Let´s see some desert photos

No. I filtered out all blue light with the editor to get the old black sky effect.

Edit: That was not a very clear explanation. I used the photo editor Affinity which is available as a free download. I converted the original picture to B&W and when you do that the editor allows you to choose how much of each color contributes to the final image. I didn't add anything that was not already there, just messed around with it.
