A camera effects list contains features specific to the usual SLR camera. To tweak, use Rendering panel -> Camera Effects.
|Threshold||Brightness threshold used to determine areas to be illuminated:
|Dirt Scale||Intensity of the dirt texture.|
|Dirt||A texture that creates an effect of dirty camera lens. For example, it can be used to create an effect of light reflections or unclean optics when the camera looks at the sun.
Example of dirt texture
If you can't see the dirt texture, try tweaking the threshold parameter.
|Temporal Filtering||Reduces flickering of the bloom effect on the small bright objects (such flickering may appear when the camera moves). For example, it can be used in scenes with industrial pipes.|
|Camera Mode||Camera mode, determines the way the exposure is set:
Can be controlled via the render_camera_mode console command.
|Exposure Mode||Exposure mode:
Can be controlled via the render_exposure_mode console command.
|Exposure||Camera exposure. It determines the resulting amount of luminance:
This parameter is available only when the Camera Mode is set to Classic.
Can be controlled via the render_exposure console command.
|ISO||ISO number represents the sensitivity of the camera sensor. The higher the ISO number, the more light will be collected and the brighter the image will be.|
|Shutter Speed||Shutter speed indicates how long the sensor of the camera is actively collecting light. The higher the value, the faster the shutter is and the darker the image will be.|
|F-Stop||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 will be.|
|Adaptation||Time in seconds for the camera to adjust exposure (0 is for instant adaptation).|
|Min Luminance||The minimum luminance offset relative to the default luminance of the scene used for rendering of adaptive exposure effect:
If 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.
|Max Luminance||The maximum luminance offset relative to the default luminance of the scene used for rendering of adaptive exposure effect:
If the specified value is less than the current minimum luminance, the minimum luminance value will be changed to the specified maximum luminance so that they are equal.
The filmic tone mapping provides better image quality. It lightens the darkest image regions and makes the lightest regions darker.
All of the parameters described below represent the tone mapping curve, which is constructed by using the following formula:
- A - Shoulder Scale
- B - Linear Scale
- C - Linear Angle
- D - Toe Scale
- E - Toe Numerator
- F - Toe Denominator
For more details about tone mapping curve construction see the article on An efficient and user-friendly tone mapping operator.
The parameters described below are available only when filmic tone mapping is enabled (Rendering -> Camera Effects -> Filmic tone mapping).
|Enabled||Enables filmic tone mapping.|
|Shoulder Scale||The Shoulder Strength filmic tone mapping parameter value that is used to change bright values.
|Linear Scale||The Linear Strength filmic tone mapping parameter value that is used to change grey values. The Linear Scale controls the length of the tone mapping curve linear part.
|Linear Angle||The Linear Angle filmic tone mapping parameter value. This parameter controls the slope of the linear part of the tone mapping curve.
|Toe Scale||The Toe Strength filmic tone mapping parameter value that is used to change dark values. The Toe Scale controls the slope of the tone mapping curve toe (the area of underexposure).
|Toe Numerator||The Toe Numerator filmic tone mapping parameter value.
|Toe Denominator||The Toe Denominator filmic tone mapping parameter value.
|White Level||The Linear White Point filmic tone mapping parameter value, which is mapped as pure white in the resulted image.
The parameters described below are available only when cross flares are enabled (Rendering -> Camera Effects -> Cross).
The parameters described below are available only when the light shaft effect is enabled (Rendering -> Sun Shafts).
|Enabled||Enables sun shafts.|
|Color||The color of light shaft.
|Scale||Scale of the sun shafts, higher values produce larger shafts.
|Length||Length of light shaft.
|Attenuation||How fast the shafts fade out along their length:
|Threshold||Brightness threshold for sun to generate light shaft:
The parameters described below are available only when lens flares are enabled (Rendering -> Lens).
|Enabled||Enables lens flares.|
|Color||The color of lens flares.
|Scale||A multiplier for a color of lens flares.
|Length||Length indicating if the whole radial lens flare is rendered on the screen or only a part of it. This option controls how lens flares pattern is distributed.|
|Radius||A radius of the spherical lens flares on the screen.
|Threshold||The brightness threshold for areas to produce flare:
|Red||Color displacement for the red channel of the lens flares.
|Green||Color displacement for the green channel of the lens flares.
|Blue||Color displacement for the blue channel of the lens flares.
