My first post here on ATS… this thread just convinced me to register.
I have an extensive photo background and would like to throw some theories your way.
First of all…
To correctly analyze a printed image you need the printed image itself to digitize it under several color filters, but above all to examine it via a
loupe.
Only with the physical image and a loupe can you expect to see the grain of the negative and thus evaluate focus and grain patterns correctly.
What we are examining here is the scanner's binary interpretation of the film grain, it is total guesswork. Any mosaic patterns and staircase pixels
to be found (like the ones 11165 is suggesting) are most likely from the scanner and from the digital camera used by the OP. No pixelation or mosaic
pattern analysis can be done to a scan or a digital photo of a film print.
Then there is the problem that the best scanners in the world are not as good as the human eye, they see white were we still see detail and same with
shadows, they black out before the eye does. It's called dynamic range and our eyes have a huge one compared to scanners and cameras. I bet there is a
lot of detail in that print to be found by a loupe that the scanner is not seeing.
About the supposed lines holding the object in place:
If such an average quality scan (no, this is not a good quality scan) showed traces of cables supporting the object then they would be very visible in
the original. So they are probably not physical lines but damage to the print.
Ok, so since this scan is all we have let's have some fun with it…
Sky seems with a white overcast and the light on the trees appear to confirm it, there must have been a thin cloud cover all over the sky that day. No
specular highlights from the sun either, again supporting the overcast theory.
First thing I did was check the focus, edge analysis gave me 6 planes of focus in the photograph:
1. Trees on the right
2. Object
3. Tress on the front
4. Trees on the left
5. Slopping tree line coming down from the left
6. Far hill top
The first level are the trees on the right (#1) with the thickest most defined focus edge and the last level is the hill top on the back with a very
thin focus edge (#5).
Edge tells me that: the camera was focused on or near the trees to the right and the object was most probably behind or in front those trees.
If the object was in front of trees #1 it would be very close to the camera and very small, smaller a hubcap I think.
If the object was behind trees #1 then it was not that small (at least a car in length) and it would appear to be closer to trees #3 than to trees
#1.
Haze and discoloration…
I sampled a lot of areas in the picture and I'm not getting the same values of density that jritzmann appears to be finding.

Now when you sample the darkest area(s) of that tree, you see the value. Now sample the darkest part of the object. The object will show darker black
levels than the tree. That means, it's closer than the closest object in the picture. Meaning, it's small and relatively close.
The object shows an average black density of 228, the trees below the object have an average black of 230 (very close) but the trees to the right show
an average of 239.
So actually, black density is telling me that the object was farther away than the trees #1 and around the same distance as trees #3
Color…
This is not a black and white print as some have suggested, it's color but the years have washed most of it away.
The scanner is picking up 2 distinct color casts on the image, one for the sky area and another for the trees.
Here we find something interesting, the object is registering the same color characteristics as the surrounding area, the sky color in the top and the
trees' color in the bottom area.
This supports the idea that the object was physical there, in that environment and also it would mean that it was probably a grey colored metal (like
aluminum) without any color to it.
As for the uneven ridge…
This is the only thing that stood out to me, why a broken edge like that on the side of the ship?
The only theory I have is that the object is shiny metal and we are seeing the reflection of the trees in front and below of it.
It's as if you parked a silver car to the side of the road, you would see the trees and mountains reflected in the car's side darker than the
reflection of the sky. The outline of the tree tops against the sky would be very evident on the side of the car.
Although this tree line reflection theory is quite a long shot it's still feasible and I'm just trying to cover all possibilities.
My theory so far…
It's a physical object of unknown size that's located farther than trees #1 and close to trees #3
Unfortunately without the original a thorough analysis is impossible.
