Projection in photography was once used a lot. Much like back projection in films it was used to provide a variety of backdrops. It is rarely used these days because backgrounds can be replaced so easily in post processing.
I have used a digital projector to project directly onto Michelle's body.
I load a laptop with a whole range of images then cycle through the images, exploring the effects of each in turn. Geometrical shapes (as seen here) work very well. More abstract or fragmented patterns tend to be less successful and more trial and error is involved.
This could so easily have been presented as a monochrome image, but the little flash of red hair serves to highlight the white areas as being truly white - not just bright skin tones.
The way the straight lines wrap around the body give a wonderful sense of shape and form.
You will need to spend some time getting the height and distance from the projector to the subject correct. Most modern digital projectors are built to give a large image at quite a short distance (for use in meeting rooms).
Because the projector to model distance is short, the focus range is quite narrow. Your model cannot move to far forward or backward without the projected image falling out of focus.
Your camera needs to be at quite a high ISO, since although quite bright projectors are still not putting out a lot of power and that illumination can be lost as soon as coloured images are used.
In darker conditions your auto-focus will struggle so you will need to manually focus throughout the process.
