China to the Moon - Chang'e program, Chinese unmanned lunar mission[/URL]
第30页440楼：
Hungry4info对比了[URL=http://target.lroc.asu.edu/q3/ ]Google Map的月球版（是亚利桑那州立大学根据NASA的月球勘测轨道飞行器相机(LROC)所拍多幅图片拼出来的)[/URL]和嫦娥三号上的降落相机所拍的图片，自己找到了着陆点：
纬度：~-19.5014， 经度：~+44.126,
这和官方公布的着陆点（19.51°W,44.12°N）是非常接近的。

第31页451楼：
Thorsten Denk对比了着陆点附近的由嫦娥的地形地貌相机（拍摄角度约为地表平视）和降落相机（拍摄角度为俯视）所拍的两张图片。

第31页462楼：
Palbo提供了非常酷的图片，分析了嫦娥三号降落相机在不同高度所拍摄的图片。

第32页474楼：
Phil Stooke也贴出了他对着陆点分析（前面几张来自于LROC和NAC（NASA Advisory Council，NASA咨询委员会），最后一张是嫦娥降落相机所拍的高清图）：

dvandorn评论了玉兔和嫦娥所拍照片的色彩。嫦娥全景相机偏深棕色。而玉兔则较为正确地（或者说符合期待地）拍出了月壤的灰色，尽管照片显得有些过饱和。
First, the images from Yutu's mast camera seem a little over-saturated. At least, the brightest elements in the images (the rock faces reflecting sunlight right back into the camera) look rather over-saturated to me.
Second, the color rendition from the lander's panoramic camera seems to be biased towards a very brown image, while the rover's color camera is registering more of the expected grayish coloration of the regolith, almost trending towards a slight greenish tinge. Interestingly, these are the same range of color biases that were achieved from the various color film stocks used during Apollo. It took until the later flights for the photo processors to achieve a consistent representation of the grayish lunar regolith; this shows how difficult it can be to get good, representative color from the lunar surface.
I wonder if the mission controllers will be adjusting the color balances and saturation in the released images as time goes on?
Also, looking forward to more of the full video feed from Yutu. That was pretty impressive from the quick flashes we saw during the rover deployment.
