Storage
| Raw Stock : | up to 12 month: | 18°C or lower |
| more than 12 month: | 13°C or lower | |
| recommended relative humidity: | 50 to 70 % | |
| Exposed film : | process as soon as possible | |
| Processed film : | store 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 such as sulphur dioxide and hydrogen sulphide, formaldehyde vapours, radioactive radiation, and X-rays have a negative influence on films.
Warranty: 24 months provided the storage conditions specified above have always
been observed. Exposure index : ISO 100 / 21° The speed value refers to a developed UN 54 average gradient of 0.65. The exact exposure
index depends on the prevailing shooting and processing conditions.
Special features of light meters, shooting conditions, planned artistic effects and deliberate processing changes are to be taken into account in setting the lens aperture. Rehearsal screen tests are recommended. Darkroom lighting: UN 54 should be processed in total darkness. If absolutely necessary, a safe light using an indirect 15 watt lamp can be used while processing, having an ORWO safe light filter no. 108 (dark green), Kodak no. 3 or Ilford no. 908, but a distance of at least 75 cm should be maintained.
Processing
As Negative Film according to ORWO instruction 1182 (D96) to a recommended average gradient of 0.65. As Reversal Film according to ORWO instruction 4185 to a gradient of 1.1 RMS-Granularity : A average value of 12 ( read at a net visual diffuse density of 1.0 above the minimum density using a 48 µm aperture)

Comment
If you want to receive a very fine graininess we suggest the developer, mentioned down, but you have to expect a little bit less in sensitivity, too. If you are depending to the real sensitivity and a normal fine graininess we suggest you to process according to ORWO Instruction no. 1183 with the phenidone-developer. Depending on the processing equipment, deviations of time and temperature are practicable, if a comparable processing quality is guaranteed. Lower temperatures for spray-washing are practicable too, if the washing time is extended (i.e.30 … 40 % at 12 …15°C).
