I have never developed film, but I granddad had a darkroom in his wood-working shed. He even had a color enlarger, which was very rare at that time. I would have liked to have learned, but I only started getting into photography when I was 18ish, years after he had passed.
I miss those days when I learned how to develop b&w film on a development pot,
I think that part of the "miss" is the methodical process. Like a meditation with checkpoints where something is actually experienced.
but we have lost the chance to learn about photography.
And learn about scarcity and cost.
