Benjamin,


There may be some interesting reading here: http://strobist.blogspot.com/search?q=long+exposure+portrait


Other than multiple exposure thebest way to get a long exposure portrait is to expose the ambient and strobe the subject. The subject must be kept completely in the dark for this to work very effectively. I tried taking some long (4-6 sec) exposues of my youngest son while he was sleeping because I liked the way he was positioned and the ambient light that was on him. He did not move during the exposure. However, he was breathing. Just from him breathing the letters and patterns on his shirt were blurred.


Oh, one other. There was a detective TV show on a few years back where a photographer was so obsessed with sharpness that he payeda guy to bring in a model to photograph that was dead! I wouldn't suggest this method.


I'm sure if you researched long enough you can find some techniques to accomplish what your trying to do.

Of course Photoshop was an essential tool.


Good Luck,
