The real thing: Angelina Jolie on the red carpet

Johnny Depp, Nicole Kidman and Michael Jackson also appear in the pictures which have been produced by amateur artists using Photoshop.
The remarkable images were all designed to be passable as an 'original' to the untrained eye.
Each one took the amateur artists anything from a couple of minutes to three hours to complete - and were all produced on digital software.
Amira Wruble, site manager of Worth1000.com who displayed the images, said: 'They use all sorts of techniques to bring the images together to make the the final product look as real as possible.
'Most of the users aren't artists by profession, but still have great skill to produce these fabulous works of art.
'It takes me two or three hours to craft a really outstanding photo, but some people can do it in minutes.'
The images have been digitally aged so that they appear genuine and untouched.
Amira said: 'If you see anything on the net that looks too crazy to be true then you're simply seeing the work of the visual tricksters who play at Worth1000, which is a kind of playground for artists and graphic provocateurs.
'We run loads of competitions to allow our users to turn their hand to all sorts of humorous manipulation.'
