Zone VI VC head question

[kjsphoto]

I am wondering how many stops are there between settings?

For example if I set the control box to say 2 1/2 and then change it to 2 what is the stop difference? Is it a stop / 1/2 stop , etc?

I am trying to make a change in filtration and wanted to know how much I have t o decrease the time fro exposure? I am moving from 2 to 1 1/2...

Thanks,

Kev

It's going to depend upon which paper you're using. You'll need to test to find out and then keep notes. Different papers will behave differently, not only in terms of speed, but also in terms of the relative contrast achieved. Just because your control box says "1 1/2" doesn't mean that any two papers exposed at that setting will result in the same contrast.
