How can I make a picture have a fish eye lens effect with a digital camera?

The only way really is with a fish eye lense, we use them all the time for panoramic virtual tours, the lense is about $600 USD or so, and they will fit digital cameras, depending on the software you have, there are many things you can do with the image afterwards.

does your cam have that feature???

I have to do the fish eye thing on my photobucket!!!

I have a Fuji S5000 that you can put different lenses on but if you have a fish eye lense you can experiment and put if in front of your camera and see if it has the effect. I used to put binoculars in front of my digital camera and hold it up to my microscope and it takes great pictures that way. You have to hold it pretty still but this is on my small pocket digital 3x zoom. I put the camera in macro mode for my microscope pictures. Most of those fish eye lenses cost more than alot of basic digital cameras.

Depends on what type of camera/lens you have. Easiest (cheapest) way is to go to Home Depot or other hardware store and buy one of those peepholes for doors.

Use a Fish Eye lens.

What do you call a fish with no eye?
