What's so different about the infrared filter?
Infrared filters, sometimes called IR filters or heat-absorbing filters, are designed to allow IR mid-infrared wavelengths while blocking visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating. There are also filters that are used in solid-state (CCD or CMOS) video cameras to allow IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the shorter visible light and UV wavelengths.
In which ways the infrared filter will be used?
1.Archaeology, Military, Police, Medical science, and detective work. Infrared filters allow normally invisible stains and modified items visible.
2.Plant vegetation & Landscape photography. It looks dramatically different when photographed in Infrared.
3.Photographic special effects. Infrared filters give the still and video photographer expressive and unusual effects.
In what suitable light source should I use the infrared filters?
590nm, 600nm, and 630nm for Infrared change machine. The rich colors, custom white balance, the original film in general the sky was bright red, partial brown or amber, plant leaves, blue, sky blue saturation after post-processing, the leaves yellow or golden yellow.
680nm for indoor and weak Shadows use.
720nm for indoor and weak light use.
760nm for cloudy outdoor at nightfall and brightness indoor.
850nm for indoor and weak cloudy outdoor light.
950nm for outdoor and strong light, such as summertime.
1000nm for low latitudes and strong reflective light, such as on the beach by noontime.
