| |
| Note that when converting a colour from regular LSL space (sRGB) to linear space for use in a light, it's likely quicker and cleaner to use the internal function [[llsRGB2Linear]]. This is mostly a function that can be used for fun to manipulate the gamma space of colours.

| == Lens Settings ==
| |
| The below contains settings for simulating various real-life lenses within Second Life. These settings will change the camera's Field of View (FoV), as well as Depth of Field (DoF) settings. You may want to play around with some of these settings (for example, the Aperture value) to manipulate the depth-of-field effect.
| |
| | |
| {{KBtip|The default Second Life camera is roughly equivalent to a full frame digital (36x24mm sensor) camera using 35mm lens.}}
| |
| | |
| For reference, the following table describes the debug settings changed, their units, and what the setting does. Default values are not provided as these settings may vary between viewers.

| |
| | CameraAngle || [[Radians]] || Camera Field-of-View angle, diagonal. Equivalent to Angle of View - diagonal degrees to equate a real lens. This changes the '''visible''' FoV.

| |-
| |
| | CameraDoFResScale || Linear || Amount to scale down resolution of DoF effect. Manipulating this value may change performance.
| |
| |-
| |
| | CameraFieldOfView || Degrees || Field-of-View angle used for the DoF effect. Note that this value is the '''vertical''' FoV, NOT diagonal.
| |
| |-
| |
| | CameraFNumber || F Stop || F Stop (or Aperture) value to be simulated by DoF effect.
| |
| |-
| |
| | CameraFocalLength || mm || Focal length of the lens to be simulated by the DoF effect.
| |
| |-
| |
| | CameraMaxCoF || mm*1000 || Lens Circle of Confusion value to be simulated by the DoF effect.
| |
| |-
| |
| | CameraFocusTransitionTime || Seconds || Time the camera will take to transition between 2 focal planes.
