After doing many HDR photos I feel I have nailed it. Of course not all photos will turn out great, but my percentages have increased.
Here are some tricks I learned:
Use a tripod or hold the camera really damn still. I dispise having to carry around a big ass tripod with me, although without it, it’s hard to get good looking photos that are not blurry. This is due to the fact that an HDR photo is a combination of a few photos.
Take 3 photos. And have these 3 photos be RAW photos if your camera allows
Keep the ISO low. Your photos can become very noisey if there is even the least bit of noise in your HDR
