This image caused great problems because of the low number of colours used, the lack of a defined edge between foreground and background, the varying background colours, and the poor contrast between foreground and background |

Good separation, apart from the lost shoulder, in part a consequence of low contrast. |

The background image is the map of the world shown above. The third image shows colour change as a result of too few colours in the GIF lookup table. |

This image caused problems for some students typically because of the left/ right approach they took when separating foreground from background. A top-down approach would have worked in this case because of the gray gradient in the background. |
