The One and Only Billy Shears2014

Sam:
So first it goes into the developer. Usually it stays in here for about two minutes, but you can leave it in longer if you want to.

Billy Shears:
What happens if it stays in longer?

Sam:
Well, the longer it stays in, the more exposed the image will be. It's like shedding layers: more exposure time means more layers shed. So then we go into the water to wash off the developer. Not for too long, though. Then it finishes up in the fixer.

Billy Shears:
What does that do?

Sam:
Basically it makes everything permanent. The fixer washes off what's undeveloped so all that's left is what's exposed. After it's fixed, after everything's settled and realized, it can't change anymore. And that's what we want: one fixed image.

Billy Shears:
And then you edit it?

Sam:
It's got to dry first, but you can. I'll show you.
