In 1968, Apollo 8 took the famous Earth Rise image; now the Japanese have
taken a much sharper image
http://www.jaxa.jp/press/2008/04/img/20080411_kaguya_02.jpg Shows an image
of Earth Rise taken by a Japanese probe called Kayuga
(http://www.jaxa.jp/press/2008/04/20080411_kaguya_e.html#ref01)
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.

Will the same bunch that say we never went to the moon, now say this
proves there are 5 Earths? |

Why did JAXA revise/modify those images, so as to exclude the mineral
color saturation or natural hues of the physically dark moon, along
with such a colorful Earth rising in the very same FOV?

Besides, where did all the lunar worth of mineral hue or color

Why is their CCD dynamic range(DR) gotten so limited, as though
restricted to only a few db or limited contrast bits.
In the original JAXA color images, shortly before arriving at their
final orbital placement, the moon was looking as though quite a bluish/
purple item without any PhotoShop modifications.
Are the JAXA/Selene HDTV telephoto and wide angle cameras selectively
broken, so that moon related pixels are no longer capable of detecting
a given hue?

Slick shots!
I found a whole pile of Earth-Moon images here, including a series very
similer to this from Zond 7:

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?

The Apollo 8 image is still better. Kayuga's Earth looks like a
Photoshop job.
My thought as well (and this was after I went to the site to see if there
were higher resolution versions of the new pictures).
In a lot of ways, a high end (large format) film camera is still superior to
a high end digital camera. The cameras carried by Apollo were actually very
good. Unfortunately, the astronauts were a far cry from professional
photographers, so it's not terribly surprising that the quality of many of
the photos is lacking.
However, the famous Apollo 8 earthrise photo is very good, all things
considered.

Keep in mind too that many of the pictures we've seen are copies of copies
of copies etc. They don't necessarily reflect the best production qualities
available.

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!
