Description
Nōtan 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 Nōtan in art composition is a powerful tool to help the artist identify the structure of the light and dark portions of the image they want to incorporate into their project. The first function simply divides the image into black and white with colors above the set value being white and those below being black. You can then use the slider to move that line to enhance detail that may otherwise be obscured. The second and third functions displays the image in either a grayscale or color so the artist can focus on the structure and design of the image. The next 3 functions are Levels. They set either 3, 4, or up to 10 levels of color spread over black, gray and white pallets. The 3 and 4 levels have sliders to adjust where those levels are while the Levels function just evenly divides the image by the number of levels. Finally the last function is Slice. It allows you to select a small range of values and highlight those in black and everything else white. And as of version 3.1 you can now invert the display of each of the filters. Lighter values have been displayed in white, but now you can invert them to see those in black which can really help bring out detail. 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.

I use this app to convert photographs to a posterized version for using with gel printing.
i don’t use it to paint (necessarily) i just dig the images it creates. Bravo!
I take many art classes and they always recommend this app, so you had to something right.
How do I remove this app from my apps? I do not want to pay a monthly fee for this. There’s no way to remove it. Please let me know.
Love that it just works and there are no micro transactions. Easy to use interface. whats the deal with that sound effect? seems like there could be a better way to indicate that level limit has been reached.
I paid for this app, why are you stamping your watermark on my prints?
So easy to use and so helpful.
As a Lino block artist the NotanIzer is a wonderful tool to help analyze and understand lighting and shading.
I’m an artist. Have been all my life. Recently I have started painting. I paint things that fuel my passion. If you paint Notanizer is a must have app. You can take any photo and let Notanizer do its thing and your imagination is endless. Give it a try.
Such a great tool for seeing shapes and values first. And for identifying why your painting is not coming across as exciting as your subject.
