If the subject of a photograph resembles the curvilinear shape of a fish eye, the culprit is a wide-angle camera lens. Dramatic image distortions add personality to a common subject. However, when your subject can thrive free from special effects, a lens correction may be called for. "Fish eye" correction enhances the look of architectural images--and gives them a polished appearance--because unnecessary distortions often look like something an inexperienced amateur photographer would do. Photoshop has a built-in remedy to fix the image whenever a subtle hint of radial distortion interferes with a subject’s natural appeal.
Things You'll Need
- Adobe Photoshop CS 2 or higher
Open the photograph in Photoshop CS2 or higher.
Save the photograph in need of distortion correction by a new name. This step prevents loss of the original image if a mistake happens.
Navigate to “Filter,” “Distort,” and “Lens Correction.” A dialog box will appear.
Check the “Grid” box option. Go to the “Remove Distortion” slider and move it to the right. Stop when the vertical lines within in your photograph align with the vertical lines of the grid.
Address the altered edge area of the adjusted image. The “Edge” selection defines when Photoshop will re-render the background, fill it with color or leave it transparent. The best option is to select "Transparent" and use the crop tool later.
Pick “Save Settings” from the fly-out menu. Give the settings a useful name and click "OK" to make the changes.
Check the image for quality. Blurry edges may be unacceptable. If you are unsatisfied with the results, try the process again or consider other fish eye correction tools. A variety of PhotoShop plug-ins can correct image distortions.
Tips & Warnings
- The ideal images for fish eye correction are those with minimal amounts of barrel distortion. Correction of extremely distorted images can lead to a drop in image quality—especially at the edges of the image.
- Work with a copy of the original image to preserve the integrity of the original photograph.
