För den intresserade finns det en ganska fullödig analys av fotografiet utförd av en viss "Andrew Robinson Senior Lecturer in Photography, Sheffield Hallam University, Sheffield."

SUMMARY
After detailed analysis of the image itself and the physical properties of the print it is my considered opinion that:
• The photograph is a colour print from XP-1 chromogenic Black and White C41 film printed on standard Kodakcolour negative paper of the early late 1980s or early 1990s.
• The choice of XP-1 film should be noted as it would suggest someone with a knowledge of, and an interest in photography.
• It is likely that the image was taken on a SLR with a 50mm, 80mm or 110mm prime lens or a mid-range zoom lens OR on a compact ‘point and shoot’ camera with a 35-70mm or similar zoom lens.
• The image shows no evidence of negative or print based manipulation and all visible signs suggest this is agenuine photograph of the scene before the camera.
• Relative measurements of objects of known size within the photograph allow a calculation of an estimate of the approximate size of the unidentified object of between 30m and 40m with a height of between 8m and 12m.
• The overcast sky visible in the photograph is consistent with that recorded by the UK Met Office for the given location on the day the photograph is claimed to have been taken.
• It is not possible to identify the object in the centre of the frame however the evidence present suggests that this object WAS in front of the camera in the position shown when the photograph was captured.
• It follows that this is either a genuine unidentified flying object in the sky OR that any construction or manipulation used to create this effect occurred IN FRONT of the camera and NOT in the capturing of the scene on film nor in the subsequent processing and printing of the image.
• The results of this analysis are consistent with, and support the claimed heritage of the print.
