In the world there are more images representing tigers than real living ones. In our imagery, tigers are very common and seem to be everywhere: in the logos of fashion houses, on cereal boxes, on t-shirts... but they aren't. Technology can change the way we perceive reality. Three Thousand Tigers is an attempt to increase the digital fauna of an endangered animal and paradoxically refers to the idea of saving a species. The work reflects on the linguistic parallelism between the natural world and the production of images. Working with a generative algorithm Irene Fenara creates new images, big new animals and new species that arise from the union of three thousand images of tigers, the number of living animals, that ultimately retain only some characteristics of the original animal. In fact, a generative algorithm requires millions of images in order to learn how to recognize and reproduce them, thus proposing a smaller number results will be far from the reality. Generating and reproducing are the only way to save from natural and digital extinction, reflecting on the reproduction of files and how they lose quality with time and with the progress of computers and software. This is not only a natural change but also a change in the state of the images.
