Hello PE,
I am still a bit confused about what appears to me to be a contradiction between your original recommendation of 200mg SDA3057 per mole of Ag and a latter statement that the dye should be used at 60 mg per mole of Ag. Because of J aggregations, the dye needs to be double coated over the particles of silver halide. Without the j aggregation, SDA3057 is just another green sensitive dye.
