The Film Back options control the basic properties of a camera (for example, the camera's film format: 16mm, 35mm, 70mm).
- Film Gate box
-
Select a preset camera type.
Action automatically sets the corresponding Camera Aperture, Film Aspect Ratio, and Lens Squeeze Ratio. To set these attributes
individually, set Film Gate to User. The default setting is User.
- Camera Aperture fields
-
Display the height and width of the camera's Film Gate setting, measured in inches. The default values are 1.417 and 0.945.
This setting has a direct effect on the camera's angle of view.
- Film Aspect Ratio field
-
Displays the ratio of the camera aperture's width to its height. Maya automatically updates the Film Aspect Ratio (and vice
versa). The valid range is 0.01 to 10. The default value is 1.5.
- Lens Squeeze Ratio field
-
Displays the amount that the camera's lens compresses the image horizontally. Most cameras do not compress the image they
record, and their Lens Squeeze Ratio is 1. Some cameras (for example, anamorphic cameras), however, compress the image horizontally
to record a large aspect ratio (wide) image onto a square area on film. The default value is 1.
- Film Roll Value field
-
Specifies, in degrees, the amount of rotation applied around the film back. The rotation occurs around the specified pivot
point. This value is used to compute a film roll matrix, which is a component of the post-projection matrix.
- Film Roll Rotation Order box
-
Select how the roll is applied with respect to the pivot value.
Enable: |
To: |
Rotate-Translate |
First rotate the film back, then translate it by the pivot point value. |
Translate-Rotate |
First translate the film back, then rotate it by the film roll value. |
- Pre Scale field
-
Displays the artificial 2D camera zoom that is applied before the film roll. The Pre Scale value is used in 2D effects.
- Post Scale field
-
Displays the artificial 2D camera zoom that is applied after the film roll. The Post Scale value is used in 2D effects.
- Film Fit Resolution Gate box
-
Select the size of the resolution gate relative to the film gate (Film fit). If the resolution gate and the film gate have
the same aspect ratio, then the Film Fit setting has no effect. The default setting is Fill.
Select: |
To: |
Fill |
Fit the resolution gate within the film gate. |
Horizontal |
Fit the resolution gate horizontally within the film gate. |
Vertical |
Fit the resolution gate vertically within the film gate. |
Overscan |
Fit the film gate within the resolution gate. |
- Film Fit Offset field
-
Displays the offsets, in pixels, of the resolution gate relative to the film gate either vertically (if Film Fit is Horizontal)
or horizontally (if Film Fit is Vertical). Film Fit Offset has no effect if Film Fit is Fill or Overscan. The default setting
is 0.
- Film Offset fields
-
Displays the vertical and horizontal offsets, in pixels, of the resolution gate and the film gate relative to the scene. Changing
the Film Offset produces a two-dimensional track. The default setting is 0.
Enter: |
To: |
1 |
Have the view guide fill the view. The edges of the view guide may be exactly aligned with the edges of the view, in which
case the view guide is not visible.
|
> 1 |
Increase the space outside the view guide. The higher the value, the more space is outside the view guide. |
- Film Translate fields
-
Display the artificial 2D horizontal and vertical camera pans. The Film Translate values are used in 2D effects.
- Film Roll Pivot fields
-
Display the horizontal and vertical pivot points from the center of the film back, in pixels. The pivot points are used during
the rotating of the film back. These double-precision parameters correspond to the normalized viewport. The Film Roll Pivot
values are used to compute the film roll matrix, which is a component of the post projection matrix.
