The Change field of view feature makes the camera switch to using a wider or narrower lens to take in and show more or less of the drawing during a specified transition segment. Between a starting point and an end point, the camera lens turns either narrower or wider. 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.
- 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.
- 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, repeat steps 2-3. 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.
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 speed 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.
