Wow!
That is really dishonest.
And he entered it into a prestigious Photo Competition!
What a fool.
My Snake Valley by Night image is 2 images combined but at least I admitted it.
I focussed on the sky and went click for 10 seconds, then refocussed on the Foreground and went click for another 10 seconds (the light on the sign and grass is from my car's parking lights which was parked about 30 metres away!). Then I combined the 'focussed' foreground with the 'focussed' sky.
It even won a local Photo Competition, but I said how it was taken when the organisers asked.
I tried many times to get both the foreground and sky in focus at the same time with no luck, so that's why I combined the two frames.
At least mine is taken at one location, just 2 different focal points.
But geez, to try and pass it off as real!
Here's mine so you can see what I mean. You can tell it's Focus fiddled:
