Aliasing in photography shows up almost exclusively where highly intricate patterns involving tight, repeating sets of lines, concentric circles, small angles, or grids appear. For this reason, it’s rarely an issue for landscape or nature photography. Architecture photographers or fashion photographers, however, need to keep an eye out when buildings or fabrics have a pattern or texture. Clothing with a checked or striped pattern is a predictable aliasing suspect. You might also notice it when photographing door or window screens or the screens of digital devices. Aliasing can be more common when using lower-resolution cameras or standing further from a subject, but with the wrong combination of patterns or angles, it can show up in even the most high-resolution photos.
“I did architectural photography for a while, and I would encounter it every now and again on a roof or the side of the building,” says photography professor Adam Long.
