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 (API control)
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 (API control)
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 (API control)
