Aliasing can also cause problems in digital imaging. In images, the repetition is in space rather than time. A Moiré pattern is an interference pattern produced by overlaying similar but slightly offset templates.

JPEG artifact sare caused by compression when an image is saved in the . jpg format. Each time an image is saved in this format it is compressed and “non-essential” data is discarded.

In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image. It is a form of optical aberration.

Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2.

A full-frame camera is a camera with a full-frame sensor. This is an image sensor that's the same size as the sensor of an analog camera. The biggest advantage of a full-frame camera is that it has no crop factor. Crop factor means that the image is cut out because the sensor is too small to capture the entire image.

“Crop factor” is the ratio of the sensor size to 35mm / full-frame (see below). You take the provided crop factor number, multiply it with the focal length of the lens and you get the equivalent focal length relative to 35mm film / full-frame.
