WOLFEN NP100 is an exceptionally fine grain 100 ASA, 36 exposure, black and white photographic film. This is one of the first brand new and professionally finished photo films launched by the company in decades, proudly still produced in Bitterfeld-Wolfen on the original site where film manufacture has been a tradition since 1910.
WOLFEN NP100 differs from WOLFEN UN54 in that it has an additional dyed antihalation layer. This layer is positioned between the base material and the emulsion layer and has the task of preventing the formation of a reflection halo.This improves image sharpness.
WOLFEN NP100 has been made available on a strictly limited run of 36,000 cassettes (36 exposures) and is right now being packaged into Industry standard DX coded steel canisters on our brand new finishing line.

Negative Film WOLFEN NP100
Product description
Negative Film WOLFEN NP100 is a panchromatic medium speed black-and-white negative camera film for both outdoor and indoor usage. an additional dyed antihalation layer. This layer is positioned between the base material and the emulsion layer and has the task of preventing the formation of a reflection halo. This improves image sharpness.
Base: Safety base, triacetate, grey coloured, 135 µm

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: 100/21°
The speed value refers to a developed WOLFEN NP100 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.
RMS-Granularity

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).
