# Camera
A **Camera** object provides the point of view for rendering, and unlike its real-life counterpart, they are invisible.


## Add Camera
To add a **Camera**, press <kbd>Shift + A</kbd> or <kbd>Left Mouse Click</kbd> to open the `Add` menu and choose `Camera`. Like any other object, you can move and rotate a camera, but scaling only affects its viewport representation. To look through the camera, press <kbd>Numpad 0</kbd> or <kbd>Left Mouse Click</kbd> the camera icon on the right edge of the viewport. If you want the camera to move with the view, tick `View > View Lock> Lock Camera to View`, otherwise moving the view when looking through a camera will exit the camera view.

## Active Camera
A scene can only have one camera working at a time, for obvious reasons, and it is called the **Active Camera**. The active camera has a solid triangle on its top, and the others have a hollow one. To change the active camera, select a camera and <kbd>Right Mouse Click</kbd> then choose `Set Active Camera`. If you want to do it during an animation, it is a bit more complicated. Set the current frame to 1 in the **Timeline** area and press <kbd>M</kbd> or `Marker > Add Marker` to add a marker at the frame, then select one camera and <kbd>Left Mouse Click</kbd> the marker and press <kbd>Ctrl + B</kbd> or choose `Marker > Bind Camera to Markers`. After that, move the current frame to the one on which you want to switch the active camera, and do the same for the other camera.

## Camera Properties
::::{tab-set}
:::{tab-item} Focal Length
`Lens > Focal Length` controls the field of view, the larger the number, the more zoomed in you are.

:::{tab-item} Clip
Parts of objects that get too close or too far from the camera will not be rendered, and this is called **Clip**. You can adjust its behavior by changing `Lens > Clip Start/End` values.

:::

:::{tab-item} Depth of field
Real lenses have focal points, and out-of-focus objects look blurry. the `Depth of field` property simulates that effect, and tweaking `Aperture` help to make it more realistic.
```{tip}
:class: margin
This effect is sometimes referred as **Bokeh**.
