You missunderstand what I am saying. If you have two copies of the same photo then photoshop one of those photos then it is no longer the same photo as the origional. The crime scene "photo" then becomes a forgery.
No!!!!

You are misunderstanding, although I can't see how you don't get it. Even Lookout gets it.

Which leads me to believe you are not being genuine.
Both images are from the same original photograph at some point, in the same way as if I took a monochrome photocopy of it, it would still come from the same photograph.
One copy is a lower resolution, because Mike took a photograph of a printed photograph. So the resolution of the image is reduced, however it is still sufficient to see that the blood in Sheilas mouth is dry and clotting, and blood which has flowed from her mouth is dry and cracked.
Another copy has been taken directly from the negatives by the defence team whilst GDS was involved, it has then been cropped to cut out the obviously dry blood. It has then been edited to increase the warmth, vibrancy and saturation, which makes the reds appear brighter as if it is fresher blood.
It is not difficult to understand and it is undeniable that this is the case.
If you want to pretend to be stupid and argue that black is white, then that's up to you.
