Good Morning Mr Reader, Thankyou for your imput, from which it appears that you have capabilities in technical matters. Is that from experience of working in a Police Socko capacity?
It surely is interesting to read that different cameras (and varying photographic film?) produce different colour reproduction, as per your, and Lookout's comments about the shade of socks.
What is to the point, to my mind, can you identify that the strange 'bluey' objects near the red bin may be the bed socks which are later shown upstairs near Sheila's body depicted on the floor of the Master bedroom?
One further point whilst I am addressing your forgoing post :- the picture which is the subject of this Topic, and otherwise referred to as 'the enigmatic picture', - from the white border to that picture, and it's accepted inferior quality, could it be a copy from a print made by means of a Kodak Instammatic camera with inbuilt flash facilities?
