Example: Zoom Factor

This parameter determines the zooming (In and Out) of the final image. It doesn't move the camera forward nor backwards.

Exposure is on,  f-number  is 8.0,  Shutter speed is 60.0,  ISO is 200.0,  Vignetting   is on,  White balance  is white.

Example: Exposure Control - f-number (f-stop)

Note: All the images from the following examples are rendered using the VRaySun and VRaySky set with their default parameters.

This parameter controls the aperture size of the virtual camera. Lowering the f-number value increases the aperture size and so makes the image brighter, since more light enters the camera. In reverse, increasing the f-number makes the image darker, as the aperture is closed. This parameter also determines the amount of the DOF effect, see   Example .  

Exposure is on,  Shutter speed  is 60.0,  ISO is 200,  Vignetting is on,  White balance  is white.

Example: Distortion

The difference between the two types of distortion is slightly visible. The  Cubic  type should be used in some camera tracking programs like  SynthEyes ,  Boujou,  etc.

Example: Vertical Shift (Camera Correction)

Using this parameter you can achieve the so called " 2 point perspective ". To have that done automatically, use the  Guess vertical tilt  button.

Example: Vignetting

This parameter controls the simulating the optical vignetting effect of real-world cameras.

Example: White Balance

Using the white balance color 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.

Exposure is on,  f-number  is 8.0,  Shutter speed  is 200.0,  ISO is 200.0,  Vignetting is on.

Example: Exposure Control - Shutter Speed

This parameter determines the exposure time for the virtual camera. The longer this time is (small Shutter speed value), the brighter the image would be. In reverse - if the exposure time is shorter (high  Shutter speed  value), the image would get darker. This parameter also affects the motion blur effect, see  Example .

Exposure is on,  f-number  is 8.0,  ISO is 200,  Vignetting is on,  White balance  is white.

Example: Exposure Control: Film Speed (ISO)

This parameter determines the sensitivity of the film and so the brightness of the image. If the film speed (ISO) is high (film is more sensitive to the light), the image is brighter. Lower ISO values mean that the film is less sensitive and produces a darker image.

Exposure is on,  Shutter Speed is 60.0, f-number is 8.0,  Vignetting  is on,  White balance  is white.

Example Motion Blur Example Motion Blur

Example: Motion Blur (MB)

To enable the motion blur effect, you need to turn on the  Motion blur  checkbox in the Sampling rollout of the physical camera. The amount of the motion blur is determined by the speed of the moving object itself as well as the  Shutter speed  setting of the camera. Long shutter speeds will produce more motion blur, as the movement of the object is tracked over a longer in time. In reverse, short shutter speeds will produce less motion blur effect. Keep in mind that to preserve the same illuminosity over the whole image, the  f-number value has to be corrected as well.

Note that in the example the far object is moving quicker than the near one, which cases the difference in the motion blur effects.

Exposure is on,  ISO is 200.0,  Vignetting is on.
