Type
- determines the type of the camera. This mostly has an effect on the motion
blur effect produced by the camera:
Still camera - simulates a still photo
camera with a regular shutter.
Cinematic camera - simulates a
motion-picture camera with a circular shutter.
Video camera - simulates a shutter-less
video camera with a CCD matrix.
Targeted - specifies whether the camera
has a target in the 3dsmax scene or not.
Film gate - specifies the horizontal size
of the film gate in milimeters. Note that this setting takes into account
the system units configuration to produce the correct result.
Focal length - specifies the equivalen
focal length of the camera lens. This setting takes into account the system
units configuration to produce the correct result.
Zoom factor - specifies a zoom factor.
Values greater than 1.0 zoom into the image; values smaller than 1.0 zoom
out.
Target distance - the distance to the
camera target for a targeted camera.
f-number - determines the width of the
camera aperture and, indirectly, exposure. If the Exposure option is
checked, changing the f-number will affect the image brightness.
Distortion - specifies the distortion
coefficient for the camera lens.
Distortion type - Quadratic / Cubic.
Quadratic this is the
default distortion type. It uses a simplified formula that is easier to
calculate than the Cubic method.
Cubic this is the distortion type used in
some camera tracking programs like SynthEyes, Boujou etc. If you plan on
using one of these programs, you should use the Cubic distortion type.
Vertical shift - allows the simulation of
shift lenses for 2-point perspective. Changing this parameter is similar to
applying a Camera correction modifier. Use the <Guess
vertical shift> button in order to achieve the 2-point perspective.
Specify focus - this allows you to specify
a focus distance different from the camera target distance.
Exposure - when this option is on, the
f-number, Shutter speed and ISO settings will affect the image brightness.
Vignetting - when this option is on, the
optical vignetting effect of real-world cameras is simulated.
White balance - allows additional
modification of the image output. Objects in the scene that have the
specified color will appear white in the image. E.g. for daylight scenes
this should be peach color to compensate for the color of the sun light etc.
Shutter speed - the shutter speed, in
inverse seconds, for the still photographic camera. For example, shutter
speed of 1/30 s corresponds to a value of 30 for this parameter.
Shutter angle - shutter angle (in degrees)
for the cinematic camera.
Shutter offset - shutter offset (in
degress) for the cinematic camera.
Latency - CCD matrix latency, in seconds,
for the video camera.
Film speed (ISO) - determines the film
power (i.e. sensitivity). Smaller values make the image darker, while larger
values make it brighter.
Blades - defines the shape of the camera
aperture. When this option is off, perfectly circular aperture is simulated.
Rotation - defines the rotation of the
blades.
Center bias - defines a bias shape for the
bokeh effects.
Anisotropy - allows stretching of the
bokeh effect horizontally or vertically to simulate anamorphic lenses.
Depth-of-field - turns on depth of field
sampling.
Motion blur - turns on motion blur
sampling.
Subdivs - determines the number of samples
(rays) for calculating depth of field and/or motion blur.
