Parameter name | What it controls |
|---|---|
Focal length | The focal length of the camera "lens". See the Camera page - Focal Length section for an indepth explanation |
Lock Exposure | Allows you to connect the Shutter and f-Stop parameters together so that when you change one, the other updates to maintain the same exposure. For example if you change the f-Stop the Shutter will automatically change to keep the same exposure. if you change the Shutter, the f-Stop will change to maintain the exposure. |
Shutter | Controls the Shutter of the virtual Camera. The shutter is a mechanical "curtain" inside a camera that opens and closes very quickly, determining how much time the film or sensor is exposed to light. The unit is in hundreds of a second, so a shutter-speed of 100 means the sensor is exposed to light during 100th of a second. Faster shutter-speeds decrease the exposure and produce darker images. This parameter is useful when doing animations, or still renders with a moving object, because it also controls the amount of motion blur seen on the object - longer shutter speeds (ie 1/2 a second, or 1 second or more will produce more motion blur on the object). When doing a render of with non moving objects this parameter can be ignored. You can still use it to control the exposure of the render if you like, but changing the ISO parameter in this case will have the exact same effect. |
f-Stop | Controls the size of the aperture of the camera "lens". This parameter affects both exposure and depth of field. See Camera page - Fstop F-stop section for an indepth explanation |
