pre-soak ?????

I have a jobo drum expert and would like to know how to do the pre-soak, rotating the drum is necessary? with how much water? thanks Stefano

Fill the drum with as much water as you would for the chemicals, then rotate the drum for a couple of minutes.

Some presoak for two minutes, some for five. They both work, but will give different results. Whatever you chose stick with it.

for presoak, developer, and stop, i fill the drum while it's spinning. a funnel with a short piece of flexible hose on the end does the job, and costs a bit less than a jobo processor (many thanks to jobo for the idea, by the way).
