I have been catching up on Light is my Business. Love the Solar film despite the false colour. I sent it to John Vallerga with whom I am collaborating on a Solar installation in the landscape.
We are hoping to be able to install five spectroheliostats on Angel island from where we will project large bands of sunlight that have been dispersed by prisms into 8 intense spectral colours.
We can project these over quite large distances but at about 4 kilometres, a person standing in the spectral band will see brilliant coloured stars apparently hovering on the skyline of Angel Island.
When seen with the naked eye, the changing coloured points of light have a brilliance unlike any other. One will be looking at a small part of the sun.
I have recently spoken with Anna Wirz-Justice PhD, Professor Emeritus Centre for Chronobiology in Basel, Switzerland about our project and whether receiving a direct solar reflection through one's eye into the brain might have some effect on our circadian biological rhythms. She is quite sceptical about this possibility but my experience is that seeing these directly results in an immediate change of mood. Of course, that can happen when the sun peaks out of clouds on a grey day. My very first experience seeing sunlight refracted through a prism, not reflected onto a wall or even as a rainbow in the sky, but receiving that light directly into my pupil, was on approaching a shop selling optical equipment. The day was sunny but I was depressed and everything seemed grey to me until quite suddenly my eye was filled with a brilliant coloured light: RED, YELLOW< GREEN...the colour changed as I walked. It was as if my whole being was instantly filled with light: illuminated. The depression I was feeling dissolved as if it had never existed. I would like to think this might happen to other people on seeing our installation. Anna and I are going to continue talking about this to see whether there might be some physical biological explanation.
Here is a url of our website for Solar Beacon, a white light installation John and I created for the 75th anniversary of the Golden Gate Bridge in 2012. http://www.solarbeacon.org <http://www.solarbeacon.org/>
Another url of a video I took of our tests on the Headlands in 2008 shows the bright 'stars' seen from Issey Field and the spectral bands reflected off the water. I should add here that there is a very large difference between what the camera records and what is seen with the naked eye. The camera doesn't have CONES! The eye sees much brighter, larger more exciting points of light.
I like to mention the ancient Greek word Endios, meaning brilliance or in the light, a word that preceded Theos, and in my opinion is much more meaningful.
By the way, when artist in residence at Space Science Laboratories in 2005, I was given some solar sound data.There has also been some work done on using solar data to create music.
I will continue reading.
all best
