Well it is definitely 'on' the photograph.
That part of the 'ufo' is 100 percent on the photograph and isn't altered by the processing that I mentioned.
I simply 'enhanced ' that area and those darker / antenna / pixels are on the photo in that spot and not anywhere else surrounding it to that amount that is.
When you work with ' pixels ' and small details like this all of the time it is real.
If ( silly I know ) I was restoring this photograph that 'antenna' wire / hair would most assuredly be in it.
Anyway that's my input to help out.
i'm not saying its real life hair. i mean the pixels seem to be forming a hair shape vs the regular jagged pixel edge im used to seeing in enlarged photos.
