Set the aperture on the camera to enable you to view the scene.

> ✅ **Tip**  
> ✅ For a 5 m x 5 m volume, set the aperture to 1.8.

If the image that you see of the subjects isn't sharp enough, ensure the volume is sufficiently and evenly lit, and focus the camera so that you can see a clear image of the subjects throughout the volume (or within the part visible to the camera).

To focus the camera, loosen the grub-screw above the lens and screw the entire lens in/out.
