If the camera you are creating has already been used in a PhotoModeler project (and you have a copy of the project containing the camera, or a stored .cam file) you should select the “A calibrated camera (from library or from disk) or a camera previously used in PhotoModeler” radio button. This enables the controls which allow you to select a specific camera, from:
• the Camera Library, a central repository on disk where calibrated cameras are stored (see also Application Data and File Locations for information on location of this and other files used by PhotoModeler).
• the project in which the camera was used. Click Browse… to find the appropriate project. If the selected project contains more than one camera, a dialog box shows the list of cameras in the project allowing you to select the one you want loaded.
