Hello, My name is Peter. I am a newcomer and beginner trying to make a Chloro-Bromide projection paper emulsion using a recipe from Denise Ross' wonderful book 'The Light Farm'.
I am substituting the gleatine with PVOH, sometimes also mixing in PVA.
My watercolour paper is subbed with PVA, but still my emulsion wants to dissolve in processing (even if I leave out the stop).
Where I have got an image, the finished product is 'Slow, fragile and has a short life' just as Ilford said it would be.
I've tried adding talc, cornflour, agar agar at various stages.
Any leads would be gratefully appreciated!
Thank you in advance.
