I keep saying I will stop and I keep not stopping. Two stops turns an overcast afternoon into something with weight. The grain is the point, not a side effect. Developed in DD-X at twenty degrees, agitation every minute for the first three and then once a minute.
Thirty-six frames of nothing. The take-up spool never caught, which is a mistake you make exactly once with a camera and then never again, because now you watch the rewind knob turn on every single advance for the rest of your life.
Negative film forgives overexposure and punishes the opposite. If the shadows have nothing in them, no amount of scanning brings them back. Highlights, on the other hand, will sit there patiently holding detail you did not know you recorded.
