Here's my first attempt at doing it the above photoshop video way.

I made this image using a simple Bump-Map.

First I found a black/white image of a "crop circle" design.
The background of the image was white,
so I did a Color to Alpha on the white.
Leaving the black lines behind.
Next I adjusted the Brightness/Contrast,
pushing the Brightness Slider to it's maximum.
This made the black lines a Middle Gray color ie. #808080.
Then I ran Map>Bump Map,
with Invert Bumpmap checked,
with no other changes to the bump map settings.
