(From Wikipedia:) Sequential art refers to the art form of using a train of images deployed in sequence[1] to graphic storytelling or convey information. The best-known example of sequential art is comics, which are a printed arrangement of art and balloons, especially comic books and comic strips.
The term is rarely applied to other media, such as film, animation or storyboards. Scott McCloud notes that the movie roll, before it is being projected, arguably could be seen as a very slow comic.
What happens when you display multiple images together, one after the other? between two (or more) images is where the magic happens, because that's where are brains are at work, making millions of connections to understand the relationship between the images.
Sequential images have the power to tell stories beyond what their static counterparts are capable of doing. When one image is followed by another, a range of thoughts and ideas spring to the mind of the viewer, as a way to process and understand the relationship between the two images. The human mind endlessly seeks out these relationships. How about these images, do you understand each one completely? Did you "get" them right away? Or was there a slight time lapse? OPD will infrequently post about this topic, because understanding and utilizing images at their best, is one of the most powerful tools we have as visual communicators and as readers.
