Drawing Grid vs NotanIzer

Drawing Grid helps artists transfer proportions from a reference image to paper or canvas. Choose a canvas preset or enter a custom physical size. Configure the grid by row and column count or by cell size, add diagonal overlays, and choose the line color, width, and opacity. Image Editing mode keeps image gestures separate from canvas navigation. Move, pinch, rotate, crop, center, fit, fill, reset, or adjust the reference opacity. Canvas Navigation mode is available whenever you want to pan or zoom the workspace. Your complete last-used workspace is saved on-device. Export produces a deliberate 2048-pixel PNG containing the reference and grid without menus, selection borders, indices, or other editor controls. Drawing Grid 3.4 requires iOS or iPadOS 17.0 and supports iPhone, iPad, rotation, Split View, resizable windows, VoiceOver, Dynamic Type, dark mode, Increase Contrast, Reduce Transparency, and Reduce Motion.

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.
