Cool!! Keep going! I'm definitely interested in double runs and will purchase your book&DVD once it's available. I understand that while you can make the emulsion a little more monodisperse by dumping all the silver nitrate as quick as possible, still you can't control the shape of the crystal without measuring vAg and running silver and salt simultaneously at correct rate, and, the most difficult point here is the electrode and meter design.

We are going to make our second SRAD emulsion soon, now with erythrosine and decent sulfur sensitization as well as proper subbing of acetate. I've been spending my days during past weeks reading this forum. There's so much information hidden here. Thank you to everyone who has been contributing here. This is so interesting...
