the people/trolls on the discuss list can't see your attachments, but i 
looked at them and they are easier to see but maybe more blurry?  I don't 
know.

I was told to take pictures in a different format next time, maybe RAW 
format.  Also i think x-rays were hitting the camera despite the glass 
screen in put in there.

it was a 15 second exposure.
