Have you ever tried taking a photo of your screen only to have the image come out with rainbow lines? These patterns are moiré patterns. It is a visual effect that occurs when the fine pattern of your subject mesh of one image interferes with the pixel pattern on our camera or screens. While sometimes it is a nuisance, this experiment explores the wonder of moiré patterns.
They are present in everyday life.
They commonly occur when you take a picture of a digital screen.
On your screen, some thumbnails show dense markings.
But at actual size, the lines disappear.
Screen as analogue feedback
In this , I used Vionnet’s photographing the screen method harnesses the moiré patterns to contribute to the gradual disintegration of the image. In this instance, I positioned the camera from the screen in a way to maximise the presence of lines.
Screen as composite
The images outcomes of this physically demonstrate the patterning effects. By overlapping the glass panes, the fine lines on one surface interfere with the grid of tiny dots on the other. The distance between the camera and the screen, as well as the angle, impacts the interference between the lines, which led to different colours and patterns.
When we think of the two glass panes as a screen and an image, we can see the same patterning effects, just happening on a screen. Enlarging and manipulating the size of suitable images on the screen have intense effects.
