Infrared photography: Oslo at 760+ nm Infrared photography is fascinating. It takes some skill to imagine what objects will look like after the camera filters out the visible light, and (often) we turn the saturation slider to a minimum. I have been thinking of a post (or a series) dedicated to infrared photography. I will start with some examples that I have taken using a 760 nm filter on a camera whose IR-cut filter has been removed from the sensor. To clarify succinctly, silicon sensors are quite sensitive to near-infrared light, i.e., light that is "a bit redder" than red. Our eyes' limit lies at about 700-720 nm. I can see some dim objects through my 720 nm filter, but it might be leakage of red light. On the other hand, sensors can see up to 1000 nm... https://ecency.com/hive-194913/@taimen/infrared-photography-oslo-at-760
