Hi Peter,
               This is interesting because I had forwarded the picture to 
Earle Williams with no comments and he wrote back it was possibly a fake 
and what did I thing and why.
So I zoomed in and made him a report of various items as I studied the 
picture. He's heading out of country and has not made reply yet with my 
"grades". I did note the main channel area in zoom had a wider bright area, 
like afterglow but it did conform with the channel path to the top of the 
lower clouds. I got the impression it was a positive cloud to ground and 
dividing also to a cloud above it. Don't know if that wide bright area 
either side of the main channel was camera saturation or not. The area 
toward the camera, darker ground, does not show shadows of light from the 
stroke direction but the trees closer to the direction of the strike seem 
to be lighted more or less as expected.
Mike
