Light-sensitive paint???

Question

Hi folks,

I'm looking for a paint that has the following qualities:

- Is paintable onto a wall (either spray on or roll-on is fine)
- Changes color according to the color of the light that shines on it
- Is long-lasting

An example application would be projecting an image with a computer projector onto a wall. You would then paint the wall with this magic paint, and the paint would dry once its picked up, or 'burned in' the image being projected onto it.

If anyone knows of such a paint, I would be very grateful. Or any other ideas about how to achieve the above type of project would also be welcome!!

Regards,
Warren

Well, I just found some info on a photo-sensitive paint made by Pebeo, called Soleil. It's intended to use on fabric, however.

Try doing a search for "photosensitive paint", maybe you'll have better luck with another search engine... I did see what look like some interesting leads, but pretty deep in the chemistry department if you're into that...

No, there is no such paint that your asking for... The easiest way to accomplish the task you are asking for is to use the projector to make a tracing of the picture on the wall with pencil and paint in the colors afterwards. you could use painters tape to block out the edges to achieve a cleaner edge. The only light-sensitive paint on the market today are glow in the dark types.

Though, even if it were possiable, the paint would eventually fade away. The closest thing to what your are talking about is in the lightscribe technology, which uses a lazer on a very specific frequency to "burn" designs on a CD/DVD, but when they are explosed to light they to eventually fade in time.

It's not a stand alone form of photography, but rather a technique that a creative photographer may use to their advantage. It takes advantage of using a long exposure when in a dark environment, which allows the photographer to move in front of the camera without becoming visible. To get these effects, you need to have a small LED torch on the end of a string, and learn how to project these patterns out.

Ever thought of using the photo emulsion resist method that they use in the silk screen printing process? Warhol used this to great effect with his portrait series. its actually a very simple process although the equipment is rather a bit of an expenditure. Basically you'd need to color separate the image(any good graphics house can do this for you for a nominal charge) then all you have to do is burn the screens using photo emulsion (again available at any good art store) and print them on the wall. the only problem I see is that of registration and of course size, but there's the rub. I know that in the display profession this is the way they do large images on a wall.
