They were ENHANCED.
I rarely use the word "photoshoped" because it's been used incorrectly to describe a lot of different effects and you certainly wouldn't have to use Photoshop to ENHANCE a video screencap. Most software that extracts them has the tools available and even uses them automatically. So you could ENHANCE an image without knowing it's being ENHANCED. And as you can't see the difference between the two previous examples, the only way you'd ever know is if it was written on them.
LOL I've heard it all now...

you know you were caught, so rather than admit you were WRONG you are now claiming that the possibility that Bizzy posted enhaned images without knowing they were enhanced..
LOL
why don't you be a man and admit you were wrong?

and as far as the differences go, of course we can all see the colour differences.
but all three sets of screencaps were slightly different colours, as are some of the videos on youtube.
I suppose ALL these must be 'enhanced' too?

Because that is what you are suggesting.
you are up against the same wall ND is, and you can't get out of it...
