The first image serves as a reference image. This is a straight conversion to black and white in the software with default settings. The end result is again a fairly flat image. The blackest blacks are not totally black although there are some proper whites.
Here is the default conversion...

To create the depth I really needed to draw the eye to the sky area and emphasize the cloud layers. Most of this was achieved by working on the blue and aqua sliders. After some adjustment I was able to return to the exposure slider to brighten the image back up again. This allowed further tweaking of the image.
The end result can be seen below.

Much as in the previous exercise, I was able to push the processing a very large amount. We are again deviating from reality but in black and white this seems more acceptable.
