fisk farger

The camera calculates the distance to everything it observes. In this image the depth of field is colour-coded. This makes it easy to see that the pink fish is located at a distance of approx. 2.9 metres, while the green fish is 4 metres away. It is also easy to see that the blue fish is located in front of the green one. This makes it easier both to measure absolute size and to post-process images automatically.
