Moiré pattern occurs when a scene or an object that is being photographed contains repetitive details (such as lines, dots, etc) that exceed sensor resolution. As a result, the camera produces strange-looking wavy patterns, similar to the ones below: See the strange rainbow pattern on the left side of the image, as well … See more In photography, moiré happens when the item being photographed contains a detailed pattern that does not play along with the pattern of the imaging sensor. With two separate … See more For many years, camera manufacturers have been dealing with moiré patterns by introducing a “blur” filter in the optical low-pass filter (which is a filter stack that sits in front of the image … See more Unfortunately, removing the moiré pattern in non-destructive editing application like Lightroom, is sometimes impossible, but you can still reduce it quite a bit, especially when dealing with mild cases.

WebTo let other people know, the best way to capture CRTs, SD or PC CRT, is to counteract the effects with an OLPF (opt low-pass filter). Why? The sensor in the camera and the mask/grille in the monitor face are never going to be truly lined up, creating a constant moire, especially if you aren't fixed on a tripod.
