We managed to put the multicontrast back into our Polywarmton resurrection emulsion.
In the above image you can see the original vs. the new emulsion coated with a 50 micron layer.
The left hand scale is always the hard and the right hand scale is the soft grade.
This was attempt number one. We will keep matching the two now until perfection and alternatively play a round a bit to see if we can actually do better than the original.
