I’ve mentioned before that sometimes color plays no role in an image. When this is the case, look to desaturate:
This was created during the lunar eclipse, and referred to in this post. Completely orange in the original due to tungsten lighting, but it somewhat works in black & white. It’s not an earth-shaking image, but I do like the contrasts of the organic & mechanical, as well as the deep dark of the sky.
