Finally summer arrived and the weather is warm and wonderful. Perfect conditions to make some new experiments with my new formula "Cyanotypia Cita". After the last experiments during winter I'm able now to have only one solution for the sentisizer. Ant it seems to be very stable during many months of storage. The sensitivity is still very good. The paper reacts in the sun within seconds. But that makes it also sometimes difficult to handle outdoor. A half second of sunlight and the paper is...

Today the weather finally became better and sunny again. Time to test the new lens and f-stop configuration of my big camera "Soul Catcher". I coated a sheet of Hahnemühle Platinum Rag with the new Cyanotypia Cita formula and exposed it during 60 minutes with the new f-stop of 5.6. Before I used the camera with f3 and the deep of field was too small to get nice results. Now with 5.6 it's a lot better, and the exposing time didn't raise much. The result is great! Now I'm ready to shoot large...

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...

In this short video I show the sensitivity of the new "Cyanotypia Cita" process. This formula even works with a common LED flash light. To expose iron prints by using a normal light source opens completely new approaches for teachers and classes, because UV light sources are not always everywhere available. The other huge advantage is the simplicity of the chemistry. "Cyanotypia Cita" is harmless, easy to use and has a good stability for storage.
