|Research on solargraphy from analogic to digital photography|
I am enchanted by Solargraphs, because in them, the world reveals things to us we would normally not be able to see.
The track of the sun across the sky changes according to the position of the observer in relation to geographical latitudes. The main question in my research is: How different are the movements of the Sun at different latitudes? Of course it is possible to caunt the angles but I am interested in seeing this phenomenon in the images including the landscapes or view all over the world from different places. I want to see the midsummer nightless Sun in solargraphs. In the northern hemisphere in the Arctic Circle the Sun does not at all go beneath the horizon in midsummer. Earlier, this kind of phenomenon was photographed by multi exposing a photograph and as a result several Suns were seen in the same photograph. But now this solargraphy method registers the tracks of the movements of the Sun as continuous lines, not freezing several Suns. Because of the low sensibility of photographic paper it is possible to exposure for even several months. I find the vertical tracks on the equator and horizontal lines near the poles of great interest.
The sky with the movements of the Sun is not sufficient: the landscape or the urban view in cities tells us about the context and the athmosphere of the places need to be present.
This research is a pragmatical, experimental and cooperative art work. In testing different emulsions of black and white photographic papers, I have noticed there are differences between photosensitive papers. The theme for researching solargraphy is current in the change of analaogic and digital photography. The world has rapidly become digitalised and the internet is a good tool for keeping in contact with participants from all around the world. I wanted to use the simplest instrument possible for registrating the tracks of the Sun. Solargraphy allows us to see the phenomena of nature and makes the invisible visible, in the essence of photographing in using analogic and digital image processing. Without sunlight none of the Sun´s movements are visible in solargraphy. When the pinhole camera is facing the Sun and inside the camera a piece of light sensitive material is given to overexpose, the tracks will be visible through heat and sunlight without using any chemicals.
