ReciprocArt

← Gallery

ReciprocArt is a project to explore the mesmerizing diversity of the Fourier space. Every image is the result of a Fourier transformation (FT) of a custom-made pattern: you can flip between them by clicking on each image.

FT is a mathematical processing method that, when applied to an image, produces a new one containing a spectrum of all pixel–pixel frequencies present in the starting image. Such spectra exist in what is known as Fourier space or ‘reciprocal space’, where features are linked to order and disorder in the distribution of pixel intensities in the original image.

Every pattern is original when not stated otherwise. To obtain sufficient inter-pixel correlations for avoiding artefacts in reciprocal space, many of the following FT images are created from an extension of their corresponding pattern. The size of this extension is included in the caption (e.g., ‘crystal size’).

All my creations are protected by an ‘all rights reserved’ copyright. If you want to own one, you can reach out to arrange a unique version for you. I never make any pattern twice, so your image will be absolutely unique.
