Moire is a pattern of light or dark lines in an image. It is caused by subjects that have repeating patterns like fences, bricks, clothes, or any other subject with close parallel lines that match the pattern of the image sensor in the camera.
Although this is a normal phenomena, the guidelines below are methods that can be used to reduce and avoid it.
- Change the recording angle.
- Change the distance to the subject.
- If possible, try adjusting the focal length of the lens.
- Select a different focus area.
- If possible, try using a smaller aperture like F11, F16, or F22.
