Hi, Doug,
I think it needs a lot of further research - saying it rates aesthetics
is more than silly.
I've been trying out various shots on it - it seems to want to tell me
to stop taking pictures of steam trains - nothing higher than 29% - of
course the main subjects are almost always dark and in the middle of the
frame.
I think it must work, at least partially, on distribution of contrast
and brightness and a certain light shade in the perceived focal point of
the image within a rule of thirds coordinate system with weighted zones
- it doesn't seem to be particularly bothered about colour, although I
did notice that many of the high rating colour shots are very dark. It
also doesn't care whether the shots are blurred or totally out of focus.
Just for fun, I uploaded a colour bar reference chart with a gray scale
through the middle - it rated around 25%.
One thing is for sure, its verdicts on pictures cover a spectrum just as
broad as that of human viewers opinions.
I think I'll download a couple of images and take a look at the
histograms too. It's possible that it works on the same basis as this
new face recognition software.
It's got me hooked now, I want to create a totally synthetic perfect
image to find out how it works :-)
Best
Douglas

Find out for yourselves how good you really are - it's quite surprising,
and completely off track - it already relegated our own established
master of bird photography Doug Herr to below amateur status. Henri
Cartier Bresson and Dorothea Lange didn't rate too well either :-)
I managed to score 89.3 with this one, but everything else I tried was
apparently utter rubbish
http://gallery.leica-users.org/v/DMS/Sunglasses.jpg.html - Not far
behind Dorothea Lange's Migrant Mother :-)
One feature it seems to like is a bright center and darker edges, also the rule
of thirds. These two both scored quite well, apparently because they follow
the classical rules of composition:

and this rated only 30.8 (out of 100):
