Reading a negative on a light table
· From the bench at Silver & Grain
What a dense negative is actually telling you, and why the fix usually lives in the print, not the tank.
The light table does not lie
Hold a negative up to the light table and it tells you three things: where the light was, what the film did about it, and what the print will have to fix. Learning to read those three things apart is most of darkroom craft.
A dense negative is not a bad negative. It is usually an overexposed one, which is the easier problem: shadow detail is on the film, and the print just has to hold the highlights back. A thin negative is the harder one. The information was never recorded, and no amount of printing puts it back.
Density is information, not failure
The mistake most new printers make is treating density like a grade. A negative with thick highlights can print beautifully with a half stop of burn on the sky. A negative that looks bright and airy on the table often prints flat and dull, because the contrast was never there to begin with.
Read the negative for what is on it, not for what you wish you had shot.
The fix usually lives in the print
When a frame looks wrong on the table, the instinct is to blame development. More often the negative is fine and the print plan is missing: dodge the shadows four seconds, burn the window a stop and a half, and the frame that looked hopeless makes the best print on the sheet.
So before re-shooting a scene or re-running a tank, print the frame. The test print is cheaper than the assumption.
