MACO Cube Film was [APML] Print films for AP (Long)
Here is a Google translation from the MACO German web page regarding this
film. It seems to have all of the properties we are looking for in a high
speed film. Now, what are its reciprocity characteristics? Jim
http://www.mahn.net/Frameset.htm
MACO CUBE 400c short description/processing Price cunning up to 500 years
durability (LE500) (certificate R.I.T smelling ester of institutes OF
Technology of 16.09.1998 for polyester basis with silver gel emulsion)
two-layer film. Finest cubic silberhalogenide for the sharpness, larger for
sensitivity. Characteristic: 2-Schicht-Emulsion. Halation protective
layer on the film basis. This is responsible for a sharpness gain. (a
further characteristic is that this halation protective layer separates
perfectly in the developer, no grey colouring of the film). By this coating
technology can Unschaer be fen by light scattering in the layer lastingly to
avoid. Process control by developers: The negatives are characterised by
very fine grain and unusual sharpness during clay/tone value wealth
differentiated at the same time and very fine light design. Since it
concerns a layer depth film in contrast to the duennschichtfilmen otherwise
offered by MACO, the emulsion responds more differentiated to developers.
Developers such as KODAK Xtol or LABORATORY PARTNER CUBE XS need for a very
long time, in order to reach a maximum density and approximately nominal
sensitivity. Also with a ueberbelichtung, e.g. on 200 ISO, those are
reduced very long development times not substantially. The result are
tender, fine-grained negatives with a nearly ideal course of the curve. To
manufacture itself these own ideally around large enlargements. We leave
now the technology and come into the range of the personal taste: Each
photographer has other opinions for the conversion of his work. That, which
specialized in very fine grain, still high sensitivities wishes and on
long-term stability of its filmmaterials attaches importance, which is with
KODAK Xtol and LP CUBE XS serves exzellent. Developers such as MACO
ecoprint/ecotol and LABORATORY PARTNER SUPERGRAIN (about 50% finer grain
than ecotol) the KODAK HC 100 are very well suitable, in order to supply
with quite short development times strong negatives. The nominal
sensitivity of 400 ISO is problem-free reached. In particular LP-supergrain
much edge sharp a struktuiertes grain develops. The result are strong
negatives with a steeper course of the curve. Also these negatives are
outstanding suitable for the preparation of large and largest enlargements.
With this chemistry then the grain (and/or the gaps to be around more exact)
serves as picture-formative means. There are photographers, who use this
kind of the organization. In particular ecotol is ideal for "grain
organization". Only layer depth developers, as LP-supergrain are suitable
for the contrast price increase, this are important for all users of the
zonensystems. Characteristic = INFRARED RANGE due to increased red light
sensitivity (the curve begins with 730 Nm and ends with for instance 750nm)
should take place inserting the films in principle with absorbed light. The
langzeitlagerung is possible with for instance 13°C.. For infrared
processing everything actually applies, which you know about infrared
films - now an IR film with 400 ISO and a high reserve is only, available.
The CUBE 400c is ideally suitable, in order to work during a photograph
series at the same time with and without infrared filters. Like that
"normal" photos and IR photographs are possible e.g. on a film, without this
influence on the film development would
ave. ----------------------------------------------------------------------
