One of the reasons why CHS 100 had to be discontinued in 2012 was the unavailability of the spectral sensitizer.
We have tried to match CHS 100 II as closely as possible to the old film featuring:

  • a rock solid classic emulsion system which has been out there for decades
  • a sensitization close the one of the old CHS 100
  • a single layer emulsion
  • the same base material including the option of reversal processing
  • an optimized backside coating to fully prevent light piping if film´s loaded in subdued light
  • a special anti halation layer between the emulsion and base for enhanced sharpness
  • a full set of formats from 35mm to ULF including 120
  • a state of the art cascade coating avoiding all problems associated with older CHS100 productions

The new film is manufactured in Germany and thus upgraded to our professional line.

ADOX CHS 100 II B&W Film

ADOX CHS 100 II is an orthopanchromatically sensitized B/W film with classical grain and a sensitization optimized for greyscale separation.
The film is made from two separate emulsions in a single layer coating and yields a very large exposure latitude.
Due to its classic sensitization it features a very harmonic tonal separation.
Compared to modern films it differentiates better between lips/face, clouds/sky, water/land.
The film is coated onto clear archival PET.

ADOX CHS 100 II and can be reversal processed (including the sheetfilms).
Due to the backside Layer the sheetfilms are retouchable with photo dyes.

In the 35mm and 120 format ADOX CHS100 II has two anti halation layers.

• Between the emulsion and the base (AHU)
• On the backside layer (anti halation, anti lightpiping and non curling)

Due to the extra AHU layer in the miniature and 120 format there are slight differences in the developing times between those films and the ADOX CHS 100 II sheetfilm.
In order to achive a medium contrast of 0,65 reduce the sheetfilm developing times by about 10%.
