WebbWhile the blue filter allows NIR to be captured in the camera's red channel, a red filter blocks all visible light except for red, so the blue channel captures a very pure NIR signal. To compute NDVI, the blue channel is used for NIR and the red channel is used for red visible light, just as has been done with satellite data for 40 years. WebbFTIR Frequently Asked Questions.
