LOL! Jorge I have not been mixing Pt & Pd because I have NEVER been in possession of a single drop of the Pt coating mixture. The entire comedy has been an exercise in Ultra High Contrast Palladium printing.
Also, a demonstration of how one will bend their perceptions of reality to conform to an existing belief... I thought I was printing with platinum so... extreme exposure times, must be the latitude.... no midtones must be the developer or the humidity or the paper or static in the coating rod.... I even went as far as to develop my own method of coating FB silver paper and getting a friend to build me a new contact printing frame in case the one I had was holding some kind of vaporous grudge!! I have been spinning like a dervish for hours in the darkroom trying to bring my negatives into line... which isn't easy when the 'curve' is in fact dead straight vertical but you still need zingy negs!!
Another interesting thing to contemplate.... What was 'really' happening in that toning test I tried a few days ago...the Pt in my 'formula' was in fact NA2... Might explain why that baby jumped a paper grade instantly and oh...those crazy extended midtones... (secretly I think NA2 might have potential with silver based papers in modifying the curve).
So there you have it... the Photo gods have had a wonderful laugh at my expense.... (literally.... those supplies aren't cheap!)
