One of my pinhole camera's were installed in Neerglabbeek (B) with view on an open eastern horizon. Part of the south and the entire western horizon was blocked. The solargraph is perfectly captured and very clear.
Another solargraph was installed in front of a tower in Zichem. Unfortunately is pinhole camera was damaged as it was installed in a public area. So the photopaper was flattened and ironed and again scanned and edited using CS4. The result is shown below and quit good. The tower is seen in the front.
