How did laszlo moholy-nagy create photo-grams and why?

László Moholy-Nagy created photograms by placing objects directly onto photographic paper and exposing it to light, allowing the shapes of the objects to form silhouettes and patterns without a camera. He was drawn to this technique as a means of exploring the interplay of light and shadow, emphasizing the materiality of the photographic medium. Moholy-Nagy believed that photograms could reveal the essence of objects and their relationships, aligning with his fascination for abstraction and experimentation in art. This innovative approach was part of his broader mission to integrate art and technology, fostering new visual experiences.
