Avoiding Moire Patterns On iPhone Screen

[Daniel Soderberg]

Anyone have any tips on avoiding unwanted moire patterns when recording an iphone screen?
Thanks!

Moire is interaction between the pixel grids of the camera sensor and the iphone screen. You can put a softening camera filter in, or a diffusing film on the iphone, zoom in or out to minimise moire, move closer or further away to minimise moire, defocus the lens slightly, or replace the screen in postproduction. Having both camera and iphone locked off also helps any moire be less distracting as the pattern will be stationary at least.

Thanks Eric.

screen replacement or putting the lens slightly out of focus will probably be your best bet. Also if you are shooting RED make sure you look at the footage in post, dont' rely on the down scale video out, that will not show you the same moire effect as the recoded footage. Having camera and screen locked off as suggested above will really help as well.

Sometimes pulling a defocus key on the display (the iPhone screen in this case) can help. Defocusing only the vertical or only the horizontal, in very small increments, can get rid of most of the moire.

The best solution is to replace the screen with VFX, so that then you have 100% control on it later on in post.

Anyone know a good softening filter that has worked for them to minimize moire on the iPhone?
Making things a bit off focus won't always work if the phone or camera moves.

Thanks,
