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!
