Comparison of preliminary scanner tests

These days the DIASTOR team works on a first evaluation of the preliminary scanner tests. Here is a rough comparison of the non-standardized results from the Technicolor and the blue tinting scans.


DIASTOR conducts color analysis for CALIGARI restoration

DIASTOR is involved in the restoration of “Das Cabinet des Dr. Caligari” (Germany 1919) by the Friedrich-Wilhelm-Murnau-Stiftung in Wiesbaden, currently under way under the supervision of Anke Wilkening at L`Immagine Ritrovata in Bologna.

Based on the findings of their previous research project “Film History Re-mastered” the DIASTOR research team investigates differently tinted and toned nitrate prints regarding their color schemes and the application of the various tints and tones. Our aim is to identify the colors applied and the relationships among the different prints in collaboration with Dr. Ulrich Ruedel from the British Film Institute.

An extensive photographic documentation of the colors from the 1920s has been completed by project manager Barbara Flueckiger in Bologna. Nobel prize laureate Prof. Dr. Richard R. Ernst has conducted measurements on the Raman spectroscope. Additional measurements are scheduled for next week.

Coming soon to a screen near you: HEIDI (1978)


Initial scanning tests have been conducted at EgliFilm in Zurich to ascertain the film material’s status of the 1st episode (of 26 in total) of the immensely popular Swiss TV-series HEIDI (1978). 3K scanning tests on the Northlight scanner, from both an interpositive made in 2003 as well as from the original 16mm camera negative (1978), edited in A & B rolls, have brought some of the material’s problems to the fore. In collaboration with the advanced video technology group at Disney Research Zurich some of these issues will be adressed in the near future. Watch this space!
