On 4th July 2005 NASA‘s Deep Impact spacecraft attempted an extraordinarily daring encounter with the far-flung comet Tempel1.
Hurtling through space at tens of thousands miles per hour the comet‘s size, shape and other characteristics were not entirely
known and contact dangerous. When viewing a comet in visible light from very far away, only reflected sunlight can be seen, so
a big, dark comet can look the same as a highly reflective, small comet. Two of NASA‘s eyes in the sky, the Spitzer and Hubble
Space Telescopes,watched the comet from their orbits high above the Earth and together they came up with the best estimates
of the comet‘s size, shape, reflectivity and rotation rate. (NASA, SPITZER SPACE TELESCOPE)
Photography is a medium with a flat surface and any space depicted in it can only be suggested. The process of transformation that
takes place when a three-dimensional space in front of the camera is transformed into a two-dimensional image is determined by
colours, reflections, transparent or semi-transparent elements etc., which can create a depth of field or on the contrary stress the
flatness of the photographic image. Scale, perspective, the flattening or deepening functions of different lenses, the accentuation of
fore-or background and digital manipulation are the tools to suggest space in the medium of photography, that will nevertheless
always remain two-dimensional. These boundaries between actual and imagined space emphasize the qualities of photography as
an image. The two-dimensional representation is distanced from the original source and reveals photographic image as an abstract
construction rather than a documentation or a trace or reality.
