Moire Effect: Index and the digital image

The moire effect and phenomena are natural occurring geometric formations that appear during the super-position of grid structures. Most widely recognisable in colour printing practices, generally viewed on screens (computer and TV) they are in most cases examples of interference within a signal or code, unwanted visual mis-alignment. Especially in digital image capture, moire patternings appear when a geometrically even pattern, like a fabric or close-up of fine texture, has an appearance of rippled water with blue or red hues of concentric circle formation. The intriguing pattern formation in this case points back not only to the mis-alignment of frequencies but can be further seen as the intersection point of a speculative ontology for the index of the digital image. Moire not only as a visually reproducible phenomenon or effect, but a field of vision that blurs the boundaries between analogue and digital perception and affect. The philosophy of Henri Bergson, Brian Massumi and Francois Laruelle will be explored alongside the moire image, underlining the speculative becoming of the digital image formation and its repercussions in contemporary digital culture.
