NEW GUIDE: Retroreflective Greenscreen Light Ring QT Py Controller @adafruit @johnedgarpark #adafruit

New Guide Alert: John Park’s Retroreflective Greenscreen Light Ring QT Py Controller Guide will show you how to create a versatile chromakey backdrop and lighting controller.

From Zoom calls to SciFi effects films — you can do it all with a DIY chromakey background made from retroreflective fabric, lit with a lens-mounted NeoPixel light ring. A QT Py microcontroller running CircuitPython allows you to control the light ring color and brightness with a push and twist of a rotary encoder knob.

Traditional greenscreen/bluescreen backgrounds are tricky to light evenly, and require a lot of space to prevent your subject from casting shadows and receiving green/blue spill. This retroreflective screen solves all of these problems — and costs less, too!
