HDR picture from the Photomatix software. I would try to do like 3 or more levels of exposure of same picture then combine it into one. I'm not very experience with this and also I just got the software installed after so many years not using it. lol I used it often few years ago but the pictures got lost in recent hard drive crash. From what I remember it's better do this in raw format. Software I use. https://www.hdrsoft.com/index.html Camera: Canon 5d Mark II Lens: Canon EF 24–105mm F/4L
