Create a fish eye lens effect in Photoshop

Fish Eye Lens

First, make your selection of your fish eye view with the Elleptical Marquee Tool (M). Hold down the "Shift" key while selecting, so that you'll keep the circle perfectly round. The selection is the most important part to get a good Fish-eye effect. Most of the distortion will be at the edges and lots of emphasis on the center, so anchor the middle with something interesting.

Inverse your selection by going to Select > Inverse (Shift+Ctrl+I). Now press "Delete". Now you've narrowed down your image to your Fish-eye lens. Reverse your selection (Shift+Ctrl+I) to get your selection back to the Fish-eye lens.

While still selected, Crop the image by going to Image > Crop. With this done, you should only have your Fish-eye lens as your image.

The Fish-eye view is one of the standard filters in Photoshop. With your selection still on, go to Filter > Distort > Spherize. This will bring out a pop-up window with the spherize settings. Set the amount to 100% and the Mode to Normal. Now press "OK" and let Photoshop do his thing.
