720nm Mainly for digital cameras without infrared function (or when the infrared camera is in non infrared shooting mode) Because 720 passes more visible light, infrared effect and visible light color coexist. Through some shooting skills and post-processing, color pictures with semi-infrared effect can be obtained, which is another spectacle compared with pure infrared pictures taken by high wavelength filters 760nm 1 \ for models with infrared function (DV / DC): outdoor and indoor venues in cloudy days 2 \ DC long-time exposure shooting with camera without infrared function can obtain more pure infrared scenery than 720 850nm The infrared model is suitable for 850 than 950 to pass through more infrared rays
