Chang'e 3 data is now available to the international community in PDS format through the Science and Application Center for Moon and Deepspace Exploration (China's version of the PDS). The website tends to be unstable; login has not worked for me all week...but it is working now. If you don't want to work through the website, I have downloaded and posted the entire available TCAM and PCAM data sets, with links and explanation in this blog entry. Have at it!

I've taken a stab at working with this data set using the demosaiced png images. Colorization was done using gmic's "bayer2rgb" routine, which for some reason spit these images out with the red channel significantly fainter than the green and blue channels. As a result I've kind of had to guess at how bright the red needs to be, so the color is probably off. I should probably grab some of the official releases to compare color.
Anyway I did some cleaning up in Photoshop (slight gaussian filter to remove the last traces of bayer patterning, a denoise filter to remove some of the color noise, and some sharpening to recover some of the detail lost with the bayer pattern removal) and here's the result: Chang'e 3 Observation 4 partial mosaic by Justin Cowart, on Flickr The problem I'm trying to tackle now is a slight color gradient between the left and right edges of the images. Although Photomerge does a good job handling overall brightness gradients, it's having a little more difficulty with the color. The neutral gray color of the terrain also makes slight variations in color stick out more. Here I've tried to reduce it with a bit of burning and dodging but I'm not entirely happy with the result. Once I get a better process down I'll probably rework this image, as well as assemble the full 360 degree panorama. |
