Dianne Bos (http://www.diannebos.com/sound/sound.html) has done some work combining both audio and the visual. For the show that I saw, she made pinhole images while recording the sounds that occurred while making the image. The show was the combination of both types of media, making it quite interesting.
That is interesting. Our local newspaper photographers have done something (vaguely) similar; they've fought for their own website, and now regularly post slideshows with sound.
