One shot developers do what they say on the box! They are for single use and have a quality advantage over reusable ones, also removing the worries about usability. I know this may sound wasteful in these times of rising prices, but what cost do you apply for peace of mind when developing those precious negatives.
- Fresh developer each time.
- Ensures constant quality.
- Consistant developing times.
- No need to use replenisher.
In most cases these days most developers can be used as single shot, in the case of PMK Pyro and RO9 it is the only way.
