"celà laisse présager de bonnes choses pour les quelques amateurs d'inversion ."
L'intervention complète sur APUG :
As far as the usability of the CMS film as a slide film is concerned there are two factors in favour of this and one is questionable at this time of testing.
What basically makes any b/w usable as a slide film is the clearness of the base and the effectiveness of the antihalation layer.
Practically any b/w film can be reversal processed just if you end up with a blueish base (or a clear base but uneffective antihalation layer) your projected images might be dissatisfying.
These two criterias are met with our new film in an excellent way thus we suggest it for this alternative use as well. It comes on a perfectly clear base and it has a superb antihalation layer which is actually located between the emulsion and the base material, thus eliminating any halation effects caused by the base material itself.
If reversal developed this film will show brilliant slides with no visable grain up to over 2,5 meters projection diameter.
Especially if intended for projection, results of CMS, reversal processed to a slide, should be superb.
However since it is based on a microfilm technology we have not yet been able to make enough tests about gradation control if used together with a reversal process.
First results with the Foma slide processing kit are promising but we have not determined yet at which speed it can be actually shot if used for reversal process.
This is the third factor, the questionable one.
We plan to intensify our test on this in the first quarter of 2006.
Until then we are busy with the production and the final tests on this material in regular use as a negative film.
