*"highly flattened pyramidal plate crystals similar to those invoked for elliptical halos*", so ascribing that former picture for a camera is a not bad hypothesis. But also, the sun occupies 1/2 degree on the sky, so, it should be around 1%... although the sun is sky is too bright in comparison to those pictures in that website.
