Perspective distortion is particularly noticeable in portraits taken with wide-angle lenses at short camera-to-subject distances. At this distance, each of my facial features is a similar distance from the camera - within a few percent of the total distance - so my face appears flat Paskhover and colleagues explain in JAMA Facial Plastic Surgery that the distortion happens in selfies because the face is such a short distance from the camera lens. In the leftmost image, the subject is far away (2 metres) from the camera. Actually, the only 'distortions' are caused by geometry, they are nothing to do with the lens or the camera. The lens on your camera can affect how you appear in photos. The closer something within our field of view gets to our faces the larger it appears in relation to the objects behind it, and the inverse of that is also true Perspective distortion deals with your proximity to the subject and relative to surroundings. At the very base level of all of this is the matter of lens and perspective distortion.It is the distance from the camera to the subject that plays a critical role in the level of distortion This is very misleading at face value because portraits range from head shots to environmental shots. There is the accepted rule in the photographic community that portraits cannot be shot with wider angle lenses.g of the first, the face will look exactly the same in both photos.A face taken with a 50 mm and a 300 mm lens would appear exactly the same - if they were taken from the same distance From like 30 mm upwards lenses have very low distorsion.Even standard 50mm prime lenses can potentially yield barrel distortion at close distances

The amount of distortion can vary, depending on camera to subject distance.

Barrel distortion is typically present on most wide angle prime lenses and many zoom lenses with relatively short focal lengths.

Barrel distortion is where straight lines bend outward from the center of the image Does Focal Length Distort Subjects The two most common types of lens distortion are barrel distortion and pincushion distortion. Many photographers claim that a wider angle lens will distort facial features either because of the lens distortion, or the focal length of the lens being too short In a nutshell, it's when a lens produces curved lines where straight lines should be.

Additionally, any nasal asymmetry maybe exaggerated due to stretching One of the common misunderstandings in photography has to do with the focal length of a lens, or its optical distortion properties.

This facial widening distortion also causes the ears to disappear on the photographs. Taking face photos with short lens cameras and up close results in the whole face, nose, and eyes appearing wider and face and nose longer than in real life. You may not be concerned about selfies and how your own nose looks, but if you're a portrait photographer, you ought to be concerned with how your subject looks and your lens selection can certainly play a role in how a person's face appears in a photo.Home Camera lens distortion face Phone cameras / selfies distort the face making the face That's a significant increase and it brings up an interesting discussion on how different lenses can capture a person's facial proportions and overall appearance very differently. The same phenomenon behind selfies making your nose look bigger can also help explain why wide angle lenses are typically not a great choice for capturing portraits of other people.įrom 2016 to 2017, the percentage of people who came into a plastic surgeon's office seeking help for looking better in selfies went up from 42 percent to 55 percent. While "selfies" may not be the most common use of cameras for those of you reading Imaging Resource, it's nonetheless the case that a new video by Vox about why selfies can make your nose look bigger intersects with camera technology.
