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...

Today I made a small experiment with my vintage TAXOTA enlarger from the '60. I took off the lamp and replaced it with a can as light channel and a simple LED flash lite. Many people are trying to expose normal cyanotypes with an enlarger and a common 35mm negative, but often the UV source is too weak and the loss of light in the enlarger results in many many hours of exposure time. The standard formula is too slow for such a process. My new "Cyanotypia Cita" is basically designed for Iron...

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.

I'm actually still improving the "Cita" formula to reach a shorter exposure time. But even now it's possible to shoot an incamera iron process photography in more or less 60 minutes, depending on the aperture you choose. In my small Mouse Trap Cameras with f-stops around 1.4 and 2 it only takes 5 minutes to take a photograph In this experiment I used my old LÖBER field camera from 1895 which is equipped with a self made objective and the lens from a 110 years old binocular. Focal length is...

Interesting short video which demonstrates the exposure speed of my new formula "Cyanotypia Cita".
