"Black and White Handbook" - who has one?

phariseo · Oct 5, 2013

Hi and welcome!

I need one information from "The Black and White Handbook" (this book isn't available in Poland). I have Polish colour enlarger head (named Krokus GFA), which scale is based on Agfa colour enlarger heads.
In "Black and White Handbook" there is information about how this scale compromises with Ilford Multigrade scale. I need certainly this part .
Would anybody help me with it and take a shoot of this part of book? I'll be very grateful.

With regards from Poland,

Should be in the Ilford datasheet for contrast control. Your enlarger should be similar to the Meopta.

There isn't . Ilford hasn't accounted eastern bloc stuff in this datasheet.
AFAIK, Agfa adjustments are totally different than any other, and they're contained in this book.

I updated my previous post as the Meopta settings Ilford give are the same as the Agfa settings.

Welcome to APUG BTW

Thanks .
Unfortunately it isn't. It's most similiar to Durst (max 130M) one, because maximum value for every colour is 140. If Agfa = Meopta, maybe this Polish head isn't really similar to Agfa?
Does it make any practical difference in prints contrast? (+- 10 difference in values).

In practice it doesn't really matter, I've never referred to any charts when printing with a colour head, I just add more Magenta or yellow to increase and decrease the contrast. It's only if you want a definite grade.

Ah, now I understand! You helped me a lot .

There are at least 4 different density systems one should know when dealing with colour heads:

-) densitometric density

-) Kodak density

-) Agfa density

-) Agfa density from the 50s
