IR “Paintings” Visible Only Through Your Digital Camera

This project is called Take A Picture, by Toronto artists Brad Blucher and Kyle Clements. Though described as “paintings,” it appears that their pieces are in fact IR LED mosaics assembled behind blank canvases. Invisible to the unaided human eye, the IR light is detectable by the CCD in your digital camera and/or smart phone. [via Hack a Day]

  1. it must have been a pain to get the photo of the effect from a digital camera! ;) Good project, I’m very tempted to follow your instructions.

  2. “it must have been a pain to get the photo of the effect from a digital camera!”

    The promo picture was shopped. (well, “Gimped”, but that just doesn’t sound as good)

    I Shot the canvas when it was unplugged, and the cell phone when it was plugged in, then composited the two images together.

    New DSLRs like the 7D and D7000 have really good IR filters built into them that block out IR really well, so it would be possible to re-shoot this image today without any trickery. But I’d rather spend that time building new stuff.

  3. I’ve been wondering where I can find potential dyes that are either dark-appearing but reflective in the near-IR, or light in color (within the visible spectrum) but absorbent of near-IR light so as to get an effect like this, but without the need for LEDs.

    1. We had the exact same problem with the iphone4. It simply does not see the IR. Nor do new DSLRs. It’s a shame, there is a ton of potential in this, and camera makers are taking it away by making better cameras.
