Photographic Techniques, gallery
Another group that I take cureon Flickr. Art, science, technique - this was the original meaning of τέχνη - Art-.
The main goal of an artist used to be finding the best way to express his feelings, going through any technological research that could bring benefits to his vision.
Then, Duchamp came with his "fountain".
He had a brilliant idea decontextualizing a toilet and putting it in an art gallery.
But those who keep doing it today are not so original
A group therefore that makes the photographic technique its fulcrum.
The technique used, expressed in the description of the photo, is the main requirement for your work to be admitted to the gallery.
