Picture of $11 Super Wide Angle Digital Camera
Add a 160 degree wide angle lens to your existing digital camera for $11. This was based on ideas from the following webpage: http://aggregate.org/DIT/peepfish/

Step 1: Go to your favorite hardware store, and buy a wide angle door viewer.

Picture of Go to your favorite hardware store, and buy a wide angle door viewer.
You should be able to find one of these at any hardware store. I got mine at Home Depot for about $11. The key attributes that you're looking for is the largest possible "eye hole". There are a bunch of these door viewers that have very small openings, and they won't produce a very good image. Get the one I'm showing here, and it will work great. The opening is just about the size of the lens on my old Canon S230.

I tried this over the weekend. It works great. I used the idea on my 300D SLR.
As there was a lot of bright lights I got a ton of flaring. Check out some of the pictures below.

There are good SLR instructions here. Short version below:

I had drilled a hole in a 55mm lens cap ($4.95)
I used the same peephole from homedepot and hot glued it to the lens cap. ($7.50 and $1)
I attached the lenscap to my 28-90 Sigma lens (it has macro)
Pictures where best around 50-70 mm not in macro mode and with manual focus

This was my first instructable project!
Nice work mate ;)
I went to your link - these speak to me also! They are really cool - use them for the art work on CD's - you can buy round labels for them, glossy is best. Wonderful!
Hey good job.

In the OLD days, we would find an extra lens cap and cut a hole in the center big enough to hold the door viewer. Just snap it on and you're good to go.

I also tried this with a point and shoot but epoxied another lens on top, a lens I got out of a cheap "panoramic camera", just epoxied the edges and got a nice effect. Will post pix soon.

The large door viewer seems the way to go with these projects.

thanks for this instructable man, i knnew that saving this door "eye" would help me someday, and now i did. you should add to the key words of this intstructable "skate" because this is how sk8 videos are shot and that was what i was looking for.

You know, if you measure out the DoF properly, you won't need to crop this bit out.
you should use some kinda tube, and maybe some tape, without using the sticky side on your cam. to make it removable.

iv got this yes video camera its a mini camera wat do i no and i want one for my skating
I found your project a couple weeks ago, linking off a DIY kaleidoscope lens project. Most of the time I work with a full-size camera, and had never really thought of using a door viewer with the lens on a small camera. I gave your project a try with a cheap point & shoot I have, and the results were impressive. I then figured out a way of using a piece of plumbing hardware to adapt the viewer to my bridge camera, which doesn't do too bad of a job of making fish-eye pictures. Good work!

If you could find a 180 degree door viewer you would have a fish eye lens
At Home Depot they have 200° viers right next to the 160° ones. I got one and will post pictures soon.

That's pretty sweet. Is there a way you could make them the regular rectangle photo shape, instead of the circle, or would that be too hard to do in-camera with this rig?

Lovely pictures! Your cats are so cute! The coloring on one looks like split bangs and the other one seems to have an eye patch-this will be fun to play with. Thanks!

Used Nero PhotoSnap to correct the distortion as shown. Takes away some of the charm ? :)
Could you tell me how to do that? I know how to do the thing where you take a picture of a flat surface at an angle, the use the proportion/crop function and it looks straight, but how would you do that with this?
its a wide angle or a fish eye lense you can get them for all kinds of cameras it makes the shot wider
I know that, but can you use Photoshop to take the round, wide-angle pictures and turn them into normal square ones (like shown above)?
definitley the first looks so much cooler whats the point of a wide angle lenseif theres no hokey ring of distortion?

The reason this doesn't look as interesting as you might expect is that all the objects in frame are too far from the camera. Take a skew-angle close-up picture and correct that. I think you'll get a much better feel for how weird things get. BTW, if the purpose of PhotoSnap is to stitch panoramas, then you'd expect it to look "normal" wouldn't you?

If you remove the barrel on the fisheye, (hacksaw) you no longer have to worry about the "tunnel vision"
