Daytime gave me a good opportunity to try out my brand new Schuler UV filter. Obviously the original
was very deeply colored with strange bluish tint because the filter ONLY passes light that is completely out
of the web cams passband. So it represents it with a peculiar shade. Here, converted to black and white for
clarity, some dim shadings, especially on the bottom can be seen and a very bright rim. I have more work to
do with this filter for sure, but its a beginning.
