Camera Effects

Exposure settings

Camera Mode	The camera mode, which determines the way the exposure is set. Either of the following: Physically-Based - the real-world values are used to set up lighting and camera exposure: ISO, shutter speed, F-stop. With the default values of these parameters, the static exposure value is near 1. Notice For the physically-based mode, the exposure mode should be set to Static to avoid exposure issues. Classic - the exposure is set by the Exposure value. Option #1 is selected by default (see above). Console access: render_camera_mode
Exposure Mode	The mode of the adaptive exposure effect. Static — a static exposure. The amount of luminance is determined by the Exposure depending on the Camera Mode parameter. Logarithmic adaptive — adaptive logarithmic mapping technique. Quadratic adaptive — adaptive quadratic mapping technique. Option #1 is selected by default (see above). Console access: render_exposure_mode

Classic Camera Model Settings#

Exposure

The camera exposure (a multiplier of the scene luminance and brightness).

It determines the resulting amount of luminance:

By the minimum value of 0.0f, the image is rendered black.
The higher the value, the more luminance and the brighter the scene lit.

Available only when the Camera Mode is set to Classic.
Range of values: [0.0f, 4.0f]. The default value is 0.0f.
Console access: render_exposure

Exposure = 0.2

Exposure = 1

Physically Based Camera Model Settings#

ISO	The ISO value used for static exposure calculation. This value is available for the physically-based camera and represents the sensitivity of the camera sensor. The higher the ISO number, the more light is collected and the brighter the image is. Range of values: [0, inf]. The default value is 100. Console access: render_iso
Shutter Speed	The shutter speed used for static exposure calculation. This setting is available for the physically-based camera and indicates how long the sensor of the camera is actively collecting light. Higher values make the shutter speed faster and the image — darker. Range of values: [0, inf]. The default value is 250. Console access: render_shutter_speed
F-Stop	The f-stop value used for static exposure calculation. This setting is available for the physically-based camera and represents the ratio of the focal length (f) and the diameter of the lens opening (D): f / D. It is the reciprocal of the relative aperture. The higher the value, the darker the image is. Range of values: [0, inf]. The default value is 11. Console access: render_f_stop

Logarithmic or Quadratic Adaptive Settings#

Adaptation

The time for the camera to adjust exposure, in seconds. 0.0f - means instant adaptation. If a too small or even negative value is provided, 1E-6 will be used instead.
Range of values: [0.0f, inf]. The default value is 1.0f.
Console access: render_exposure_adaptation

Min Luminance

The minimum luminance offset relative to the default luminance of the scene used for rendering of the adaptive exposure effect. The higher the value, the darker the adapted image is.
The parameter can take on negative values.

NoticeIf the specified value is greater than the current maximum luminance, the maximum luminance value will be changed to the specified minimum luminance so that they are equal.

Min Luminance = -1

Min Luminance = 2

Max Luminance

The maximum luminance offset relative to the default luminance of the scene used for rendering of adaptive exposure effect. The lower the value, the brighter the adapted image is.
The parameter can take on negative values.

NoticeIf the specified value is less than the current minimum luminance, the minimum luminance value is changed to the specified maximum luminance so that they are equal.

When checking the current parameter value via API you'll get the corresponding setting stored in the active preset (default or custom one).
