The fisheye effect can be corrected in Photoshop.
The fisheye effect is also known as "barrel distortion" and is a type of image distortion that makes and image look wide and circular, as if looking through the eye of a fish. While some photographers use a fisheye lens to intentionally create this effect, some cameras may exhibit some of the distortion and characteristics of a fisheye lens, especially when taking photos in macro mode, which you may wish to correct using Adobe Photoshop.
Instructions
1. Open Photoshop by clicking its icon on the desktop or in the "Programs" section of your "Start" menu.
2. Click "File" then "Open" and navigate to the image you wish to correct and click "Open."
3. Click "Filter" in the top toolbar, then hover the mouse over "Distort" until a new menu appears. Click "Lens Correction" in the new menu. This will open the "Lens Correction" window.
4. Click the "Settings" menu and try each of the presets in the drop-down menu. If the presets do not give you the results you seek, continue to the next step.
5. Click and drag the slider in the "Remove Distortion" field to remove the fisheye effect from the photo. If the correction caused blank areas to appear at the edges of the image, you can click and drag the "Scale" slider to scale the image and cover the blank areas.
