What do you mean by photo rubbing?

Photo rubbing, also known as photo silver salt printing, is a traditional black-and-white photography technique. Its principle is to print photos in a darkroom with film, and the final photos have a strong artistic sense and historical precipitation. Before the arrival of the digital age, photo rubbings used to be the main means for people to preserve their memories, and also the lifeblood for video artists to express their feelings and thoughts. Although digital cameras and smart phones can easily take high-definition and colorful photos, photo rubbing still has its unique charm and significance.

Different from other types of photos, photo development needs to be done in a darkroom, and the exposed film is moved into the developer by darkroom lighting, and then processed in the fixing solution. These operations need to be carried out in an extremely strict dark environment, because any tiny light will destroy the imaging effect of the photo. In the process of photo rubbings, image artists need to pay great attention to experiments and adjustments to obtain the best results. Although this production process is complicated and prone to accidents, this kind of labor and time investment also brings deeper and fuller details to the photos.

Today, with the continuous updating and evolution of photography technology, photo rubbings still maintain their unique taste and feeling and become more choices for photographers. For those who love video art, photo rubbings are not only a way of expression, but also a way of life. No matter how digital cameras and smart phones develop, people's memories and emotions always need to be recorded, preserved and passed on. Therefore, photo rubbing still has considerable vitality and market demand.
