ADOX films are produced in 35mm, 120 rollfilm and in sheet film formats. The rollfilms are delivered in re-usable containers which guard against fogging and protect the film during transporting. For large format workers grain in large scale negatives is less of an issue but here the advantage of the ADOX films really come to the fore with with sharper, richer tonal scales.

For best results with the 25 and 50 films, exposure them at their rated speed and don’t over-expose. The processing temperature should be held as close to 20° C as possible. These films are should be processed by hand, preferably not in a machine and definitely not by commercial processors as the delicate emulsion is easily damaged by machines designed for bullet-proof colour films. The use of a hardener in the fixer is recommended but not absolutely necessary. With sheet films, a pre-wash of 1-2 minutes in water is necessary to remove the protective gelatine layer.

ADOX CHM Professional Films

The CHM series films orginate in England and are packaged for ADOX. The CHM films differ from the original CHS films as they use multiple layers and possess a very robust emulsion highly resistant to exposure errors and mechanical effects.

In contrast to the CHS films (which should be hand processed), these films can be processed in any commercial or high street shop since the developing time are identical to FP4 and HP5.

CHM film are very easy to use and flexible. The 400 particularly exhibits a very wide exposure latitude – from 100 to 1600 ASA with suitable developers. The 120 rollfilms are delivered in the ADOX branded protective containers which protect against light ingress through the sides of the film and keep the film safe from physical damage.

ADOX Display Film

A lith film with halftones on a clear base – a transparent photopaper – with many application areas.

Orthochromatic (not red-sensitive so you can handle it under a red safelight) emulsion which behaves very similarly to a normal photographic printing paper, but which is on a clear base and therefore absolutely ideal for producing large negatives for contact processes such as Cyanotype, Salt, Palladium, Platinum and so on. Can be used as negative film in large format pinhole cameras. The film has a speed of around 25 ASA. With a negative in the enlarger a positive will result which may be projected or backlit.

The contrast can be altered according to the application by the use of different developers and dilutions. This is important for some Alternative Processes (Cyanotype, Salt, Albumen) as a greater density and contasty negative is needed.

ADOX PAN 25

The PAN 25 film is a modern technology film with a very fine grain emulsion coated on a clear PET base for archival permanence and structural stability. A highly effective anti-halation layer is coated between the base and emulsion while an NC (anti-curl) layer is coated on the rear of the base to improve handling and film transport in the camera. Spectral sensitivity: 400 – 650nm. Developing times for most fine-grain developers are 4-6 minutes. D-76/ ID-11 Stock: 5 min.

Orthochromatic films exhibit extreme sharpness and the finest grain but are blind to red light which imparts a unique ‘Look’ to the final image – Ortho films pre-date panchromatic films so if you after the vintage feel, this is the one to use. The ortho look is accentuated by high contrast developers such as Neofin Doku, Maco Docufine, Technicol etc but ATM49 also works well.

ADOX CMS 20

With CMS 20 high resolution film ADOX rounds off its line ordered by grain characteristic and layer construction.  Cubic Crystal Monodispesed Single Layer means round silver grains coated one layer a single grain thick. Since this is the smallest grains of silver that technology can produce, the film has the highest resolution, the finest grain and is the sharpest film in the world.  It belongs however to the toughest and slowest emulsion in the stable. The Anti-Halation layer between the emulsion and the film base guarantees sharpness, the ADOTECH CMS developer yields true to life halftones enabling you to make pictures that no-one will believe were taken on a 35mm camera!

Orthopanchromatic sensitivity with a spectral distribution that differentiates colour nuances – CMS “sees everything” – no green filter necessary with portraits. CMS resolves 800lp/mm greater than even the Kodak Imagelink or Copex and is about 4 times the resolution of Tech Pan.

efke R100 127

The only 127 black and white film still available the efke R100 127 has the same emulsion as the Adox CHS 100, being made in the same factory. Fits the ‘Baby’ Rollei 4x4, Kodak Brownies etc still in widespread use. The backing paper is not as thick as that used in 50’s and 60’s so for cameras with the little red window at the back put a bit of black tape over the window to prevent light passing through the backing and fogging the film (you also get the numbers on the backing paper appearing on the negative). Lift up the tape so you can see the frame numbers to advance to the next frame.

efke IR820 Infra Red

The efke IR820 Infra Red film is a true Infra Red film with extended spectral sensitivity to 820nm rated at a nominal 100 ISO without filter. Recording Infra Red radiation creates unworldly artistic effects, clouds, foliage and warm skin tones appear white while blue sky and water black. Most panchromatic films are sensitive to light wavelengths from about 400nm- 700nm, which is enough to record what the eye can see. Longer wavelengths are invisible to the eye but not to this film: its Extended Spectral Sensitivity enables it to record wavelengths as long as 820nm, well into the Infra Red.

To get the best results, a filter is needed; deep red or special Infra Red filters block out the visible portion of the spectrum letting the IR wavelengths pass to be recorded on the film. The deeper filter the more of the visible is blocked, but exposure times increase and with very dark IR filters it is not possible to use camera metering. Using a Heliopan 665 filter results in a reasonable balance between usable film ISO, so you can even expose handheld, recording Infra Red with sufficient of the visible spectrum blocked with the ability to still use camera metering. A Heliopan 715 will give much increased Infra Red being recorded but with extended exposure times and the need to determine exposure manually.

Adocolor 126

Adox Adocolor 126 cartridge contains a 200 ASA colour print film with 24 exposures. Processing is standard C-41.
