Product Description
The Grow Light HPS filter was engineered for photographers, cinematographers,
and social media managers that need to take pictures or video inside "Grow
Houses" that use High Pressure Sodium Vapor (HPS) lights to simulate daylight
during the plant growing process.
HPS lights emit a very strong and very bright color spike in the 570-590nm
(yellow/orange) area of the color spectrum. This is great for growing plants,
but horrible for taking pictures. The color is so strong that cameras can't
properly color correct it in-camera even using custom white-balance options. We
tested many different color-correction options, both in-camera and Raw
processing, with varying levels of success without using a filter. Adding the
filter, no matter how we chose to WB the room, always produced the best results
because the Grow Light HPS filter specifically targets the color spike and
blocks it from entering the camera. This allows the camera, phone, or video
camera to Auto or Custom white-balance the scene with ease.
