红外线拍摄的特点红外线位于电磁波谱中的可见光谱段的红端以外,介于可见光与微波之间,波长为0.76～1000μm,不能引起人眼的视觉。实际应用中常将其分为三个波段:近红外线、中红外线、远红外线。日常摄影中的人、树木等景物反射太阳辐射中的近红外线,从而表现出自身的形状,故近红外线也称为摄影红外。人、草地对红外线反射较强,它们的黑白红外成像就较白;河流、天空对红外线反射较弱,它们的黑白红外成像就较黑。拍摄时,因为运用滤镱不同,也有纯红外效果(黑白),标准彩色红外效果和加强彩色红外效果之分。
The characteristics of infrared shooting Infrared ray is located in the visible spectrum of the electromagnetic spectrum outside the red end, between visible light and microwave wavelength of 0.76 ~ 1000μm, can not cause the human eye’s vision. In practice it is often divided into three bands: near infrared, mid infrared, far infrared. People in everyday photography, trees and other scenes reflect the near-infrared in the solar radiation to show their own shape, so near infrared is also known as photography infrared. People and grasslands have strong infrared reflections, and their black and white infrared images are whiter; river and sky have weaker infrared reflections, and their black and white infrared images are darker. Filming, because of the use of different filter ytterbium, there are also pure infrared effects (black and white), the standard color infrared effect and strengthen the color infrared effect of the points.
