Our next chapter is all about layer masks, so we don't need to discuss it any more here
except to point out that we can invert the layer mask — visible becomes hidden, hidden
becomes visible — which allows us to see the land instead of the sky. To do that, double
click on the mask icon for this layer in the layers panel. It will bring up another panel that
allows us to invert the mask.
