Thank you denise,
I am attempting to use relatively cheap dyes for my emulsions. Sands dyes work well. But $600/g + Convenience fees is just too much.
I have tried adding erythrosine as a finishing component and have newver seen an increase in greensensitivety. I shall atempt it again with your method. But my best emulsions are weird enough to produce totaly different results. 'Cors , I can always return to extracting dye from dead red beetles -
