Acros 100, pinholes, and development compensation

[ndavidson2]

I have searched data sheets, google, and other forums for this information, but I haven't found anything pertaining to development compensation for long exposures for Acros 100. I want to try Acros in 4x5 for it's nearly non-existent reciprocity effect, but would like to know at what exposure times would require N-1, N-2, N-3 development. Not sure if it matters, but most likely I will be using Rodinal as the developer.

Thanks!

I've developed hundreds (?thousdands?) of rolls of ACROS in Rodinal.
Never tried screwing with development times.

The datasheet graphs show you exactly what to expect with different times.
It's called "gamma".

ACROS really does have almost zero reciprocity failure, as the datasheet says.
