This emulsion, when sensitized properly and with other addenda and treatment is similar to the Ortho 40 speed emulsion that I posted elsewhere.

It is very sharp and very grainy. I have another ISO 3 - 6 emulsion that is only blue senstitive, but is much less grainy. I have yet to do much testing to see what kind of overall results can be obtained, particulary if I try to maximize the speed.
