N+, N- development with Scalagreenspun.com : LUSENET : Large format photography : One Thread
This may sound like a begginers question because it is. Does the push and pull process with Agfa Scala work similar to the N+ or N- development with the zone system? I know the image would be darker or lighter, but would this achieve a similar effect?

Think of Scala (or other B&W films developed through the .dr5 process) as a transparency, which is what it is. Expose the film as if your working with color transparency material, although you can use B&W filters. The zone system doesn't work in the traditional sense. Just like color transparency material, underexposing and pushing will increase contrast, and overexposing and pulling will decrease contrast.
