Almost all of the iron processes are negative processes. That means you end up with a negative, and there is almost no way to get a positive from a typical cynonegative. This because the contrast of the whites and blues are way too weak for a contact copy.
But there exists a forgotten process from Louis-Alphonse Poitevin. This Ferro-Gallic Process is a positive process and is very fascinating.
I worked some time ago with this process and discovered the potencial for Iron Photography. Actually the exposure times are very long, but I'm experimenting to make them shorter. May the discoveries from my new "Cyanotipia Cita" could help me here to find a solution.
So stay tuned for more details about this forgotten process!
