Notan is a Japanese design concept involving the play and placement of light and dark elements next to the other in the composition of art and imagery. The Yin Yang symbol is an example of this design philosophy. The use of Notan in art composition is a powerful tool to help the artist identify the light and dark portions of the image they want to incorporate into their project. NotanIzer does this in 3 ways.The first function simply divides the image at 50% of bright/dark. You can then use the slider to move that line to enhance detail that may otherwise be obscured.The second function displays the image in a grayscale color palette so the artist can focus on the structure and design of the image.The third is a 4 level version. Breaks down your image into 4 adjustable levels of brightness.And of course, share your image in many ways.Any artist will benefit from seeing their work in a different light. NotanIzer is that light.
