Forgivness
When I started shooting film, I was very very careful about my exposure. I was paranoid about getting it wrong.
Then I saw an exhibit on dark rooms around the world, and it included a number of photos of darkrooms from developing nations and third world nations.
Many of these weren't just converted bathrooms, but converted living rooms and bed rooms. Everything was dirty and stained. The water was brown. And yet, even in these conditions that are so far from the dust-free ultra clean darkrooms we are told are required, people are developing film and making great prints. It made me realize that in comparison to these conditions, I do have an ultra clean dark room with perfect water supply.
Are they spotless gallery quality prints? Maybe not, but no one ever said that was the only goal of print making.
After that I relaxed a bit about my own darkroom, and I started being a bit more relaxed about the entire process. What I've learned is that film is incredibly forgiving in so many aspects. Errors at one point can be corrected for later (exposure and dev temperature in particular caused me the most angst, and yet only need to be "close" to get usable results), or embraced and exagerated when that works.
It's been very freeing and I look at 35mm photography as my garage band / punk photography. It doesn't need to be polished, it can be off the cuff and irrelevant. and it is often more interesting (to me) for that.
