Are you seriously accusing K&B of doctoring photos?
Enhanced, not "doctored". As in lighten, darken, brighten, sharpen. So you can see details better. NOT change reality.
And what CP was saying was that if this photo were "enhanced" you might see better if there were a necklace there. But this is such a poor photo to begin with, and the area of interest on it is so small, and the enlarged photo is so grainy, that any more enlarging would just pixilate and degrade.
K&B is doing all it can to counteract LE and the media (and us), but, unfortunately, like this photo, they are having a difficult time and we, at least, are not buying it.
