Oh, I dunno....

I'll admit I didn't know EXACTLY what they did either for few months after re-starting darkroom work. That was a couple years ago. When I was doing it for the first time decades ago, I really didn't know - or cared. Dev, Stop, Fix, WASH! was all I knew.

As I went fully into this "thing", I studied and learned what happens.

Maybe we all forget how we all started...
