargements it would be the best to use the better MTF-values of the AZO-paper. Now you have special enlarger for that and you will get a quality in the smaller sizes, you cannot get with any digital, because digital printing has the same resolution as normal bw paper this is my conclusion.
5. analogue can strike back now.
The next result was to find the miracle of quality control for modern emulsions, the factor X. I will prepare a further article for that, because in german on
www.aphog.de :: Thema anzeigen - Photograpie mit hochauflösenden Filmen - allgemein -
I wrote a longer article of that.
Now the gate is open for a fault-free, enhanced chemistry. The Gigabitfilm HDR chemistry you can use as universal chemistry for all monodisperse films for halftone, as 100 years ago Rodinal for the classical emulsions.
In this article I describe the effects of a unsuited velvet in a cartridge I found, this textile has unsuited contents of auxiliaries (there exist around 6000 different for textile manufacturers), this auxiliary will contaminate the film and also the camera, sometimes via the film the developing tubes. When the unsuited cartridge is taken out of the camera, the auxiliary will stay as a molecular layer inside the camera on these parts, the film has touched. The next film gets in contact with that and mistakes in developing will happen. The new generation of colour and bw films can get qualitytrouble thanks that, when you will develop in E6, C41 or bw like D76.
