This effect causes the image to spherize, which means that the edges of the photo look curved and bowed to the human eye. It almost appears as though the photo image has been wrapped around a curved surface.

Fixing lens barrel distortion isn't as tricky as it sounds as long as you follow some of the steps here. There may be times where you don't want to fix it, so embrace the distortion!

Wide-angle lenses include more pieces of glass that are curved so the portions of the image that are at the edges of the frame can become skewed and will reflect this curvature.

While this effect can be appealing in some cases—such as with the artistic photograph—there are many times that you will want to avoid it and have nice, straight lines. This is particularly true when documenting a building: You need the lines of the architecture to be as straight as they are in real life.

Some lenses, such as fisheye lenses, attempt to take advantage of lens barrel distortion by creating a purposefully curved photo. It's a stunning effect when used for the right purpose and with the right type of subject.

When you can't avoid it, go with it, and maximize the effect. The curvature of the lines can be enhanced to create a dynamic look in your photograph.

Pincushion distortion is the opposite of barrel lens distortion. Instead of rounded lines toward the edges of an image, there's a pinch effect in the center of the image. To modify the pincushion distortion, use the Lens Correction filter in Adobe Photoshop or Lightroom. Pincushion distortion occurs most often with telephoto lenses.

Barrel lens distortion is most visible in images that have straight lines in them, as these lines appear to bow and curve.

With the Lens Correction filter in Adobe Photoshop, you can fix image distortion automatically or manually. Automatic correction uses a default camera profile, while manual correction requires you to enter your specific camera settings. A similar Lens Correction tool is available in Adobe Lightroom.

Barrel lens distortion occurs because the magnification of the image decreases the farther the object is from the optical axis of the lens.

Barrel distortion can be corrected very easily in modern image editing programs such as Adobe Photoshop, which contains a lens distortion correction filter. Many free photo editing programs also include solutions to the problem.

As distortion is caused by the effects of perspective on the lens, the only way to correct for barrel lens distortion in-camera is to use a special "tilt and shift" lens, which is designed for architectural purposes. However, these lenses are costly, and only really make sense if you specialize in this field.

Some fisheye lenses are so extreme that the photography ends up being circular in shape, rather than the traditional rectangular shape that's far more common.

Have you ever taken a photograph where the straight lines bow out and become curved at the edge of the frame? Then you need to learn how to fix lens barrel distortion in photography, which is a common issue that appears when using a wide-angle lens.

Whether you want to build your own home theater or just learn more about TVs, displays, projectors, and more, we've got you covered.

If you can't prevent barrel lens distortion with a special lens or prefer avoiding editing after the fact, you can try to minimize the impact of barrel lens distortion while taking photos.
