Dear Andrew,

Thank you very much for this contribution.

One Question to your sketch

The base exposure is the shortest exposure to achieve black in the clear parts of the negative. The first image in your sketch is not the base exposure but already a post-exposure with 30 s without filtration and 10 s dodging? Right?

I work with the Heiland Splitgrade system, which you probably know.

The controller usually gives me the shortest time for black for the paper used. Nevertheless, I still make test strips because the emulsions sometimes change etc. 

But in principle you are describing exactly how this system works.

Have I also understood this correctly?

Thanks for this Andrew. I’ll confess to mocking up my images in Lightroom to see how prints might look. It’s very imperfect but can be quite helpful. The print results always look more convincing however good I get at LR.
