Fine art photographer Nancy Breslin joins NPR's Scott Simon in studio to celebrate Worldwide Pinhole Photography Day.
No lens required: how to shoot stunning, dreamlike images with a DIY pinhole camera ...
Scientists have developed a lens-free mid-infrared camera using a modern twist on pinhole imaging. The system uses nonlinear crystals to convert infrared light into visible, allowing standard sensors ...
Researchers use laser light to form a tiny “optical pinhole” inside a nonlinear crystal, which also turns the infrared image into a visible image that a traditional silicon-based camera sensor can ...
