This photo ca. 1968 has been touted as "proof" that Paul McCartney was still alive in 1968. Others have claimed it shows three Paul McCartneys.
The most obvious problematic sections of the photo have been enlarged.
Left - There is a grid-like pixelation pattern throughout most of the background. It is almost like a web on top of the picture. See how the pixelation is on the right side of the blow-up, but not on the left side? A low-dpi (dots per inch) scan can make an image appear pixelated, but it would still be a consistent pattern throughout the image. However, the original image that was posted was 600 dpi - a very high resolution (twice what is necessary for print).
Middle - Notice how there is no pixelation whatsoever in this section? It is stark white. Absolutely no "netting" pixelation to be seen. As stated, the pixelation should be consistent throughout. The inconsistent pixelation is a tip-off that the photo was hacked together from different images.
Right - This person's head does not appear to be behind the mast, but rather cut off (or covered up) by the mast.
This "photo" appears to be a composite of several different images. It fails as "proof" that Paul was still around in 1968. It is not clear whether that is actually Paul's picture. Even if it is, it could easily have been pasted in.
If anyone notices any more problems with the photo, please post a comment.
