Fogbow Polarisation Comparison

This pair of panoramas taken a few minutes apart shows the effect of using a polariser. For the lower image a polarising filter was used, it was rotated to fit the bow for each exposure.

In this view, without filter, the full arc of the fogbow is visible. However it is a bit thin at the top because the fog was only just deep enough. This image doesn't show the bow quite as well as it appeared to the eye.

Full fogbow with polariser

The polarised view shows two supernumeraries over most of the arc, although only one was obvious to the eye. That was sufficiently strong to show a hint of colour, but not as strongly as shown here.
