Sometimes you just don't get the light that you want.
It happens a lot. You are going somewhere special, and you have a vision in your mind of what a stunning sunset will look like from a specific vantage point that you have never visited. So you plan ahead, get there with plenty of time, have all the right gear, and the light is crap. Totally boring.
Sadly, it does happen and there is nothing you can do about it at the moment. But part of the fantastic fun of post-processing for me is that you can interpret the scene artistically later if you want to. I don't do this much, but sometimes it a great exercise for crafting a photo that fits the vision you held in your mind for so long.
That's what I did with this photo. The light was totally boring, and although the view was incredible, the photos I took were underwhelming. So I went into Luminar and added a lovely sunset sky to replace the boring one I witnessed. I think that is totally ok to do, as long as you let your viewers know that it's an artistic interpretation and not exactly what you shot.
