1898 film Walking Troubles of Organic Hemiplegy, inspired by his earlier work using chronophotography under the influence of Marey. The short film shows patients walking in four directions against a black background before and after treatment. This and Marinescu's related films are considered early documentary films. The professor called his works "studies with the help of the cinematograph," and published the results, along with several consecutive frames, in issues of "La Semaine Médicale" magazine from Paris, between 1899 and 1902. As photography became the dominant source of accurate depiction of life, art no longer necessarily had to capture life. Now liberated from the one-to-one relationship between a fixed coordinate in space captured at a single moment in time assumed by classical vanishing-point perspective, the artist became free to explore notions of simultaneity, whereby several positions in space captured at successive time intervals could be depicted within the bounds of a single painting. Cubist works regularly depicted multiple angles within a frame, and multiple aspects of time and motion can be recognized in several related paintings, including Jean Metzinger's Danseuse au café (Dancer in a Café) (1912). Marcel Duchamp's famous Nu descendant un escalier n° 2 (Nude Descending a Staircase, No. 2) (1912) was directly influenced by Muybridge's Woman Walking Downstairs (1887) and the works of Marey. Influence Photography In 1989 Nishika N8000, a camera able to take "3D photos'', was created in Japan. The results were 4 images of the same moment with a little perspective variation created by 4 shutters of the camera which closed simultaneously. Almost like Edweard Muybridge's study of the horse movement, who put on 24 cameras parallelly along 40 meters at Stanford, the Nishika N8000's 1/60 fixed shutters with a 30mm lens are separated by no more than one centimeter. Therefore, just like Muybridge used the separation between cameras to capture the subject's movement, this type of photography tool uses the separation between shutters to capture the depth of field's movement and creates a 3D image sensation because, while the subject keeps still, the background doesn't. As the previous camera's user's manual shows (the Nimslo 3D) every light entrance fills half of a 35mm reel slide. This way, every negative has 2 images of 30mm, which merged, create 6 (look at the diagram), provoking to have 12 useful images instead of 24 images of a 24 reel. In the 21st century, there has been little
