ADOX CHS 100 II is an ortho-panchromatic sensitized B/W film with classical grain and a sensitization optimized for grey scale 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 sheet films.
Due to the backside Layer the sheet films are retouchable with photo dyes.
In the 35mm and 120 format ADOX CHS100 II has two anti halo layers making it ultra sharp.
• Between the emulsion and the base (AHU)
• On the backside layer (anti halo, anti light piping and non curling)
The backside layer is tinted in order to protect the film against the light piping effect which is immanent to films on a polyester base. The effect was reduced to a large extend but cannot be fully prevented. Thus CHS 100 II, like any other film on PET base, has to be protected from bright light whilst the film-tongue is sticking out of the cartridge.
Or else light will penetrate through the base into the cartridge and haze the beginning of the film.
