Notanizer app tutorial and review

What is NotanIzer?

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 last 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.

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.

Featured Reviews NotanIzer

Useful tool for artists

I’m a painter and I use this app all the time. Super useful


Simple and eye-opening. The only thing I wish to change would be to disable that terrible sound when you try to set levels too high or low.

Easy to use, responsive dev

The UI is straightforward and makes adjusting the color levels very easy. Initially had a problem sharing the image through another app. The developer responded quickly through email and updated the program quickly to fix the issue. Very satisfied overall.

Fantastic App a strong and useful tool to artist

I'm an art insturtor of adults in Colorado and have found this app to be indespencable in teaching values. It's simple to use and effortlessly comunicates visiually the most powerful tool in art, values. I use this tool almost daily. Bravo, to you, good people at Notanizer!

Very Handy..

Yes, there are other apps that can turn things to grayscale or levels of gray, but this is quick, easy and handy. You get phone, ipad, and Masc app all for noe low price. Good deal!
