Hi Patrick , Further to my last mail, I thought it only fair to test the theory in practice. Just pushed the 54 back to 1250 ASA by shifting the curve (Then pushed it further to 3200 ASA just for a laugh). Does exactly what I thought it would do. Some noise , limited dynamic range, but thoroughly usable image within the context. Performing arts , here I come ! :-) . Regards, Bob Marchant. Regards , Bob Marchant.
