Light is a constant "variable" in visual arts.
I know: it sounds strange…
Constant because it is the light to make visual arts possible. No light, no sight.
Variabile because it is what it is, it changes constantly.
When you happen to have some studio experience, with light so in control, you learn to appreciate the splendid serendipity of natural light.
Somebody says "Good light" as a greeting. Somebody else says there is no such thing as good or evil light, but just light.
Natural artist love “golden light” at dawn or sunset.
Maybe everybody is right and everybody is wrong.
There are moments when the subject is the light itself, its colour, the abstract shadows it generates. In other moments the main character will be what it's lighted and the singular side of it the light is revealing.
In my opinion, another "constant variable" exists, whom is regularly there, every time, although we don't always see.
Constant because it's there, always.
Variable because it changes, every moment.
To have an image there must be light, it's clear.
To have an image that light must hit something, it's true.
To have an image there must be an eye capable not just of watching, but of truly seeing. Above all.
These are the components of a tale, all of them essential.
Something to say, a particular angle, a storyteller.
The inspiration is born by these three "variables" coming together.
And yet, in the most golden of the all the lights, in the awe of most glorious of the landscapes, if behind those eyes no soul breaths, nothing will be created.
