Yep I remember that forum... never went there, didn't think I was smart enough LOL
maybe it really is just an artifact of the image.
Unfortunately I am not a photo guy so can't help much there.
My ex g/f was actually a (dont laugh lol) "UFOologist" or whatever they call them... we tried filming to get the "rods" but failed
Never owned a digital camera so have never tried that one though!
www.mufon.org see if there is any info there...
