Photomicrographs of my project "Pure Photography": Photography is "drawing with light". Pure photography means that the light itself, its color and/or its brightness creates an abstract image on a light-sensitive medium (film or camera chip) without beeing affected by a subject from the human world of experience. In this experimental microphotographic project the aim is not the imaging of an object, but rather an optically active sample (pinhole, slit, grating, opaque stop, spherical lens etc.) is used to modulate the light beam normally used to create a magnified image of a microscopic object. Thus, I study the artistic possibilities of pure photography using the physics of light and of light microscopy
