NotanIzer APP
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 3 level version. Breaks down your image into 3 adjustable levels of brightness.
The fourth is a 4 level version just like the 3 level.
And finally there is the new Levels. Breaks it down into even levels from 3 to 10.
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.
PLEASE NOTE: Make sure there is at least 20mb of memory available on your device as making adjustments can be memory intensive.
