Infrared filter of camera filter

For a long time, infrared photography has been an alternative way of shooting. The images taken are shocking and unforgettable, and it also plays an important role in public security, archaeology, medicine and other fields. However, early infrared photos need to be equipped with infrared filters and special infrared films. The high cost of films and the unpredictability of shooting make many friends flinch. In recent years, with the popularity of digital cameras and home video cameras, especially after Sony first introduced night vision, people began to be interested in infrared and its photography, because CMOS/CCD photosensitive elements used in digital cameras and video cameras can receive infrared wavelengths. Now we can take infrared photos and dynamic scenes only with infrared filters, and it is more convenient to understand and observe the strange infrared world in a WYSIWYG way! There are a lot of infrared rays in sunlight, but the visible light is stronger, which interferes with your infrared shooting and overexposed the picture, so you need to add an infrared filter to filter the visible light and get a pure infrared effect; In the dark night, nature has filtered all the visible light for you, so naturally you don't need any filters. Of course, you need an infrared lamp to assist in lighting.

Infrared photography tips and some available infrared lens specifications: infrared introduction: sunlight contains rich and varied rays, and of course it also contains infrared light. When sunlight is reflected from an object to our eyes, we have actually received infrared light, but our optic nerve does not respond to it. Principle of infrared photography: ordinary cameras can also receive infrared light, but ordinary negatives can't sense it. It needs to be equipped with infrared filter and special infrared film to get it.

The CCD/CMOS photosensitive elements used in digital cameras/video cameras (hereinafter referred to as cameras) can sense infrared rays. In order to ensure that normal shooting will not cause color shift due to infrared interference, camera manufacturers are equipped with ICF in front of CCD to block infrared rays and pass visible light. Contrary to ICF, the function of infrared filter is to block visible light and let infrared light pass through. A camera with night shooting function is to remove this ICF by mechanical device, so that CCD can fully receive infrared rays! There are many infrared rays in sunlight, but the visible light is stronger, which will interfere with your infrared shooting effect, so you need to add an infrared filter to filter the visible light and get a pure infrared effect; In the dark night, nature has filtered all the scenery for you, so naturally you don't need any filters. Of course, you need the help of an infrared lamp. 1, infrared sensitive imaging equipment 2, infrared filter 3, sufficient infrared rays, which can play an important role in infrared shooting in the fields of public security, archaeology, medicine and so on through the limited visible light of some substances. It should be mentioned that it is forbidden by law and morality to use infrared features to shoot against the rights and interests of others. Photography lovers should remember not to shoot infrared in public or in front of people who don't know, so as not to inadvertently cause personal injury to others and bring unnecessary trouble to themselves. translate
