Why does taking a picture of a monitor look weird?
The strange pattern you see in digital images of screens is what happens when two grids interact. When you take a picture of a screen, the camera’s grid won’t be able to accurately represent the screen’s grid unless they’re aligned exactly.

Ways to Get rid of the Moiré Effect
- Change the camera angle: Changing the angle of the camera itself will adjust the way the 2 contrasting patterns overlap.
- Change the camera focal length: Changing the focus of the camera will adjust the resolution of the photo, thus changing the overlay patterns.
Why does moire effect occur?
Moiré pattern occurs when a scene or an object that is being photographed contains fine, repetitive details that exceed sensor resolution. As a result, the camera produces strange-looking wavy patterns.
How does the moire effect work?
Moiré effect is a visual perception that occurs when viewing a set of lines or dots that is superimposed on another set of lines or dots, where the sets differ in relative size, angle, or spacing. The moiré effect can be seen when looking through ordinary window screens at another screen or background.
What causes moire effect?
This effect is called moiré and is caused when a fine pattern in the subject (such as the weave in a fabric or very close, parallel lines in architecture) matches the pattern of the imaging chip. In order to reduce (or eliminate) moiré, a special anti-aliasing filter is mounted in the camera.

Tips for Using a Phone to Photograph a Screen
- Source Adjust your phone’s camera settings if you are able. Ideally, you should control the shutter speed, setting it to about 1/30 second.
- Do not zoom in to frame the shot.
- Find a hard surface for your phone.
- Use your phone’s self timer for the shot.
What causes moire patterns?
What causes moire in photography? Moiré pattern occurs when a scene or an object that is being photographed contains fine, repetitive details that exceed sensor resolution. As a result, the camera produces strange-looking wavy patterns.
How do I stop moiré?
Change your distance to the subject or adjust your focal length. Often the best way to get rid of moiré is to change the distance between your sensor and the subject. That either means getting physically closer or further away or, if you’re using a zoom lens, changing your focal length by zooming in or out.
