History of the pinhole camera:
Gambattista della Porta In 1593, Gambattista della Porta (1535-1615) described a process for faithfully reproducing engravings in his book Natural Magic. The apparatus used is a pinhole camera or camera obscura, which in Latin means "dark room."

The Mona Lisa Pinhole-Zoneplate Field Camera, designed and built by the Renners at pinholeresource.com, shown here as it appears both opened and closed. This came out in 2003, and disappeared from their offerings in 2004 - I can find no one else who has this camera, makes me feel very lonely. :)
You can extend it to 4 different focal lengths (150mm, 120mm, 75mm and 40mm), and there is a corresponding pinhole and a zone plate for each, accessed along a sliding piece of wood on the front (no zoneplate for the 40mm setting). Takes 4x5 film holders on the back. While I have picked up some 4x5 film holders, I'm no where near ready to process sheet film or photo paper cut to fit, so I also have a Graflok back which I hope someday to attach to the camera so I can use a number of different film adapters with it (including Polaroid packfilm and 120 film). Only problem is to do that I have to work up the nerve to hack off the wooden bits glued to the back in order to lay the Graflok flush against the back of the camera - I haven't gotten up the courage yet to cut into the thing, I'm worried I'll screw it up...

Pinhole Pinhole Photography - History, Images, Cameras, Formulas
According to Renner (1995: 117) most formulas used today are of the following general form:
r = sqrt (l * c * f)
r = pinhole radius
l = wavelength of light
c = a constant, usually a decimal fraction between 0.5 and 1
f = focal length
l = wavelength of light
c = a constant, usually a decimal fraction between 0.5 and 1
f = focal length
Platt (1989:73) provides the following optimal pinhole formula:
d x d = f/k, where k is a constant of approx. 1300
d x d = f/k, where k is a constant of approx. 1300
Dobson (1991) provides this formula:
d = sqrt (f)/25
d = sqrt (f)/25
Lord Rayleigh's formula and those published by Platt and Dobson all give somewhat different results. Andrew Davidhazy of the Rochester Institute of Technology lists several other formulas in a posting on the net.
Four, slightly different, charts of optimal pinhole diameters are reproduced below. Some of the charts have been simplified by leaving out references to needle numbers. Holter's chart, published in Norwegian, has been translated by me. Platt's chart differs from the others by consistently giving smaller apertures.

It should be borne in mind that for most purposes the diameter is not really critical, as the different values in the charts above may demonstrate.

Chamaeleon Panorama 618 with exchangable lens boards - skinkpinhole - Juergen Kollmorgen
initially I designed this pinhole / lens hybrid panoramic camera for myself. It has exchangeable lens boards and produces panoramic photographs in 6x18 cm format. The curved film-plane helps to minimize vignetting (light fall-off). It's adjustable film-chamber allows the use of different pancake-style wide-angle lenses, like Schneider Angulon 90mm or Symmar 100mm. Some limited edition collectors' cameras will be available in ebay soon...

HOW TO BUILD A PANORAMIC CAMERA
Giorgio Carboni, November 2002
Translation edited by Charles and Mary Perry
In this type of camera, the vertical field is small in relation to the horizontal one. This is justified because subjects for panoramic shots, especially if they are distant, are usually arranged along the horizon. But what if your shot is a cityscape with tall buildings where a greater vertical field would be useful? To face this problem, this camera's objective has been mounted with an upward "shift", allowing the camera to shoot a wider field in this direction (figure 10).
This shift is also advantageous when shooting a subject from a high position, because by turning the camera upside-down, you will be able to take a wider angle downward.
The shift of the objective is 11 mm and allows the camera to obtain an angle of 28 degrees above the line of the horizon and 13 degrees 30 minutes below the horizon for a total of 41 degrees 30 minutes. You must be sure that the objective you want to use has enough area of coverage to avoid vignetting. If the objective won't shift that much without vignetting then you must reduce or do away with shift, or obtain another objective. If you do not understand this business of "shifting" the lens and "vignetting" then I recommend you do some research on those subjects in relation to view cameras.
