Warning … Image #6 is about as bad as it gets! It shows a nearby bright star ruining the field with this setup. Shiny structures at the chip’s edge cause specular reflections so complex that I have not found a good remedy for this case of scattered light. Sometimes rotating the camera and changing its orientation can help mitigate the reflections, but it isn’t always possible.
And with that I leave you somewhat on a low note by presenting you with an image that would take more time to repair than to create in the first place! However, my next column will look at another interesting example, and I will demonstrate a technique that fixes it as well as other similar problems.
