You know how CT is! ;-) Where the heck did all the lunar worth of mineral reflected hue or color saturation go? Why has their CCD dynamic range(DR) gotten so limited, as though restricted to only a few db or of such limited contrast bits. In the original JAXA color images, shortly before arriving at their final orbital mission placement, the moon had been looking as though quite a bluish/purple item, without any PhotoShop modifications. Are each of the JAXA/Selene HDTV telephoto and wide angle cameras selectively broken, so that moon related pixels are no longer capable of detecting a given mineral hue? .. - Brad Guth |

In 1968, Apollo 8 took the famous Earth Rise image; now the Japanese have taken a much sharper image [...] The image quality beats the daylights out of those taken by Apollo 8 in 1968. The camera on the Kayuga is digital, whereas the cameras used by Apollo were film. The technological changes in 40 years are incredible. ?? The Japanese image is HDTV, I.e., about 2 Mpixel. The Lunar Hassie was, roughly, 20 Mpixel. Yeah, that's incredible change. An order-of- magnitude change, although not for the better... Just a hint: the difference between 2 Mpixel and 20 Mpixel isn't going to be visible in a 1/4 Mpixel image, even if we ignore the effects of lossy (JPG) compression that, in this case, has thrown away over half the original data. And let's not even begin to discuss that film has a higher dynamic range (ability to record really bright things and really dark things) than any available digital media... All that being said: wow, that's a lovely image! -- Kevin Willoughby Kansas City, this was Air Force One. Will you change our call sign to SAM 27000? -- Col. Ralph Albertazzie Of one set of color pixels or 20 million of them doesn't matter. Where's the natural secondary/recoil saturation worth of photons coming off our physically dark as coal moon? Lunar minerals do have a hue or saturation of color to behold. So, why have those JAXA/Selene images been intentionally modified in order to subdue or entirely exclude the vast bulk of the natural rich colors of our naked moon? .. - Brad Guth |
