Dear Winterleia, and all other members.
My local photographer - now around 65 years old - says that he can do exactly the same with old style analogue photo's in the dark room, as photoshop allows.
It will take him far more time and effort.
After screening many prints from the films found by the first search party using:
-
https://29a.ch/photo-forensics/#forensic-magnifierI have come to the conclusion that 'I have to take into account that the prints have been composed at a later moment'
I will show the analysis of two photos (available at dyatlovpass.com )
The photo above, shows Yuri Yudin on a place outside the tour.
The magnification of the change between 'the coat, trousers, and background' is visible in the rectangle: it appears sound and sharp.
The photo above is one of the film found by the first search party.
The changes from jack and background is blurred by a gray line of 3 picksels wide; as far as I know on all photos these changes are 3-4 pics white or gray.
This surrounding of objects is user for:
- highlighting objects from the background or
- camouflaging that object have been added.
When all or nearly all objects are blurred by a grey/white line around, the suspicion arises, that the photos are mere composition from other source material.
A few Russian bloggers are far more outspoken about the value of photo for evidence to solve the case.
