[Jerry] recently got a shiny new DSLR camera and was looking to do something with the old Pentax DSLR it replaced. Having performed a few point and shoot IR conversions in the past, he was pretty ...

Infrared light is all around us, yet we can’t see it. That’s because the visible spectrum is only a very narrow band of the entire range of electromagnetic radiation we know as light. If you think of ...

Back in the film photography era, converting a camera to infrared was pretty straight forward. You put in some infrared film and put on an infrared filter and you were in business. With digital ...

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 ...

Photography doesn't have to be limited to traditional "RGB" image capture. All of our cameras can also record light in the infrared and UV spectrums -- if their filters are removed. You can have a lot ...

From left to right: Schematic of the nonlinear optical mirror used for up-conversion imaging. Energy diagram showing the sum frequency generation process used for up-conversion. Representative ...

Capturing photos beyond the visible spectrum is challenging and requires special gear, but the creative payoff is worth it. Here are some of my favorite infrared shots and tips to get you started.

Researchers have developed the centuries-old idea of pinhole imaging with a modern twist to create a high-performance system for converting middle-infrared light into visible light, all ...
