It’s all about light

Audrey Penven’s use of Microsoft Kinect’s infrared structured light to create these photographs reminds me a lot of Dentsu London and BERG’s work on creating Penki, the iPhone app that allows you to paint 3D messages and images that are revealed in long exposure photographs.

I think there’s a lot to be said for structured light, or as Wikipedia says “the process of projecting a known pattern of pixels (often grids or horizontal bars) on to a scene.” They further go on to say: “The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene.” It doesn’t seem all that cool at first if you’re not familiar with the concept – takes  a while getting your head around it, but Audrey’s description of the process of the shoot is fascinating and helps understand what it’s like:

For this shoot my models and I were essentially working blind, with the results visible only after each image was captured. Together, we explored the unique physicality of structured light, finding our way in the darkness by touch and intuition.

Working blind!

BERG were also able to create the original light-painting video by using iPads to “create three-dimensional images out of light, using long-exposure photography and stop-motion animation”.

As Tim Carmody says in the Wired article, I feel we’re going to be seeing a fair bit of products and processes that use light – and structured light – in the future. Stay tuned.
