Hi Sandy,

I checked back through my notes and found that it was Platinum & Palladium
in a 1:5 ratio with Na2 as the contrast agent. The long exposure scale I
believe is due to using very high humidity. That's all I know! Honest!
Please Don't Shine Those UV Lights In My Face! I'll Confess! hehehehehe
