I’m photographing company products with a 15 MP smartphone camera. In one image I notice a rippling or wavy pattern, especially when the photo is viewed smaller than full-screen. What causes this effect?

This is called a Moire pattern and is created by the regular lines of the tiles in the photo interacting with the black grid between the pixels of any computer monitor.

What you’re seeing is most likely a moiré pattern. It happens when fine, repeating detail in the subject—such as the regular lines of the tiles—interacts with another repeating grid, like the pixel structure of a computer display or the resizing of the image for screen viewing. That’s why it can look worse when the image is not shown full size.
In short, the pattern is usually not a mysterious camera fault; it’s an interference effect between repeating patterns in the photo and the way the image is displayed.
