Editing Parallax (section)

== Photography ==
Parallax error can be seen when taking photos with many types of cameras, such as [[twin-lens reflex camera]]s and those including [[viewfinder]]s (such as [[rangefinder camera]]s). In such cameras, the eye sees the subject through different optics (the viewfinder, or a second lens) than the one through which the photo is taken. As the viewfinder is often found above the lens of the camera, photos with parallax error are often slightly lower than intended, the classic example being the image of a person with their head cropped off. This problem is addressed in [[single-lens reflex camera]]s, in which the viewfinder sees through the same lens through which the photo is taken (with the aid of a movable mirror), thus avoiding parallax error.

Parallax is also an issue in [[image stitching]], such as for panoramas.
