大气对高空摄影的影响十分复杂,本文只就大气对景物亮度的影响,大气对景物对比度和分辨力的影响作一粗浅的探讨.一、大气对景物亮度的影响地面景物的明亮程度除了与它本身的反射特性有关外,还取决于照射光的强弱.地面景物所获得的光照主要来自太阳,在地球大气层的顶部,总照度约为135千勒克司,当太阳高度角为90度时,照到地面水平面上的照度却只有约100千勒克司,其余部分被大 The impact of the atmosphere on aerial photography is very complex, this article only on the atmosphere on the brightness of the scene, the atmosphere on the contrast and resolution of the scene to make a brief discussion of the impact of the atmosphere on the brightness of the scene in addition to its brightness Its own reflection characteristics, but also depends on the intensity of light exposure.Ground scenery obtained mainly from the sun, at the top of the Earth’s atmosphere, the total illumination of about 135 kcal, when the sun’s elevation angle of 90 degrees, According to the ground level of illumination is only about 100 kilograms Division, the rest is large
