Comparatively new is also a further variety of the reality-photo: the negative print. The principle of inversion is known in arrangement of abstract forms, as applied in weaving and basket-work .... This specifically photographic charm cannot be experienced elsewhere, for the distinction between a day and night view of the same reality is quite a different thing.
The photogram hovers excitingly between abstract geometrical tracery and the echo of objects. In this tension there often is a peculiar charm. These pictures are taken without a camera, by the meeting of objects with sensitive paper. By exposing them a long or a short time, holding them close or far, letting sharp or subdued artificial light shine upon them, schemes of luminosity are obtained that so change the colour, outline and moulding of objects as to make them lose body and appear but a lustrous strange world and abstraction.
