Number 8 the "chicken" is interesting because it catches a two tone colored border with what looks like lettering or numbering on the blue rod. Certainly nothing in the photo bears any relationship to the tent. I would speculate that this photo was an attempt to film something on the other side of a glass window taken from within a building or a moving vehicle. Of course, it was a failure and the "chicken" is just an artifact of no real significance. What seems important is whether this is the only color photo in the entire DPI archive? Suspicious, yes? Could a linguist hazard a guess as to the meaning of the obscured lettering?
I do not recall anybody suggesting these granular and streaked magnified images coming from the middle or the ends of a roll of film.
In this strange, years-old mystery which has been examined by so many experts and lay-people for over 60 years, I think all theories should be properly considered, even Yeti.
I am intrigued by Henning Kuersten's book, but this will be the last time I quote it, as I'm not trying to push it on anyone. If your (or anyone else's) interest is piqued, they can buy it themselves and read his theory.

..... I became convinced that the Dyatlov group perished in the wake of a rare but massive electromagnetic plasma event, commonly known as Earth Lights, Aerial Plasmoids, or Unidentified Aerial Phenomena (UAP), and most often mistaken for Ball Lightning. Due to the variability of the phenomenon and the dispute about the correct denomination, I will introduce the term Aerial Plasma Phenomenon (APP) and present a more detailed classification in the "Believe in Science" chapter.
.... I will also demonstrate to you that SX and K34 are not technical shots, but pretty good night-time photographs of this same spectacular phenomenon, which has seen repeating occurrences in the Ural mountains up until today. The following image is a histogram-equalized collage of our three "Famous Last Frames," to which I will later add more from this second hotspot in the Ural mountains. We will also learn of other similar spectacular incidents, adn slowly but surely paint a precise picture of what happened on that extraordinary but tragic night on the Dyatlov pass.
In the end, a lot can be interpreted into blurry, scratched, and weathered images. But Z7 is in my opinion the most intriguing evidence, something a criminal investigation might call a smoking gun.
