Do you object to using variable contrast paper and filters? Do you object to using graded papers? Do you object to using different manufacturers' papers which while marked No. 2 differ somewhat in their contrast? Do you object to using a diffusion head in lieu of a condenser head? Do you object to using different developers? Do you object to flashing? Do you object using masks? The list goes on and on. Can you clarify exactly where you draw the line before you have to commit the mortal sin of scanning your negatives?
Though directed at cliveh, I think about these things too.
If the original is a transparency (e.g., Panatomic-X developed in a reversal kit), or color neg/slide. Then I am not interested at this time in printing in the darkroom. If brush and scribe retouching is impossible due to horrendous processing (air bells or low levels). I have a few rolls of those but I switched to steel tanks and agitate fiercely now. Steel tanks vs. Paterson probably made the most difference. For those I am sorry brother faberryman, I have sinned.
Negatives in the darkroom go through rigid steps to print. I eschew all light sources but the Aristo grid with Zone VI stabilizer keeping light level consistent. I truly believe Horowitz and Picker came through on that gizmo. Gelatin ND 0.60 filter is a consistent drop-in right on top of the enlarging lens. I know it’s poor form but I do it anyway.
All my normal negatives will print on Grade 2 or 3 Galerie with about 1/3 stop burn or dodge. I feel as if I haven’t given a print the proper treatment unless I burn or dodge something. My outliers will print on Ilford MG IV with under lens (I think they are Beseler brand acetate) polycontrast (or Wratten gelatin blue or green) filters.
Every print gets a test strip, only rarely will I print two adjacent negatives without checking. I almost always get burned by having a dud print when I do this.
And the enlarger height is locked per format according to a note pasted on the enlarger carriage. Most of my carriers are filed.
I have gotten into this heated discussion before and brashly demonstrated how someone else’s negative could be cropped. The guy must not have liked my idea because I haven’t seen or heard of him since.
So I demonstrated on one of my own negatives…
This is what I came up with in the darkroom with cropping. Two different prints from different parts of one negative. Not previsualized at the camera, although at the camera I tried to make sure the negative would be a good one, it was skewed so not suited to my usual standard treatment.
