I hardly do much HDR as I have an awesome camera with great dynamic range. But still, there is a place to capture multiple exposures especially when you are pointing your camera towards the bright and strong light source. 3 exposures are usually enough to capture all luminance range but for this photo, I went a bit extreme with 9 exposures. I am kind of surprise with the overall rendition of the merged photo. Lightroom Merge took care of any ghosting I was worried about.
