This one is a classic. A camera with no lens. Just a (really small) hole in an otherwise opaque material. Here is my own experiment, took me about 2 minutes total to prep it

So, your task is to achieve a similar (and hopefully, much more better quality) goal. What do you need to know is:
Multiple focal lengths are encouraged. So are special effects (hole off center, non round whole, multiple wholes, crater refraction, etc.)
Let's get pinholed!

So, your task is to achieve a similar (and hopefully, much more better quality) goal. What do you need to know is:
- Put a lot of attention to the mount quality to avoid the stray light.
I found out the kenko tubes work the best as a base, but just being carefull would work... - To get the sharpest pictures you need the smallest hole. Like, seriously small. Like a human hair small. Start with a pin and see if you can get it smaller by adjusting the size
- The hole border quality (i.e. "crater walls") can bring some interesting effects, play with it
- You can actually have longer focal length but moving your "hole" away from the camera. Again, kenko tubes work great in that respect. Just remember: the longer away your whole, the "slower" your "lens" is.
- Especially with a longer focal length, a tripod, MLU (or liveview) mode and a remote release may become necessary to obtain highest quality pictures.
Multiple focal lengths are encouraged. So are special effects (hole off center, non round whole, multiple wholes, crater refraction, etc.)
