This is my entry for the Smart-photo contest.
I do not have photos of real fire made on a smartphone, but it seems to me that my photo still fits with the topic of the contest, because the name skies in fire is very suitable for it.
A few weeks ago I was returning home from another city and watched such a beautiful sky. I could not resist and took a picture of it on the smartphone.
I have used an Adobe Lightroom app for postprocessing.
