Ultra wide-angle lenses, such as 12-24 mm zoom lenses or fisheye lenses, are most susceptible to wave distortion due to their wider field of view and unique optical construction. These lenses tend to exhibit more pronounced wide-angle distortion towards the edges of the image plane, especially when shooting at close distances.

In architecture, landscape, and product photography, where straight lines, geometric shapes, and level horizons are essential to the composition, even small amounts of lens distortion are unacceptable.

In both barrel and pincushion distortion, the effects are most apparent near the edges of the frame. At the center of the image, the distortion may be so slight as to be unobjectionable.

You’ve probably experienced lens distortion in your images in one form or another. If you snapped a photo of a building and edges that should be straight lines appear curved or distorted, that’s it.

Lenses with longer focal lengths are most susceptible to pincushion distortion. For example, telephoto lenses of 200 mm or more tend to squeeze the image, leading to the bending of straight lines towards the center.

In their long tubes, telescopes house lenses with powerful magnification properties that allow scientists and space enthusiasts here on Earth to see distant planets, galaxies, and objects floating millions of light years away from us.

The quality of the glass used, the precision of manufacturing, and the overall construction and optical design of the lens impact the level of distortion present in photos. Prime lenses with focal lengths in the range of 50mm to 85mm are generally the least susceptible to this type of distortion. A lens with a focal length in this range has a more natural field of view that closely resembles that of the human eye. Very often, these types of lenses are preferred by photographers who specialize in portraiture and architecture, where distortion is a major concern.

The options in the Manual tab give you an effective way to address lens distortion. Please note that even though it’s a more cumbersome process than using the built-in profile, you have greater control of the outcome.

Now that we understand the various forms of lens distortion, what can we do? This distortion appears as distorted or curved lives. It is most obvious and objectionable in genres of photography that require precise and accurate representation of subjects.

Other genres, such as macro-photography, portrait, and wildlife, the absence of straight lines makes lens distortion difficult to detect. In these instances, lens distortion may be present, but not objectionable. That is, the emphasis is on the overall composition and mood of the picture rather than accuracy of horizontal and vertical lines.

This type of geometric distortion results in straight lines that bend inward towards the center of the image. Pincushion distortion gives the image a compressed look.

A combination of barrel and pincushion distortion, wave distortion causes the lines to curve away from the center near the top edge and bottom edge and dip upward at the sides. The effect resembles a wave or a mustache shape.

In these situations, corrective lenses - either in the form of glasses or contact lenses - are added on top of the eye to help properly focus and represent images of things around you.

To correct lens distortion in post-processing, photographers utilize software tools with built-in lens profiles to reduce or eliminate the distortion. Sometimes, we find a creative use for it, turning a negative into a positive.

Adobe Lightroom contains built-in profiles for thousands of lenses. These profiles are calculated to correct most types of lens distortion. And stop me if you’ve heard this before: you’ll get the best results working with RAW files.

When light passes through the elements of a lens, the varying shapes and angles lead to geometric distortions in the final image. This distortion manifests in different ways, depending on the curvature of the lens elements. The distortion results from how light is refracted and focused onto the camera sensor. And for the most part, this distortion increases towards the edges of the frame. The center of the image will have the least amount of distortion.

Lens compression is the visual effect that occurs when using telephoto lenses, making distant objects appear closer than they actually are.

This complex form of geometric distortion can be difficult to fix and may require specialized processing software. Note however, that trying to correct distortion of this type as if it were the barrel or pincushion variety could make the distortions even more objectionable.

The image below illustrates this type of distortion. The combination of a low angle, the camera close to the subject, and an 18-mm lens makes the front fender appear abnormally large. Meanwhile, the side of the car seems small and out of proportion, especially toward the rear.

Both an unwanted artifact and a creative technique, lens flare occurs when light enters the lens, reflects, and scatters. The resulting bright spots or streaks may distract from the main subject. However, photographers often embrace lens flare as a creative element.

Without the invention of the telescope, our knowledge of space would be limited to the stars and structures, such as the moon, that can be seen with the naked eye.

A telephoto lens compresses the image and makes the subject appear thinner. This may give you a positive outcome for some portraits. A wide angle lens exaggerates features, especially at the image center and at a close distance to the subject.

In most cases, lens distortion is a negative. It is most objectionable in architectural photography, for example, where straight lines and angles are crucial for capturing buildings and structures accurately. Additionally, landscape photography can also be affected, as the distortion can alter the natural shapes and distort the horizon.

MagnifyingGrass

The lens is used to magnify small objects such as insects or individual leaves on plants so that the viewer can better see them and the details on them. The amount of magnification depends on the power of the lens used, as well as the distance between the lens and the object.

Lens distortion in photography refers to aberrations in optical systems that result in the warping or bending of images. It can have a significant impact on the quality and accuracy of a photograph, distorting the subject and creating an out-of-proportion look. Powerful image processing software is available to correct the most common forms of lens distortion.

Essentially, a microscope is a series of magnifying glasses housed in a tube. Because there are more lenses, and the lenses have varied magnifying power, microscopes can show an incredible amount of detail.

This is common, but most objectionable in certain genres of photography such as architecture. Also, it is more pronounced in some lenses than others. There are several variations of lens distortion. Examples include barrel distortion, pincushion distortion, and mustache distortion, aka wave distortion. In addition, chromatic aberration and perspective distortion should be included.

All the lenses inside the camera have to work together to focus on the image to create the clearest, most true representation of whatever you’re taking a picture of, or else you end up with a blurry photo. When the lenses work together properly, you get a sharp, clear photo to help you remember a moment.

This type of image distortion causes straight lines to appear curved outward towards the edges and corners of the image. Its shape is similar to a barrel. This effect can be quite noticeable, especially in images with a lot of straight lines or geometric shapes.

A magnifying glass is nothing more than a large convex lens held in a frame. It’s possibly the simplest application of a lens in common use.

Depending on how poor your vision is, you may need lenses of a higher power to help you drive, read, and cook without too much difficulty. And, if your eyes need different lens powers to focus on objects that are far away and those that are up close, corrective lenses can be made into bifocals and trifocals allowing you to switch between magnifying powers without having multiple pairs of corrective lenses.

The aperture is an opening that lets light into the camera. The lenses are then moved back and forth to help the camera focus on the image you’re trying to capture, then the final image is captured when you press the shutter button.

A common optical issue, chromatic aberration occurs when different colors of light are not focused at the same point on the camera sensor. This results in colored fringes appearing along the edge of objects in an image, particularly noticeable in high-contrast areas. These aberrations are common to some degree in most lenses, more so in zoom lenses that have more elements and moving parts than in prime lenses.

While microscopes magnify tiny things that are fairly near, telescopes use the same system of lenses to show us large structures that are very far away.

Transform is especially useful when photographing buildings. In the two examples below, the first photo exhibits a backward lean. The second photo shows the corrected perspective rendered by Lightroom. The difference is substantial. And, as you can see, it’s a good idea to leave plenty of room to crop after the perspective change.

If Lightroom doesn’t have your lens profile or if you want full control for correcting lens distortion, choose the Manual mode on the Lens Corrections panel. Move the Distortion slider to the left or right to remedy barrel distortion or pincushion distortion.

When the camera is very close to the subject, we get a distorted or skewed appearance. A wide-angle lens exaggerates the effect of this distortion. Adjusting the angle and position of the camera and lens may reduce the impact of perspective distortion.

Usually, we aim to minimize it, but lens distortion offers creative opportunities. Photographers explore and experiment with the visual effects, normally called defects of the optical systems, to add a creative touch to their images.

Read this article carefully to gain an understanding of the various lens distortions. A priority for photographers is image quality. Be aware of the different types of lens distortion, then anticipate and minimize the effects in-camera or correct them in post-processing. Or in some situations, you may want to use lens distortion as a creative effect.

Lens vignetting is a gradual darkening of an image at the edges; it is often an issue to be corrected but sometimes used as a creative touch.

After the image is imported, go to the Develop module and locate the Lens Corrections panel. Select the Profile tab and check the Enable Profile Corrections box. Based on the metadata in the image file, Lightroom detects the lens used to capture the photo and applies the appropriate action to correct image distortion. Also, you can check the Remove Chromatic Aberration box.

If you’re looking to see the tiny details on something really small, for example, you will need to get a magnifying glass that has a higher-powered lens and ensure you’re holding it close enough to the subject to see those details.

Barrel distortion is most commonly seen in wide-angle lenses, particularly those with a focal length of 35mm or less. Lenses with a wider field of view exaggerate the distortion effect.
