Cette image d\u00e9finit le format, la grille et la r\u00e9f\u00e9rence chromatique de la mosa\u00efque. Selon le niveau d\u2019influence choisi, elle peut \u00e9galement \u00eatre superpos\u00e9e par transparence \u00e0 la mosa\u00efque, avec une opacit\u00e9 de 0, 25 ou 50 %.\u00a0<strong>Chaque image est destin\u00e9e \u00e0 dispara\u00eetre.<\/strong><\/p>\n<p>Les mots-cl\u00e9s ne g\u00e9n\u00e8rent pas l\u2019image. Ils filtrent les donn\u00e9es locales et permettent d\u2019interroger les collections ouvertes. Les images collect\u00e9es sont pr\u00e9par\u00e9es en fragments, puis chaque fragment est analys\u00e9, compar\u00e9 et plac\u00e9 selon sa proximit\u00e9 chromatique avec une cellule de l\u2019image-source. La mosa\u00efque se construit progressivement, cellule apr\u00e8s cellule.<\/p>\n<p>Certaines zones peuvent rester vides parce qu\u2019aucun fragment ne r\u00e9pond aux conditions du protocole, ou parce qu\u2019un degr\u00e9 d\u2019inach\u00e8vement a \u00e9t\u00e9 choisi volontairement. Ces vides rendent visibles les limites et les d\u00e9cisions du syst\u00e8me de recomposition. Le manque est une donn\u00e9e du protocole, pas un d\u00e9faut de fabrication.<\/p>\n<p>Une image n\u2019est jamais produite une fois pour toutes. Elle traverse successivement les \u00e9tats de construction, de pr\u00e9sence, de stabilit\u00e9, d\u2019\u00e9rosion, de disparition et de trace. La disparition n\u2019est pas une op\u00e9ration ext\u00e9rieure : l\u2019ordre exact de construction est enregistr\u00e9, puis l\u2019\u00e9rosion le suit en sens inverse. La derni\u00e8re cellule pos\u00e9e est la premi\u00e8re effac\u00e9e. Chaque g\u00e9n\u00e9ration entre dans une archive \u00e9ph\u00e9m\u00e8re. Elle conserve d\u2019abord les conditions de son apparition, reste stable pendant 30 jours, puis perd progressivement ses cellules pendant 90 jours sous l\u2019effet du temps. Lorsque le stockage du projet approche de sa limite de 5 Go, sa pression acc\u00e9l\u00e8re cette \u00e9rosion. \u00c0 0 % de pr\u00e9sence, l\u2019image, l\u2019image-source soumise et les fichiers d\u00e9taill\u00e9s sont effac\u00e9s du serveur. Seule subsiste une trace minimale de la disparition. L\u2019archive conserve moins des objets qu\u2019elle ne rend perceptible leur passage.<\/p>\n<p>Deux types de vide coexistent. Les vides initiaux sont transparents : ils appartiennent \u00e0 la construction de l\u2019image et n\u2019ont jamais contenu de fragment. Les cellules effac\u00e9es sont opaques, blanches ou noires selon le fond enregistr\u00e9 de la g\u00e9n\u00e9ration : elles signalent qu\u2019un fragment a exist\u00e9 puis a disparu. Un vide initial ne peut jamais devenir une cellule effac\u00e9e. L\u2019image demeure ainsi lisible comme une stratigraphie o\u00f9 l\u2019on distingue ce qui n\u2019a jamais eu lieu de ce qui a eu lieu et n\u2019est plus.<\/p>\n<p>\u00c0 mesure que l\u2019\u00e9rosion progresse, la mosa\u00efque se remplit de cellules monochromes. L\u2019image, d\u2019abord compos\u00e9e de provenances h\u00e9t\u00e9rog\u00e8nes, tend vers un champ uniforme de noir ou de blanc avant de dispara\u00eetre compl\u00e8tement. Le protocole ne d\u00e9truit pas seulement : il convertit une h\u00e9t\u00e9rog\u00e9n\u00e9it\u00e9 en monochrome et fait du monochrome l\u2019\u00e9tat terminal de toute image.<\/p>\n<p>Le visiteur peut t\u00e9l\u00e9charger l\u2019\u00e9tat actuel d\u2019une image. Cette copie locale n\u2019interrompt pas le protocole de disparition sur le serveur : l\u2019image continue de dispara\u00eetre pendant que la copie subsiste ailleurs. Le t\u00e9l\u00e9chargement met imm\u00e9diatement fin au droit temporaire de supprimer la g\u00e9n\u00e9ration. La conservation devient une d\u00e9cision individuelle, ext\u00e9rieure au dispositif, et non une propri\u00e9t\u00e9 de l\u2019archive.<\/p>\n<p>La r\u00e9activation de\u00a0<em>Des Frags<\/em>\u00a0ne consiste donc pas \u00e0 restaurer une forme ancienne. Elle d\u00e9place le projet vers un environnement contemporain fait de corpus, d\u2019API, de collections ouvertes, de calculs de similarit\u00e9 et de limites visibles. Le fragment n\u2019est plus seulement un morceau d\u2019image : il devient l\u2019unit\u00e9 d\u2019un processus de construction, d\u2019\u00e9rosion et de disparition.<\/p>\n<blockquote class=\"instagram-media\" style=\"background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);\" data-instgrm-permalink=\"https:\/\/www.instagram.com\/reel\/DcV8ozlpTDx\/?utm_source=ig_embed&amp;utm_campaign=loading\" data-instgrm-version=\"14\">\n<div style=\"padding: 16px;\">\n<p>&nbsp;<\/p>\n<div style=\"display: flex; flex-direction: row; align-items: center;\">\n<div style=\"background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;\"><\/div>\n<div style=\"display: flex; flex-direction: column; flex-grow: 1; justify-content: center;\">\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;\"><\/div>\n<\/div>\n<\/div>\n<div style=\"padding: 19% 0;\"><\/div>\n<div style=\"display: block; height: 50px; margin: 0 auto 12px; width: 50px;\"><\/div>\n<div style=\"padding-top: 8px;\">\n<div style=\"color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;\">Voir cette publication sur Instagram<\/div>\n<\/div>\n<div style=\"padding: 12.5% 0;\"><\/div>\n<div style=\"display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;\">\n<div>\n<div style=\"background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);\"><\/div>\n<div style=\"background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);\"><\/div>\n<\/div>\n<div style=\"margin-left: 8px;\">\n<div style=\"background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;\"><\/div>\n<div style=\"width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);\"><\/div>\n<\/div>\n<div style=\"margin-left: auto;\">\n<div style=\"width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);\"><\/div>\n<div style=\"background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);\"><\/div>\n<div style=\"width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);\"><\/div>\n<\/div>\n<\/div>\n<div style=\"display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;\">\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;\"><\/div>\n<div style=\"background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;\"><\/div>\n<\/div>\n<p>&nbsp;<\/p>\n<p style=\"color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;\"><a style=\"color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;\" href=\"https:\/\/www.instagram.com\/reel\/DcV8ozlpTDx\/?utm_source=ig_embed&amp;utm_campaign=loading\" target=\"_blank\" rel=\"noopener\">Une publication partag\u00e9e par Reynald Drouhin (@reynalddrouhin)<\/a><\/p>\n<\/div>\n<\/blockquote>\n<p><script async src=\"\/\/www.instagram.com\/embed.js\"><\/script><\/p>\n<hr \/>\n<p><em>Des Frags Process<\/em>\u00a0is a reactivation of\u00a0<a class=\"inline-art-link\" href=\"https:\/\/red.reynalddrouhin.net\/archive\/desfrags\/\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Des Frags<\/em><\/a>, a project first released online in 2000.<\/p>\n<p>The work takes a source image and submits it to a protocol of recomposition. This image defines the format, the grid and the chromatic reference of the mosaic. Depending on the selected influence, it can also be overlaid transparently on the mosaic at 0, 25 or 50% opacity.\u00a0<strong>Every image is destined to disappear.<\/strong><\/p>\n<p>Keywords do not generate the image. They filter local data and enable searches in open collections. Collected images are prepared as fragments, then each fragment is analyzed, compared and placed according to its chromatic proximity to a cell of the source image. The mosaic is progressively constructed, cell after cell.<\/p>\n<p>Some areas may remain empty because no fragment answers the conditions of the protocol, or because a degree of incompletion has been deliberately chosen. These voids reveal the limits and decisions of the recomposition system. Absence is a datum of the protocol, not a fabrication defect.<\/p>\n<p>An image is never produced once and for all. It successively passes through construction, presence, stability, erosion, disappearance and trace. The disappearance is not an external operation: the exact order of construction is recorded, and erosion follows it in reverse. The last cell placed is the first erased. Each generation enters an ephemeral archive. It first preserves the conditions of its appearance, remains stable for 30 days, then gradually loses its cells over 90 days. When the project storage approaches its 5 GB threshold, storage pressure accelerates this erosion. At 0% presence, the image, the submitted source image and the detailed files are erased from the server. Only a minimal record of the disappearance remains. The archive preserves objects less than it makes their passage perceptible.<\/p>\n<p>Two kinds of void coexist. Initial voids are transparent: they belong to the construction of the image and have never contained a fragment. Erased cells are opaque, white or black according to the recorded background of the generation: they indicate that a fragment existed and then disappeared. An initial void can never become an erased cell. The image remains readable as a stratigraphy distinguishing what never took place from what took place and is no longer there.<\/p>\n<p>As erosion progresses, the mosaic fills with monochrome cells. The image, initially composed of fragments of varied provenance, tends toward a uniform black or white field before disappearing completely. The protocol does not merely destroy: it converts heterogeneity into monochrome and makes monochrome the terminal state of every image.<\/p>\n<p>The visitor can download the current state of an image. This local copy does not interrupt the server-side erasure protocol: the image continues to disappear while the copy persists elsewhere. Downloading immediately ends the temporary right to delete the generation. Preservation becomes an individual decision outside the system, not a property of the archive.<\/p>\n<p>Reactivating\u00a0<em>Des Frags<\/em>\u00a0therefore does not consist in restoring an earlier form. It moves the project into a contemporary environment made of corpora, APIs, open collections, similarity calculations and visible limits. The fragment is no longer only a piece of an image: it becomes the unit of a process of construction, erosion and disappearance.<\/p>\n<p><a href=\"https:\/\/red.reynalddrouhin.net\/wp-content\/uploads\/2026\/07\/desfrags-process_20260804-151113-cdb526ce.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-11878\" src=\"https:\/\/red.reynalddrouhin.net\/wp-content\/uploads\/2026\/07\/desfrags-process_20260804-151113-cdb526ce.png\" alt=\"\" width=\"594\" height=\"660\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>2000-26, application web g\u00e9n\u00e9rative<\/p>\n","protected":false},"author":3,"featured_media":1401,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"jetpack_post_was_ever_published":false},"categories":[69,4],"tags":[131,831,634,817,819,823,818,815,389,833,834,832,812,108,77,822,816,581,828,829,820,830,44,78,29,800,826,80,814,335,802,837,813,904,821,835,291,81,827],"class_list":["post-1394","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-internet","category-photographie","tag-appropriation","tag-archive-ephemere","tag-base-de-donnees","tag-cellule","tag-collecte","tag-collections-ouvertes","tag-corpus","tag-defragmentation","tag-disparition","tag-effacement","tag-entropie","tag-erosion","tag-fragmentation","tag-generatif","tag-grille","tag-image-trouvee","tag-image-matrice","tag-impermanence","tag-inachevement","tag-incompletude","tag-indexation","tag-manque","tag-memoire","tag-mosaique","tag-mot-cle","tag-net-art","tag-open-access","tag-participatif","tag-photomosaique","tag-processus","tag-protocole","tag-reactivation","tag-recomposition","tag-reload","tag-requete","tag-stockage","tag-trace","tag-trame","tag-vide"],"jetpack_publicize_connections":[],"jetpack_shortlink":"https:\/\/wp.me\/p72hz6-mu","jetpack_sharing_enabled":true,"jetpack_featured_media_url":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-content\/uploads\/2026\/07\/desfrags-process_20260724-233145-cc18e3cb-scaled.jpg","_links":{"self":[{"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/posts\/1394","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/comments?post=1394"}],"version-history":[{"count":9,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/posts\/1394\/revisions"}],"predecessor-version":[{"id":1460,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/posts\/1394\/revisions\/1460"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/media\/1401"}],"wp:attachment":[{"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/media?parent=1394"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/categories?post=1394"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.reynalddrouhin.net\/wrks\/wp-json\/wp\/v2\/tags?post=1394"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
