The algorithms, which are supposed to square our gaze, open us up to the unsuspected poetry of the world.

Series of 27 photos, treated with the “seam carving” technique, which reveals a disturbing strangeness.

The seam carving or intelligent cropping, is an image resizing algorithm developed by Shai Avidan and Ariel Shamir. This algorithm resizes, not by conventional scaling or cropping, but by removing so-called minor pixel paths (seams).

The importance of a pixel is usually measured by its contrast compared to its closest neighbours, but other techniques, such as shape detection, can be used. In addition, it is possible to define, or automatically detect, areas of great importance, and thus protect them from deletion. Conversely, you can define areas that can be removed first. From this information, the algorithm detects lower energy paths, and removes them.

Because of the mechanical nature of its technical function, photography is for me a matter of time rather than a visual matter : in its silver salts, or its pixels today, it is time which is captured, preserved, reinvented at every glance. Time of life, time of vision, time of poetry.Painting is the original material of plastic work, which is intimately connected with photography, because it also contains the time of its gesture and its imagination.Artistic installation, the existence in space and time of artistic forms is crucial because it is the way in which the work is modified by (...)
