Here are some pinhole images- When you see the cameras I made and used I hope you will understand the problem, I am slowly overcoming, with aiming the right way. Also these were tray processed thus some scratching. Also there is some internal reflection causing lines--all to be worked on except the internal reflection (I have no source for "rare earth glass!)

Actually, that is quite an accomplishment. Very good work.

I don't see the point. Maybe it's a pinhole.
The point?
Experimentation. Learning. Stepping out of your comfort zone. Trying something new.
Yes, it's a pinhole. Funny.

We were taught the technique many years ago in my first photography class. Good job Vertigo.

Classes I taught used single wt. paper (paper base) in the camera (loading and processing with a safe light was soooo much easier) then contact printed the paper negative. Now the paper I have is either double wt. or RC and neither works as well. So onward with film (what I found is end dated in the 70's no less) Hopefully I will get better and have better luck.

Suggestions and questions:
- paint the inside of the camera flat black to avoid internal reflections
- make sure the pinhole is clean
- add a tripod mount to avoid movement during the exposure time
- what is the focal length of a pinhole camera?
- what is the effective aperture (f/stop)?
- paint the inside of the camera flat black to avoid internal reflections
- make sure the pinhole is clean
- add a tripod mount to avoid movement during the exposure time
- what is the focal length of a pinhole camera?
- what is the effective aperture (f/stop)?

Insides are painted black. some pinholes were created just that--a pin hole and others were professionally (no me) drilled in copper sheets. Tripod mounts are hard to do on a cardboard camera. So I agree with all that.
Effective apertures are difficult--depends not only on exact size of the hole but also on the size of the camera. On 8X10 it is two stops smaller than on 4X5--as light is spread over 4 times as much area it takes 4 time the shutter speed. Apertures are somewhere between about f256 and f1000 in my experience. focal length is sort of whatever you want it to be. But they are wide angle--most of mine are taken within about 2 to three feet of the main subject.
Hope that answers most. Just thought--could glue a quick release to bottom of "camera" except it's the devil to lunge anything with todays adhesives. A brick on top of the camera seems to serve well most blur comes from subject movement during the looooong exposures.
Sorry, that got long.

Probably just me, but #2 and #3 strike me as being akin to 50's crime scene photos - not that THAT is a bad thing. :-)

Could be bad! But honestly, no crime committed! They were shot on 4X5 as were many of the crime photos back then!

Have you seen a book "Pinhole Photography", by Eric Renner?
Look for the second addition. From the history(before photography) to all the technical data and numerous examples.
On Ebay under $10.
There are more modern methods, too. Canon, for instance, can be mounted with a laser pinhole in a body cap. Mine was about $10 a few years back. You can easily make your own. Use brass shim stock for pin(needle)hole.
Not too hard to get interesting photos. You may need a tripod for best success.
