I have studied western astrology for a very limited time (two years), and I have not read the article about silver and the moon... basically, I am apologizing for my ignorance before I reply.
I am also a photographer.
CAMERA
I would suggest looking at when the camera was invented in proximity to the astrological learnings of that day.
Camera obscura. John Talbot-first photograph... I think. I don't know the year.
The camera obscura, in the history of photography, was considered to be the first camera. It was a room built like a pinhole camera.
It relied upon the rays of the sun to penetrate a small hole in order to project an inverted image on the opposing wall.
I would interpret this as in terms of the MOON.
The suns bright blast reduced to a but a shadow of its potency = the moons reflection of the sun.
Reflection = inverted image
FILM
Which brings me to Neptune and the 'silver screen.'
In motion film, the image is reverted, and thus a reflection.
Neptune = an illusion
A photograph is an illusion.
As evident in politics, the way a photograph is presented, creates an illusion.
It is a stop in time that denotes what the photographer wants to suggest to the viewer.
It is recieved by the viewer, who uses his own point of reference regarding interpretation. Illusion?
Moon
True photography is silver based.
In capturing a *flick* of a moment in time, a photograph captures a rapid emotion.
Moon- fast moving and represents the emotions.
CAMERA
URANUS - the cameras history is based in science and new technology.
Photography was veiwed as an artform by those who first used a camera.
It was scoffed at by painters at the time.
They viewed the camera as a cheap imitation of what they could produce using paint.
Thus, the first photographers were 'radical.'
The mechanics of the camera are always evolving... and the device is always breaching the surface in its use of technology. In doing such, the camera lags behind the ultimate desire of what the photographer wants to hold in their hands.
MERCURY, to me, in its appearance, seems to mimic the MOON.
When young, I broke a thermometer in my hand, twice on purpose regardless of the 'warnings' of doing such. If you have done this, you know that Mercury appears to be silver. It slips and slides, and you cannot confine its shape (water moon)
MERCURY - The camera is held in the hand and contains small parts. It takes an exacting mind to design its small parts. The camera yields to, and gives its best to, precise manipulation of its parts.
Time for me to stop being long-winded.
My vote would be
