I was looking into what a fish eye lens will do and thought I wouldn't have much use for one but on a few photos it could be neat, so I looked around for some information on whether it could be done in Photoshop or not and it can, so here's the link in case anyone else is interested in it. I tried it and it looks kind of cool on certain photos.

Fish Eye effect using Photoshop

Anyone who commented on this thread in the forum, feel free to add your feedback again in a comment here, especially those with tips on how to make this effect work better (enlarging the canvas size, for example...)
