While shooting an obviously anorexic model, I pulled out my 6x7 and shot a couple shots on my expired 70mm film, this one, a double exposure done purposefully (though hand held so instead of her looking two different ways but the scene keeping the same, I got everything a little shaky).
EDIT: Because no one understands me... I want to explain that this is not the image I would choose to use in a printed version of my work, because this is the internet, I don't want someone saving and reposing on a public forum the clear image where you can see both the nudity and the thin nature of my subject. To protect her, I chose this image to show to you. You'll just have to imagine what a clear image might look like.
