I was going through some photos of a test pavement construction I did 18 months ago and noticed something quite strange in the top left hand corner of the photo. Can anyone begin to explain what that white light is that appears to have a small trail leading from the vacuum cleaner? click here for the photo I assure you that all I did was open the photo in Paint, scale 30% of the original in the x and y directions and save it. There has been no editing performed whatsoever. I have the original photo downloaded directly from the camera click here to see the other photo. Another photo from a different angle with the vacuum cleaner in it comes up clear. The photo was taken in a shed. It has freaked me out a little. Any ideas?
