There are a few ways to remove moire pattern in Photoshop. The first way is to use the Clone Stamp tool. The Clone Stamp tool is a great way to create copies of an object and then paste them into different positions. You can also use the Selection tool to select a part of an image and then use the marquee tool to select all of the surrounding pixels. The next way to remove moire pattern is to use the Filter > Blur > Gaussian Blur filter. This filter will blur all of the pixels in an image, making it difficult to see any moire pattern.
