This page provides information about the Camera tab functionalities in Chaos Vantage. 

 

Overview


The Camera tab allows control over the camera.

It has five pop-up windows - Resolution, Sensor and Lens, Exposure, Depth of Field and Tilt and Shift, that offer finer control. 

You can use the right mouse button click to reset the parameters numeric values to defaults.

 

 

Parameters


Navigation

Move speed – Specifies the speed at which the camera moves. The value is in meters per second.

Eye height – Sets the eye height for the camera in meters when in Free look() mode and Collisions() enabled.

Basic

Resolution Preset – Resolution preset allowing you to choose the resolution. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

Focal length/Field of view – Specifies the equivalent focal length or field of view value of the camera lens. Listed parameter depends on the Lens Mode setting in the advance options. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

Exposure value/Film speed(ISO) – Specifies the exposure value or ISO of the camera. Listed parameter depends on the Exposure setting in the advance options. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

White balance – Allows additional modification of the image to compensate for the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Objects in the scene that have the specified color will appear white in the image.

White balance will only work when Exposure is set to either Physical or Value. When Exposure is None, White balance will be disabled.

Depth of field – Enables the depth of field effect. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

Automatic vertical tilt correction – When enabled, sets and preserves vertical lines to be parallel, simulating 2-point perspective. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

Camera clipping – When enabled, turns on the camera clipping. Press the () button to open the advanced options window. Press again the () button to close the advanced options window.

Create New Camera – Saves the current camera view to a new camera slot. (Shortcut: Ctrl+K )

Save (Overwrite) () – Overrides the current camera slot with the current camera view. (Shortcut: Ctrl+Shift+K )

Delete ()– Deletes the camera slot. It has to be clicked twice.

You can switch between the camera slots using the Home and F1-F12 keyboard keys.
 

 

 

Advance parameters


 

Resolution


The Resolution preset pop-up menu allows you to choose the resolution.

To choose different aspect/resolution press the Lock/unlock button ().

The Fill button () extends the render until it fills the viewport width with the specified resolution aspect. The value next to it displays the zoom factor between the current viewport size and the render specified when Fill is enabled.

 

 

 

Sensor & Lens


Lens Mode – Specifies which lens parameter to display for the camera:

Focal length – Displays the focal length value of the camera in the Camera tab Basic category.
Field of view – Displays the field of view value of the camera in the Camera tab Basic category.

Focal length – Specifies the focal length of the camera in mm. (Shortcut: Alt+RMB)

Field of view – Specifies the field of view of the camera in degrees. (Shortcut: Alt+RMB)

Film gate – Specifies the horizontal size of the film gate in millimeters.

Zoom factor – Specifies a zoom factor. Values greater than 1.0 zoom into the image; values smaller than 1.0 zoom out.

 

 

 

Exposure


Exposure – Specifies how the F-numberShutter speed, and Film speed (ISO) settings affect the image brightness.

NoneShutter speed, F-number and ISO settings do not affect the image brightness.
Physical – Image brightness is controlled by the Shutter speed, F-number and ISO. Grays out Exposure value.
Value – Uses the Exposure value to control image brightness. Grays out the ISO parameter and uses F-number values only for depth of field if Aperture size is disabled.

Exposure Value – Controls the image brightness.

Film speed(ISO) – Determines the sensitivity of the film and consequently the brightness of the image. If the ISO value is high (film is more sensitive to light), the image is brighter. Lower ISO values mean that the film is less sensitive and produces a darker image.

F-Number – Controls the aperture size of the 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 Depth of Field (DOF) effect. Changing the f-number will affect the image brightness and DOF when the Exposure option is set to Physical.

Shutter speed – Determines the exposure time for the camera. The longer this time is (small shutter speed values), the brighter the image would be. In reverse - if the exposure time is shorter (high shutter speed value), the image would get darker.

 

 

 

Depth of Field


Focus distanceSpecifies the distance at which objects are in focus. (Shortcut: Ctrl+Alt+LMB)

Aperture size – Determines the width of the camera aperture in millimeters. When enabled overrides F-Number.

Center bias – Defines a bias shape for the bokeh effects. Positive values make the outer edge of the bokeh effects brighter; negative values make the center of the effect brighter.

Anisotropy – Allows stretching of the bokeh effect horizontally or vertically to simulate anamorphic lenses.

Polygonal – When enabled, a polygonal aperture is simulated, with the specified number of blades.

Num sides – Specifies the number of blades for the polygonal aperture.

Rotation – Defines the rotation of the blades in degrees.

 

Tilt & Shift


Vertical Tilt – Sets the vertical tilt of the camera lens. You can use this to correct  perspective to achieve parallel vertical lines similar to 2-point perspective.

Horizontal tilt –Sets the horizontal tilt of the camera lens. You can use this to correct  perspective to achieve parallel horizontal lines.

Horizontal shift – Horizontally offsets the camera field of view as a fraction of the current view. For example, a value of 0.5 will offset the camera one-half of the current image width to the left.

Vertical shift – Vertically offsets the camera field of view as a fraction of the current view. For example, a value of 0.5 will offset the camera one-half of the current image height upwards.

 

 

 

Clipping


Near – Specifies the near clipping range.

Far –Specifies the far clipping range.
