Here's a gallery featuring artists who use Adobe Illustrator to create super-realistic drawings that look like photographs. The [a href="vny!://static.flickr.com/75/201539687_cdb0332495_b.jpg[/img]drawing[/a] of the woman shown here was created by Thai artist Ussa Methawiitayakul. Here's a [a href="vny!://www.deviantart.com/deviation/26905706/"]link[/a] showing some in-progress screen shots. I'll be damned if I can tell them from photos.
