This isn't one of the newest things to hit photography, but is still incredibly interesting and innovative. The Scanner Photography project is a photography process using a flat bed scanner instead of a digital image sensor or film, the scanner is strapped onto a large format camera body to create a contraption capable of taking over 150 mega pixel images depending on the maximum resolution of the scanner used,even cheap scanners can scan up to 2400dpi which creates a huge image
because of the way scanners work, there is no discrete exposure time. The sensor move across gathering light instead of exposing the whole image sensor at once, this adds a completely new element to picture taking that is individual to this type of camera.
Mike Golembewski is a leader in this type of photography and has a very interesting website which sadly it would appear has not been updated in quite some time, but if you look on flickr there is quite a lot of experimentation still going on with this.
