An Arthouse Video
Photography — It was a sunny, Sunday afternoon when light was streaming through my back window. There was a gentle breeze that made the leaves on the tree in the back garden move to and fro. The poetic dancing shadows on my piano added a rare atmosphere. The perfect day to photograph a prism. One has to know about optimal sun position and angle in relation to planet Earth in order to make this document. I succeeded on my second attempt which was 365 days later. This type of photography can only happen on one day of the year in that location.
Light — If I was travelling on a wavelength of white light through a prism, I would mingle with the density of the crystal resulting in offspring of different types of light spread across the electromagnetic continuum as refracted light. Light is refracted on entry and exit of the prism.
Computer — Keynote software has a transition feature called ‘colour planes’ that separates red, green and blue. This knowledge sparked the idea to make a video of a prism. A secondary idea was the knowledge of a particular piece of music.
Music — The title of the music in ‘Prism Transition’ is ‘Spiegel Im Spiegel’ by Arvo Pärt, and was re-composed from four staffs to three by myself especially for the video. Spiegel Im Spiegel translates to Mirror in the Mirror and was the reason I included it in the poem ‘High Street! — Outside In, Inside Out’. Here is that very verse:
“And even more extraordinary: a reflection reflecting itself
Now everything keeps reversing and turn-turning about
Spiegel Im Spiegel melodies go round inside my head
On and on and on it goes, outside in, inside out…”
Illusions — The psychology of visual perception, the physics of refraction. A key term when thinking about mirror images, is: enantiomorphs. An object has the coordinates: x, y, z. An object as reflected by a mirror has the coordinate: – x, y, z. Therefore, when looking through a mirror one has to double the distance from the object to the mirror in order to obtain an accurate measurement of the reflection.
