ORWO TF12D - 16MM
No longer available
ORWO TF12d has been designed to meet critical technical standards being demanded today by sound recording professionals. It is a black and white film of orthochromatic sensitivity, being characterized by superb quality attributes in high contrast,super fine grain, and ultra high definition.Accordingly, the design is ideal for use with both digital and analogue technologies. It has theoptimal spectral sensitivity necessary for high quality digital sound recording with DOLBYSR.D or DTS time code systems, and also for optimum exposure with incandescent and laserlight sources being used in existing analogue sound recording.The best possible degree of sharpness has been guaranteed by introducing a new AHU layer located between the film’s clear base and its emulsion, and this clarifies to neutral during processing. A permanent anti static layer between the base and the AHU layer and an antistatic backing to the film supplies protection from dust and static discharge, while also improving film transport efficiency.

Product description: ORWO TF 12d has been designed to meet critical technical standards being demanded today by sound recording professionals. It is a black and white film of orthochromatic sensitivity, being characterized by superb quality attributes in high contrast, super fine grain, and ultra high definition. Accordingly, the design is ideal for use with both digital and analogue technologies.

The best possible degree of sharpness has been guaranteed by introducing a new AHU layer located between the film’s clear base and its emulsion, and this clarifies to neutral during processing. A permanent anti static layer between the base and the AHU layer and an anti- static backing to the film supplies protection from dust and static discharge, while also improving film transport efficiency.

| more than 12 month: | 13°C | |
| recommended relative humidity: | 50 % | |
| Exposed film : | process promptly | |
| Processed film: | storage at 21°C or lower with 40 to 60 % relative humidity for normal |
periods; long term storage according to the standards ISO 5466, SMPTE RP131 and ANSI IT9.11. Substances as sulphur dioxide and hydrogen sulphide, formaldehyde vapours and radioactive radiation have a negative influence on films.
Warranty : 24 month subject to the a.m. storage conditions.
Processing: According to ORWO instruction 2182 (Kodak D97) / ca. 5 min Process promptly after exposure.
Exposing
Analogue sound track : The aim density of sound negatives and prints should be determined by a cross modulation test. The normal analogue visual negative density is between 2.20 und 3.30. Digital sound track : The aim densities of negatives and positives are determined by making a series of density tests. The densities with best results by Dolby-quality-index should be select. The aim density for negatives and prints should be around 1.30.
Characteristic curve TF 12d: Processing ORWO instruction 2182 (Kodak D 97)
Modulation transfer function m
Relative spectral sensitivity TF12d
Darkroom lighting: Films should be processed in total darkness. Do not use a safelight.
