My first post after a stint on another board that seems caught up in digital "I only change the same things just like you do in the darkroom" - yea, right.
I'm strickly anti-digital, so I thought I might be more at home here
On these color cards, help me out - never used them although I have a darkroom with twin D5XL enlargers and a 31" Kreonite processor on color.
Are you adding these color patches in one of your photographs and then adjusing your enlarger color Pack so the colors match? Just wondering if I need to get these?
