Um...I made a pinhole...

I have a problem with shake, though, on the tripod, due to it not being a body that I can use a cable release with. The wind didn't help either. I'm debating whether or not to put this rig on the front of the Canon P using something...it may be fun to actually take with certain places. The pinhole is made with a screwdriver (strange, I know) in a piece of electrical tape (even stranger). Whatever works I say.

Pay no attention to the drying mark. I wanted to get them scanned so badly that I blowdried them and didn't bother with my usual wash in distilled water.

a screwdriver - are you sure the hole isn't too big? that could cause unsharpness as well. I used the thinnest needle I could find and I got pretty sharp results using a shoebox and some photo paper.
 
Why are you making the pinhole in tape? An easy alternative with a bit more sturdiness is a chunk of an aluminum can.

A screwdriver hole will be WAY too big.

I've read that aluminum foil is a good medium to accept a pinhole.

The simplest way of making a pinhole camera is just to drill a hole in the center of a camera body cap, tape aluminum foil over the hole, and prick it with a pin. If the metering of the camera is sensitive enough, it will time the exposure for you.
 
The smaller the hole, the finer the detail it is capable of rendering.

Too small though and something called diffraction degrades the image.
 
I kinda like the blurry feel to these. It's kind of interesting, really. I would, however, like to try and get a bit more sharpness...but not TOO much.
 
I like it!

Anyway, thick aluminum foil is better. And a needle is better to make the hole with. Now where is my pinhole photography book.... saw it clearing out the basement. Found a cool 4x5 oscilloscope camera, put it in "The Box"...
 
my first pinhole camera wa made with a Nestle Quick can...I wish I still had it...I like it Steph, though only if you say it's a pinhole, otherwise it's just a fuzzy neg :p
 
I'm going to try again with a pin to see if I can get anything better. Then I'll take a photo with it inside...somewhere. It'll take a longer exposure, though. Blah.
 
If you use extension tubes (slr gear) between the bodycap/pinhole and the camera, you will increase the focal length of the "lens". The distance between the film and the "lens" is the focal length.
