Do you or anyone else happen to know the sensitivities of phone cameras to infrared bleeding into the visible spectrum, esp under interference from the rest of the visible spectrum?
- bschwindHN 9y agoI don't have any hard science for you, but I have noticed that iPhones do a significantly better job at filtering infrared compared to the Android phones I own (mostly older Nexus devices). I typically use an Android to see if LEDs are emitting instead of my iPhone because it's so much fainter on the iPhone. The photo in my article was taken with an Olympus mirrorless camera.
- friendzis 9y agoDisclosure: not an expert. IR/UV bleeding depends mostly on 3 things: sensor sensitivity, materials of and coatings on lenses, raw sensor data processing. Professional cameras are usually equipped with IR blocking filters and UV filter is "standard practice". Results can vary drastically from seeing under clothes [1] to barely registering IR lighting.
