Ultra-fine grain, very high contrast, a rich tonal range with deep blacks and bright whites. Requires the special SCALA process.

B&W slide film is a photographic curiosity — instead of producing a negative, the film directly produces a B&W positive that can be projected or scanned. The Adox Scala is the successor to the Agfa Scala (discontinued in 2004), created by Adox to keep this unique process alive. Its special SCALA process requires an equipped lab or a two-bath home development kit.
