1. Perutz Black & White Films

The German firm of Otto Perutz was established in 1870. It was the first to produce a roll film for the Leitz camera.
Up to 1939 it produced a range of miniature and roll films for the UK market, but the supply was interupted by WW2. In 1951, the black & white film Perutz Persenso became available again.
In 1951 it was distributed (maybe imported) by 'Milbo Trading Ltd', Ascot House, 52/53 Dean Street, London W1.

The 1957 manufacturer's address was Otto Perutz, G.m.b.H. Munich 25, Kistlerhofstrasse 75 – 82, Germany.

The 1958 address was Perutz Photowerk, G.m.b.H. Munich, Germany.

In 1959 the UK distribution of Perutz films was taken over by Hanimex (UK) Ltd.

In the late 1980s the processing address was Perutz D-8000 Munchen 70.

An entry in the “Colour Materials for Still Photography” section of the British Journal of Photography Almanac (BJPA) for 1957 lists 'Perucolor Reversal', a transparency film made in 120 and 35mm sizes. It is a daylight film with a speed rating of 20 ASA. No artificial light version is listed. Processing is by the manufacturer. This film was presumably on the market for a short time from 1955 to 1956.
The address is given as: Otto Perutz, G.m.b.H. Munich 25, Kistlerhofstrasse 75 – 82, Germany.

There are no Perutz colour films listed in the 1958 BJPA.

The BJPA for 1959 mentions 'Perutzcolor C18' film, a transparency film dating from 1958. It is a daylight type 35mm film of 50 ASA.
'Perutzcolor C14' film was an 8 mm cine, double width, film of 20 ASA speed, available about 1961.

Processing of these films was included in the price, with films being necessarily returned to Perutz for processing.

In the British Journal of Photography Annual (BJ Annual) for 1965 there is a full page advert for 'Perutz New C18' film, still of 50 ASA speed. Maybe this was an improved type.
This film is still listed in the 1968 BJ Annual but the name had been simplified to 'Perutz C18'. It required manufacturers laboratory processing, though a processing procedure is given in the 1968 and 1970 BJ Annuals. It is much the same as Kodak's E3, but with different times. This procedure is attributed to Ernest Gehret and dates to September 1960.

Notice that Hanimex are the UK distributors and processing is done in England. Slides are returned in Plastic Mounts.

Processing Perutz C18
The following processing sequence for Perutz C-18 is taken from the British Photography Annual for 1966, but apparently dates from 1960.
It is very much like the E3 process, apart from the sequence timings.
Total darkness for the first three steps. White light after step 3.

By 1973 the film name had changed to 'Peruchrome C18', though still capable of being processed by the same 1960 procedure (above).

The name had changed again, to 'Peruchrome C19', by 1976, with 126 and 135 film sizes available and with a slight speed increase to 64 ASA. As far as can be ascertained, the same 1960 processing procedure still applied. 'Peruchrome C19' was still listed in 1982.

By 1984 it seems Perutz transparency film was capable of being processed in Agfachrome processing solutions, as used for Agfachrome films 50S, 50L, 100, and Agfacolor CT18, CT21, and CK20.
It may be that Perutz never made an E6 version.

The 1977 BJ Annual lists 'Perucolor' colour negative film, with an 80 ASA speed rating and available in 110, 126, and 135 sizes. It was processed in the standard Agfacolor negative film process chemistry.
This may have been the first negative film Perutz made.

By 1982 the Perutz colour negative film was known as 'Perucolor 20', still at 80 ASA.

In 1984 the colour negative film was then known as 'Perucolor 100', of 100 ASA speed, and was processed in standard (Kodak) C-41 chemistry.

Perutz colour negative film is not mentioned in the BJ Annual for 1987 but Michael Talbert recalls using a roll of Perutz PR200 film in 1988. It was a 36 exposure 35mm for process C-41 rated at 200 ASA. The address on the green and black film carton was Perutz D-8000 Munchen 70. The negatives (still available) look much yellower than equivalent Kodacolor negatives of that time, which look pink. Also, the film is edge frame numbered up to 72, unlike the Kodak equivalent whih used 'A' numbers, e.g. 24 followed by 24A.

There is no known Perutz colour printing paper for their negative films.

Perutz films in the early 1930s were Perutz Pergrano, Perutz Perpantic, Perutz Peromnia and Perutz Rectipan.
Rectipan was about 12 ASA and Peromnia was about 25 ASA. To compare with modern films, these speeds can be doubled because they (then) incoporated a one stop safety factor, as introduced in the early 1930s for almost all black and white films.

Perutz films in 1939 were:
Perutz Pergrano: 21 Scheiner, about 10 ASA.
Perutz Neo Persenso: 26 Scheiner, about 32 ASA.
Graphic B: 12 Scheiner, about 0.5 ASA. This film was most likely a blue sensitive film possibly similar to a Process or Line film e.g Kodak Fine Grain Positive film, which was a blue sensitive 35mm film that could be handled under a bromide paper safelight, Wratten Series OB. It could be used to make negatives from colour transparencies.

In the BJPA for 1952, in the 'New Goods' section, there is a test on Perutz 'Persenso' orthochromatic roll film. In the 1930s this film was known as 'Perutz Neo Persenso'.
It was found to be a high grade film, rated at 40 ASA, with low background fog.
Test exposures were carried out using a Voigtlander Bessa camera at exposures between 1/10th second at f8 to 1 /25th second at f16. It was developed in BJPA's own MQ Pyro formula, diluted 1 to 4 of water.
All the negatives were printable, with the correct exposure being 1/25th second at f8, under a bright cloudy November (1951) sky. The test exposures represented considerable over and under exposure, but gave negatives of excellent printing quality, evidence of the wide and useful latitude of the film.

The film was numbered on the rebate 1 to 12 for 2¼ inches square negatives and also 1 to 16 for the half 2¼ by 3¼ inches negative size.

It cost 3 shillings and 3 pence plus 1 shilling and 6 pence purchase tax i.e. 4s and 9 pence (4s.9d = 24p) per 120 roll.
The 35 mm size was also available.

The film was distributed (maybe imported) by 'Milbo Trading Ltd', Ascot House, 52/53 Dean Street, London W1.

Perutz were manufacturing many black and white materials in the 1950s.

The BJPA for 1954 lists as many as seven different glass plates, including one called 'Silver Eosin'; also a 35mm black and white reversal film rated at 15 DIN, about 25 ASA.

Verbatim from January 1959 article :

The firm of Otto Perutz of Munich is well known on the Continent as manufacturers of first-class sheet, roll and miniature films and was one of the first to make and pack special films for the Leica. MCM. has a long experience of Perutz films, for they were first reviewed in our January 1937 issue, just 22 years ago!

The British agency for Perutz film has now been acquired by Hanimex (U.K.) Limited, who have sent us examples of Peromnia 25 both 120 and 35 mm. cassettes and reloads; Peromnia 21 also in both 120 and 35 mm., Perpantic 18 in 120 size only, Perpantic 17 in 35 mm. only. The numbers printed on the cartons represent the new German way of indicating DIN speeds, the stroke and the 10 degree marking now being abandoned. Thus Peromnia 25 is rated at 25 DIN or 250 ASA; Peromnia 21 at 21 DIN and 100 ASA; Perpantic 18 at 18 DIN or 50 ASA; Perpantic 17 at 17 DIN and 40 ASA; and there is also a Pergrano 14 rated at 14 DIN and 20 ASA which is not included in those sent to us for review but which we have used on previous occasions with success. It is characteristic of all these films that unlike the usual 35 mm. films which depend for their antihalation properties on the grey base, the Perutz films now have an opaque black backing which is bleached in the developer and by the time the film has gone through the fixing bath has entirely disappeared. The improvement in anti-halation properties is quite noticeable in subjects with strong light sources included in them.

All of the films have been improved in the last few years. The Peromnia 25 is extremely fast and is intended for artificial light work, having a considerably increased red sensitivity for this reason. This is indicated by the fact that with a bright red filter in daylight the factor is only 4 whereas with the Perpantic 17 the factor is 5. Peromnia 21 is intended as a general purpose film of a fast type while Perpantic 18 in roll film form and Perpantic 17 in 35 mm. emulsion are medium contrast emulsion films fully adequate in speed for most purposes. The Pergrano 14 is an ultra fine grain very thin emulsion film for those who require the maximum resolution and highest acutance.

It is worth while pointing out that the Perutz 35 mm cassettes are of very high quality, being made of plastic and easily refillable. Our tests of the whole range of films showed excellent gradation and quality throughout the exposure range with the developers recommended and it is interesting to note that development times are given for D.76 and Microdol as well as for Perutz's own developers.

Prices for Peromnia roll film (120 or 620) is 3s.1d (15.5p); 7s.0d (35p) for 36 exposure cassette; 5s.3d (26p) for 20 exposure cassettes; 5s.3d (26p) and 3s.8d (18p) respectively for 36 and 20 exposure daylight reloads. The prices are the same for the rest of the films except that Peromnia 21 and Perpantic 18 are 2s.l0d (14p) each for the 120 and 620 spools. It should be noticed that we have deliberately referred to "daylight reloads" as the normal reloads for 35 mm. films have to be inserted in the darkroom. These daylight reloads have their own centre spool and an opaque paper leader. To reload a cartridge it is only necessary to remove the cap, take out the used spool, and drop in the daylight reload, removing the paper leader to get at the tongue of the film. This daylight loading is naturally a great convenience for one saves 1s.9d (9p) by using the original cassette. This refill fits Leica, Contax and Shirley-Wellard cassettes.
