To magnify a photograph or a 3D Viewer:
• Pick up the Zoom-In tool from the ribbon toolbar’s Active Window Tab (the magnifying glass with a "+").
• Click this tool on the Photograph or 3D Viewer Window you wish to magnify.
PhotoModeler will magnify this window each time you click the mouse button. The photograph or 3D Viewer will magnify about the point specified by the cursor position. I.e. if you wish to study some feature more closely, click the zoom-in tool on top of it and it will be magnified and placed in the center of the window.
