Here's a first enhancement of the original photo playing with lightning curves, filters and noise reducing tools, trying to make appears the UFO like
if it was in daylight:
I wasn't able to discern any triangular shape (with different contrast and/or luminosity than inside the three lights), meaning that either there's
none or the UFO must have been at a high altitude for its pattern to be diluted in ambient haze (and then have a bigger size...)
More to come.
BTW, could it be possible for you to provide me with an other original photography from the same camera,?
No matter what the subject is, this is for some noise reducing tries.
Thanks!
