- List two procedures to fHMIS (U.S.A.):
- What color was the cyanotype emulsion when it was applied to the paper? It was a yellow/green color
- What happened when it was placed outside in the sunlight? Why? The color got lighter because the chemicals reacted to the heat from the sun.
- When your print was removed from the glass and the objects were removed, what did you observe? The outline of my drawing stuck onto the paper.
- Describe what happened to the exposed areas of the print and the unexposed areas of the print when it was placed in water. Why do you think this happened? The exposed parts changed into a white outline and the unexposed parts did not change, because the water washed off the unexposed areas.
- Any final thoughts about the way it looks, feels or your observations of the process? I think that it turned out pretty well. I noticed that my drawing did not really appear on the paper.
