## NotanIzer 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 downloaded to my mac and images would just come out white.
-- frankenstienchevy, 2024-06-09

### ***** "art tool for notan"
artists you know how important it is to get values right. this app lets you create a symphony of values and get good values-think.
-- painting in seattle, 2024-05-11

### ***** "Notan love"
Love this app. It helps me with all of my artwork as I play with the possibilities!  Thanks!!!!!
-- Dksmyers, 2024-01-05

### ***** "good app"
really simple ui and did exactly as advertised. id say it’s a good investment, but you can definitely find free apps with b&w sliders if ur just looking for that
-- Asapwhitters, 2023-03-06

### ***** "Great tool"
Really helps me see shapes and contours!  Use in drawing studio a lot.
-- Newmusicworthtrying, 2023-02-19

### **--- "Limited Features"
I really wish there were a way to save a NAMED file to my mac. The only current option I see is to save it to the Apple Photos app with a predefined name.

Saving your image in the folder of your choice seems like an essential feature that should be there. I should not have to do multiple steps to get one image to my chosen location.
-- Fritz Schnickelgruber, 2022-12-31

### ***** "Useful tool for artists"
I’m a painter and I use this app all the time. Super useful
-- Tracy7643, 2022-08-01

### ***** "Wonderful"
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.
-- Flayra, 2022-07-01

### ***** "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!
-- Colorado Stevie Bee, 2021-06-24

### ***** "Like this a lot"
This is a great tool for Plein Air painting
-- outside painter, 2021-05-25

### ***** "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.
-- Splurch42, 2021-05-10

### ***** "Absolutely a Great App for Artist"
I love the fact that you can do things on a phone App that used to need the computer and Photoshop! I use it all the times to check my portraits!
-- wlmsgrp, 2021-05-02

### ***** "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!
-- Troutco, 2021-03-27

### ***** "Notanizer"
I wrote a negative review and was contacted by someone who “fixed” the issue I had. I’m now giving a five star rating because of the exemplary customer service and the persistence displayed in solving the problem.
-- mjes79, 2021-03-08

### ***** "Color is just cheap thrills ....."
Love this app!  Makes duo-tone, tri-tone etc.  great renditions for oil paintings.
-- wyodankw, 2020-12-04

### **--- "Waste of $2"
Almost any free photo or drawing app can do this — usually better. That’s why there is no try before you buy feature.
-- Rye in Nashville, 2020-09-05

### ****- "Update issues"
I like this app a lot, I use it all the time to adjust the values in my paintings. Since the last update however I have lost the ability to export images. When I try to export the app crashes on my iPad. On my iPhone when I try to export the export to photos option just doesn’t come up. 
Please fix. My work around for now is to take a screen shot to save the adjusted image and just crop to the image itself.
-- Denisipetisi, 2020-06-26

### ***** "OMG!!!"
Just got this and haven’t figured it all out yet, but WOW!
-- texana55, 2020-01-14

### *---- "Totally disappointing"
Worked fine on my iPad Air for 30 days. Then one day it would not open. Such a rip off.
-- Lived thru it, 2019-11-01

### ***** "Brilliant simple app!"
Perfect app for breaking down an image into a simplified set of forms. I totally love it. So simple. So brilliant.
-- dbonneville, 2019-01-04
