Not sure what "hyperrealism" really means, and it's not very important. Here's a list of painters who do incredibly technical stuff. If you don't like hyperrealism, at least you can learn a few tricks (a lot of them use to post and share steps).
Hubert de Lartigue
Of course, it's not an exhaustive list. If you know some interesting hyperrealist artists, don't hesitate to post a link on your comments.
