Both the High Quality Camera and Global Shutter Camera contain an IR filter, which is used to reduce the camera's sensitivity to infrared light. This ensures that outdoor photos look more natural. However, some nature photography can be enhanced with the removal of this filter; the colours of sky, plants, and water can be affected by its removal. The camera can also be used without the filter for night vision in a location that is illuminated with infrared light.
