The right-hand photo is a natural-color image taken with MISR's 70-degree backward viewing camera, which uses the reflectionof lightto enhance the polar clouds' appearance.
右图是用多角度成像光谱仪的70度后视相机，利用光线反射增强极地云的外观拍摄的自然色图像。

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired this false-color image of the landslide lake on June 1, 2010 - now 16km (10 mi) long.
The variations of object's reflection light induced from illumination variations and uneven illumination distribution greatly reduce the detecting efficiency in the process ofcolor object detection.
