Polywarmtone Project 2009 – 2019

In the past 10 years we have made thousands of emulsions.

We had to replace 50% of the ingredients and start over from scratch numerous times because of this.

To give you an impression we opened one of the many archive boxes. Each single greyscale sample here has been a change in emulsion (variation of make, blend, ripening, sensitizing, stabilizing, additions), a hand coating has been made-, exposed, developed fixed washed and dried and then analyzed measured and a curve has been plottet.

Each one of these sheets means days of labour for a highly skilled professional plus a lab technician.

This is just to give you an idea of how complex a silver halide imaging system is and why any emulsionist will roll his eyes if you ask him “can we please change a little bit in the emulsions so my film looks different?”.

Needless to say we also publish this because the above question is not unusual 😉
