I have my own private theory on lens flare and have never seen it expressed 
anywhere before. Anyway, lens designers create lens for the contrast range 
found in common scenes and exposed onto common films, black and white or 
color. Many times, the contrast of a scene will exceed that "normal contrast 
range" and what will happen is flare just like seen in #34 above. Your scene 
may well have had a 12 to 15 stop range of exposure values and was way beyond 
the design capabilities of your lens.
