Would then a thick material create a smaller circle with the same image
quality (or not) as a thinner material? These may be simple questions but I
want to be able to control the size of my image circle, either through
pinhole size or focal length. It now sounds like material thickness could be
a
The rule of thumb is that, on a flat film plane, the circle will be
3.5 times the focal length. So, if the focal length is 1 the circle
will be 3.5, if the focal length is 2 the circle will be 7, and so
on. The f-stop doesn't really matter for this rule of thumb.

Jim, your link broke down, this happens to me all the time. I have found this
site in which you paste a long link
Here's a good resource with lots of links... I found it by
putting pinhole astrophotography into a search engine

I apologize for being slighty off topic. I'm not a pinhole photographer, but
I'm working on a science-fiction story that involves pinhole astronomy. I'm
looking for good sources of information for the novice that explain the theory
of pinhole cameras or telescopes. I don't mind getting into the
Hi All,
I made my 24x30 cm pinhole camera with a pinhole of 0.35 mm pierced in a
coke can foil.
Amazing results, and these are my first attemps.
The only remaining problem that I would like to solve is the following:
When taking a picture against the sun, I have sharp reflections on the
pinhole
There's a yahoo group DigitalBlackAndWhitethePrint that covers using quadtone
and hextone inks in exhaustive detail.

Hi,
Here is some context:
Iris printers started in the early 90s and they are high quality 4 color
inkjet devices.
For the length of exposure that a pinhole needs, you don't need anything
complicated.
You could make a lightproof cap that fits the front of the camera and just
take it off for the exposure!
