You’ll often notice perspective distortion when photographing buildings. For instance, compression helps smooth out backgrounds (which in turn enhances the subject). See how your nose looks huge in relation to the rest of your face? Compression distortionĬompression distortion is the opposite of extension distortion, and it’s when objects far from the camera appear unnaturally small (or close together).Ĭompression distortion is often referred to as compression due to focal length, but this is incorrect telephoto focal lengths do tend to exhibit more obvious compression distortion, but only because telephoto photography is generally done at a distance.Ĭompression comes with several pleasing effects, so certain photographers, such as portrait, wildlife, and bird snappers, deliberately try to produce it. To see extension distortion in action, grab a wide-angle setup (your smartphone will work just fine!), then put your nose close to the lens and take a photo. However, it is not directly caused by wide-angle lenses, and you can still get extension distortion when using telephoto lenses. This effect is especially noticeable when using wide-angle lenses, as wide-angle photography often takes place close to the camera. Here are the two key types to be aware of: Extension distortionĮxtension distortion, also called wide-angle distortion, is when objects close to the camera appear unnaturally large (or far apart). The 2 main types of perspective distortionĪs I discussed above, perspective distortion isn’t technically lens distortion instead, it’s caused by the distance between the subject and the camera/lens.
Then move the Main and Edge sliders until you’re happy with the result. Once you open your photo in GIMP, select Filters>Distortion>Lens Distortion. If you’re editing a RAW file, you’ll also have the option to use the Auto Distortion Corrections tool. Open the Optics panel, then use the Lens Distortion slider to deal with any distortion issues.

In Luminar AI, head to the Edit panel and scroll until you reach the Professional section. To fix optical lens distortion, click the Geometric Distortion option.Īnd if Photoshop doesn’t recognize the lens or you want to correct distortion manually, go ahead and use the Custom tab. Here, you’ll find plenty of tools under Auto-Correction. If you prefer to correct distortion in Photoshop, however (or you’re editing a JPEG file), then open the Filter menu and click on the Lens Correction option. If you try to open a RAW file in Photoshop, it will automatically pop up in Adobe Camera Raw here, the interface is practically identical to Lightroom, so you can follow the instructions I’ve given above. You’ve probably identified perspective distortion in your own photos, even if you didn’t know what to call it it can get pretty obvious, especially in wide-angle, telephoto, and cityscape photography.įor example, have you ever taken a group selfie and noticed how the person closest to the camera (generally the one holding the phone) looks wider? Or have you ever taken a shot of a tall building and noticed how the building appears to get narrower and narrower as it extends up toward the sky (to the point that it seems like it might fall backward)?īoth of those effects – as well as many others – are caused by perspective distortion. Instead, perspective distortion is created by the position of the camera in relation to the subject. Perspective distortion, on the other hand, technically isn’t lens distortion (though it often gets labeled as such). Interestingly, some zoom lenses actually produce multiple types of distortion depending on which focal lengths you test.
The focal length, the design, the number of glass elements, and other factors together determine the amount and type of optical distortion a lens will produce – so some lenses feature significant distortion, while others are completely (or nearly) distortion-free. Note that a lens can be plagued by three kinds of optical distortion, which I explore in greater depth below: Optical distortion is caused by the construction of your lens. There are several broad types of distortion, but the two most common are optical and perspective distortion: Optical vs perspective distortion Or a building’s sides might compress as they extend upward. For example, a flat subject might appear to bow outward.
