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 - F-stop section for an indepth explanation |
EV number | Stands for Exposure Value. It lets you easily change the exposure of a scene in predefined steps. For example if you wish to make the render twice as bright, increase the EV by one whole number (ex. from 10 to 11). Changing the EV number will automatically update the Shutter parameter to adjust the exposure. |

Preset | Common camera presets. A camera preset changes the Filmback parameter to correspond to the physical size of the digital sensor or film in that camera. This will ensure your render will have the correct image aspect ratio for easier compositing of a render in a photo taken with that particular camera. |
Resolution | The horizontal and vertical (width and height) resolution of the render in pixels. The lock Icon allows you to lock the aspect ratio so when you change one parameter the other updates. |
Filmback | The physical width and height of the digital sensor or film of the camera. Please see the Camera - Filmback section for more detailed information. |
Pixel aspect | Width--height proportion of the pixels. Useful when the rendering output will be displayed on devices which have non-square pixels, such as television sets. |
