3 Common Lens Corrections Applied in Professional Picture Editing

Photo Editing Services
Lens Correction Techniques

A commonly attributed cause of distortion in images is the type of lens used in the camera. Almost all the photographic lenses tend to suffer from some kind of distortion, which is particularly on the edges that result in slight distortions in the image. Most cameras have an inbuilt feature that gathers the lens data and corrects the distortion. However, this in-camera correction process is not effective and it can only be resolved through professional picture editing.

In photo editing, lens corrections are a crucial aspect carried out in all the images. Although not visible when viewed normally, these lens distortions can affect the appearance of the image as a whole. It is therefore vital to apply lens corrections in the images captured.

Most of the photo editing services utilize the process of lens correction in order to free the images from any kind of distortions. During editing, professional picture editing services focus on three of the common lens corrections, as described below.

Vignette

Vignette is the appearance of dark regions at the corner of an image. This is a common lens distortion caused due to insufficient light falling on the corners. It can affect the appearance of an image as a whole.

Vignetting is of two types, physical and internal. Physical vignetting can be corrected by means of cropping or brightening the specific regions in the image. Internal vignetting, on the other hand, is easily correctable, as it occurs commonly with wide angle and zoom lenses.

Chromatic Aberration

Common Distortion Issues

Chromatic aberration is another common lens distortion in images. It causes the appearance of colored hinges to form especially in high contrast areas of the image. It is a complex lens distortion arising due to various imperfections in the alignment of the lens elements and in some cases, the image sensor itself.

Chromatic aberration can be reduced to a large extent during the image editing process. The various corrections for reducing chromatic aberration can improve the sharpness and quality of the image.

Distortion

Distortions in the image are also common, particularly in any straight lines, which cause the lines to appear bending inwards or outwards. Some of the common types of distortion are perspective distortion, barrel distortion, and pincushion distortion.

Professional picture editing services place great importance on correcting any of these types of distortions. This is because these kinds of distortions are immediately perceivable in an image, thereby affecting its appearance.
