Fotga filter Optical Circular Adjustable IR Pass X-Ray Variable 530nm to 750nm Six-in-One Lens Filter for Infrared Photography

• Infrared filters, sometimes as IR filters or heat protection filters are designed to allow IR medium infrared wavelengths while blocking visible light. They are often used in devices with bright bulbs (such as slide and overhead projectors) to prevent unexpected heating.
• There are also filters that are used in fixed condition (CCD or CMOS) video cameras due to the high sensitivity of the camera, many sensors near infrared light are possible to IR These filters typically have a blue colour as they sometimes block some of the light from the shorter visible light and UV wavelengths.
• Digital cameras are usually equipped with IR cut filters to prevent unnatural looking images. IR transmitting (passing) filters, or removal of the factory IR blocking filters, are commonly used in infrared photography to pass through infrared light and block visible and ultraviolet light. These filters appear black around the eye, but are transparent when viewed with an IR sensitive device.
• The creative adjustable IR filter is a compact all-in-one variable wavelength filter that adjusts the amount of wavelengths, with exactly the torsion of your wrist. The index markings on the filter allow you to know exactly the amount of wavelengths at a glance. Give clear and precise shoes at each wavelength you use. It offers you the freedom to create different wavelengths freely.
• You don't have to carry out a range of filters for shooting. Just one filter, releases you from the range of 530nm to 750nm.

Please note: - You should remove the IR blocking filters before the CCD or CMOS sensor when using IR filters - Setting the white balance - If you do not want to do any transformation on the device, you can do some post-processing after recording to achieve the IR effect. In which way the infrared filters are used? - Archaeology, military, police, medical science and detective work. Infrared filters usually leave invisible stains and changed objects visible. - Plant vegetation and landscape photography It looks completely different when photographed in infrared. - Photo special effects. Infrared filters give the photo and video photographers expressive and unusual effects. In which suitable light source should I use the infrared filters? - IR filter can block all visible light under similar wavelengths and very sensitive to UV rays. - 590nm, 600nm and 630nm for the infrared automatic changing. The rich colours, individual white balance, the original film in general was the sky bright red, partially brown or yellow, factory leaves, blue, light blue saturation after post-processing, the leaves yellow or golden yellow. - 680 nm for indoor and weak shadows to be used. - 750nm for indoor and weak bright use. - 760nm for cloudy outside at dusk and brightness inside.
