The Change field of view feature makes the camera switch to using a wider or narrower lens to show more or less of the drawing during a specified transition segment. Between a starting point and an end point, the camera lens becomes either narrower or wider, depending on the number set. When the camera reaches the end point of the transition segment, it returns to the original field of view until there is a new change, or for the remainder of the path. Along a single camera path there can be several segments, preferably one after another.
To change the field of view between two points, follow these steps:
- Define a camera path by following the instructions found in the chapter Placing a Camera Path or Stationary Camera (1).
- Click the Change field of view button on the Movie Studio component tab.
- Move the cursor to the drawing area. A red V icon is attached to the cursor. The icon snaps to the camera path to indicate the segment starting point (2), and an input field at the top left corner lets you enter a new field of view. You can enter your desired field of view now, or edit it later in the quick properties box.
- Click to set the starting point in the desired position. A second angle icon immediately snaps to the camera path to indicate the segment end point (3).
- Click to set the end point in the desired position.
- A new angle icon is now attached to the cursor. If you wish to make further field of view changes to another segment of your path, repeat the previous two steps. If you do not wish to make further changes, move the cursor off the drawing area or press the Esc key on you keyboard to release the tool.
- To edit the properties of the segment, select it in the drawing and edit the settings in the green quick properties box (4).
After placement, you can select the segment and set the transition, i.e. how quick the transition to the new value should be at the beginning and the end of the segment. The default transition is 30%.
Example: A camera path in the 2D view with 1) playback starting point; 2) segment starting point; 3) segment end point, and 4) property box for setting the field of view between the two points. In this example, the path begins at a 60 degree field of view, which narrows down to 30 degrees at point 2. It then remains at 30 degrees until point 3 where it widens back up to 60 degrees.
To select the segment of the path, you can left-click. This may initially select the entire path, so left-click again until just the segment is selected. Alternately, you can hold down Ctrl on your keyboard and right-click to see a list of all objects under your cursor and choose Change field of view event.
