Effect passes only infrared rays above 720nm Infrared film is also sensitive to ultraviolet rays and the shorter wavelengths of the visible so it is necessary to filter out all but the infrared rays This filter can also be used to achieve an \"X-Ray\" effect Filters can be used in baby monitoring applications. Using an infrared light source, the parent can view the child in complete darkness without having to turn on a light and disturb child.

Common problems of IR filters Hotspots Hotspots are a relatively common problem with infrared. It is due to internal reflection of light inside a lens. Normal lenses have coated barrels to absorb light, but these coatings don’t always work in infrared, causing these problems. Solution: ots can often be eliminated by changing the aperture. ots occur most often in the same type of shooting angles that cause lens flare. In this case, hotspots can usually be avoided by shooting away from bright sources of light. Exposure: On converted cameras, the exposure meters still work based on visible light. This can occasionally cause some under or over exposure because the visible and infrared light of a scene may not be the same. Package Includes: 1PiecexIR Filter 1PiecexEnglish User Manual Note: Please set a custom white balance of your way to set different cameras may vary,please check your manual. The exposure time is relatively long when using IR filters, a tripod is necessarily needed at this also suggest you to use a cable release in case shake happens.
