Sometimes I take photos of my computer monitor with a smartphone. Then, when I try to zoom in to the picture of the monitor in the gallery of my phone, I start to see this pattern.
I am not sure if this is really just moire pattern. I mean, after I have taken the picture, I go to the gallery, look at the picture and change the zoom. As I start to change the zoom, I start to see random contouring pattern changing rapidly and changing shape, they look like something like below.
Can someone explain why?
