Adox CHS 100 II - 120

ADOX CHS 100 II is an orthopanchromatically sensitized B/W film with classical grain and a sensitisation 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 sensitisation it features a very harmonic tonal separation.
Compared to modern films it differentiates better between lips/face, clouds/sky, and 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 achieve a medium contrast of 0,65 reduce the sheetfilm developing times by about 10%.

Films coated onto PET are subject to the lightpiping effect and must be loaded in the shade.

Rollfilms tend to spring open so they need to be held even more tightly than triacetate films when loading into the camera.

Tanning developers (Pyrogallol / Brentkatechin) are not recomended for Films with an AHU as they can cause tiny emulsion liftoffs.
