A half-tone image represents continuous tones in the image using single tone dots of varying sizes.

Half-tone screens have been important for the printing industry since the late nineteenth century. By allowing gray levels in images to be represented by varying the sizes of black dots, they made photographic printing on industrial scales, such as newspapers, practical.

You can experiment with the size and angle of the half-tone screen. Smaller screen sizes give a higher resolution.

You can change the brightness of the image by increasing or decreasing all the points together.

By changing the screen angle (the angle at which the points are positioned relative to each other, you can change the interference effects between the image and the screen.
