The Adox CHS 100 II Black and White Negative Film is sensitized for ortho-panchromatic use, with a traditional grain structure and single-layer emulsion that provide excellent tonal separation and highlight control. With a nominal sensitivity of ISO 100/21° and dual anti-halation layers, this film delivers sharp images with minimal grain. The two-part single-layer emulsion allows for greater tonal variation and a wider exposure range than modern emulsions. This film can be developed as a negative in standard black and white chemistry, or as a reversal process for black and white transparencies.
