I believe premature peeling, then exposure of the negative to strong light (flash, light bulb, bright sun) does it.

Thanx for diving in,
I was aware of the exposure to light during process but was wondering if anybody had more precise work flows that gave them some degree of control in the process.
Going to use a hand flash, but what is a good starting value for the light? (How big a GN, how far away) and at what stage of development should i peel apart and flash.
Of course I know that it will be an experimental process initially but concern is to save as much polamaterial as possible (considering the cost)
