Do you know where I could find informations about how this kind of shutter work, the #00, #0 or #1 lenses and how the lenses can adapt on this kind of system? I'm sorry, I'm very new to LF photography...
What's to know? A conventional cock-and-shoot shutter (best known makes, in alphabetical order, Ilex, Compound, Compur, Copal, Rapax/Graphex, Wollensak) has a cocking lever and a release lever. One cocks it with the cocking lever, fires it with the release. A press or self-cocking shutter (best known makes Compur Press, Copal Press, Prontor Press) has a cock/release lever. One fires it by pressing on the release. Both types usually have sockets or brackets that accept a cable release.
Leaf shutters (all of the above) typically have a rear tube with circular cross-section (duh) that's threaded externally. A leaf shutter is held to a lens board by screwing it into a flange that's attached to the lens board with, typically, three screws or by a retaining ring. The retaining ring screws on to the rear of the tube, the board is clamped between the ring and the back of the shutter.
In post #89 above Mnemosyne mentioned #00, #0 and #1 shutters. These are sizes. Although the meaning of the sizes has varied between manufacturers (see
http://www.suaudeau.eu/memo/pratique/Les_obturateurs_centraux.html
for a large but incomplete list) modern #00, #0, #1 from Compur, Copal and Prontor conform to the same standard. When posters here talk about #00, #0 and #1 shutters they usually mean Compur or Copal or Prontor.
Most press, technical, field and view cameras have lens boards that can be bored to accept any shutter that will fit. Folding cameras (press, technical, field) are limited to shutters that will fit between the struts. In the case of my 2x3 Graphics, the largest shutter that fits is an Ilex #3.
Anthony, you need an education. Asking questions on a bulletin board like this is a poor way to get one. Buy a book. The books most often recommended on the US large format forum are Steve Simmons' Understanding the View Camera and Leslie Stroebel's View Camera Technique. galerie-photo.com recommends Jim Stone's A User's Guide to the View Camera and Pierre Groulx' La photographie en Grand Format.
