What effect occurs on costumes or set elements that have high contrast stripes and delicate patterns?

When costumes or set elements feature high contrast stripes and delicate patterns, the Moire effect often occurs when these patterns interact with the camera's sensor or the viewing device. This effect manifests as a wavy or distorted pattern that is not actually present in the scene itself, but arises from the interference between the repetitive patterns of the clothing or set and the grid of pixels in the camera sensor.

As the camera captures the image, the alignment between the patterns and the pixel structure can create unexpected visual artifacts, leading to these wavy or shimmering effects. This is particularly common in situations where patterns are photographed or filmed at certain angles or distances, which can exacerbate the interference.

Understanding the Moire effect is essential in production design and cinematography, as it can detract from the intended aesthetic of a scene. By recognizing the potential for this effect, designers and filmmakers can take steps to avoid or mitigate it, such as altering the design of costumes, using different materials, or adjusting camera settings.
