Here's a particularly dramtic asperitas cloud, from NASA's astronomy picture of the day:

then
Image > Adjustments > Photo Filter > Sepia (Density 65 pct)
Was wondering what that could look like so created a mockup using an old 'Nature of Trees' .jpg:

There might be a market for it and maybe a useful source of funds for their Society.I did some flying down there, and not only do you see every type of cloud in a day, they change from one minute to the next.
IFR (I Follow Roads) navigation is still acceptable in NZ when the clouds come down to tree-top height and you're in a valley.
One of the most fantastic times of my life was flying a small airplane from North Island to South Island and back over the huge crater lakes. And lots of sheep!
