RE: Digital neg

Hi Maria,
First is that your print will be the same size of your negative.
By this meaning that if your negative is a 35 mm B&W (and you don't want
that small size) you need to print a positive B&W on a translucent paper of
the same size of your final print. With this positive then you produce a
negative that you will be using to produce your gum print.
The following steps are basically the same as we have been discussing for
digital negatives gum printing which is to prepare your potassium dichromate
sensitive emulsion to mix with your gum and black pigment.
The dichormate concentration varies according to your UV source (solar or
lamp type).
Obviously if you are in Sweden your solar UV is not the same if you are in
the tropics.
You should find plenty of information allover.
