An image printed on reflectance paper responds to the direction from which it is illuminated. The reflectance paper is covered with dimples that reflect light from different directions. See video ...

All things considered, modern photography is pretty easy. It’s really just a matter of pointing the camera at the thing you want to take a picture of and letting the camera do the rest. But that doesn ...

Streetlights keep us safe at night but also contribute to global carbon emissions. Lighting accounts for 20% of the world's electricity consumption and nearly 6% of greenhouse gas emissions. Now, ...

It was a dark and stormy night. (I've always wanted to start off with that line.) You were driving home from work. The rain had finally stopped, but the roads were wet and shiny, making it difficult ...

Researchers at Intel Labs in the US have developed a 3D display technology that can correctly model the way that objects reflect light and that fits into relatively small hardware accelerators.

True holograms are 3-D images produced by the interference of light beams that reflect off a real, physical object and can be seen with the naked eye. There are many different types of holograms. One ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. A week or so ago, I got a question on Facebook that was relayed from ...

Scientists have created new types of 2D nanostructured surfaces which appear as realistic 3D objects – including shading and shadows – using nano-engineering techniques. When light hits an object, the ...
