Somehow I find their hdr mode quite washed out... What am I doing wrong ****
The computational (software processing/ aka out of the box) side is always the weakness of the Xperia line.
So the HDR is weaker than norm. (Best HDR is like the Pixel 6 Pro's but you can argue that their HDR is soooo fake, the picture almost looks flat with barely enough contrast. I am starting to see trends from phones that they are trying to reign in the over processing to make images more natural)
Unless you do the traditional-photography multi exposure shots and combine which is too much effort imo.
My 2 cents with X1iii and Xproi is that if you do not go raw with some processing effort, you are likely to be disappointed with most of their out-of-the-box/point-and-shoot shots (if you compare with any flagship grade phones camera). In another words, if you go raw, you have to do a lot of work with HDR.
Xproi does differentiate itself with the very good videography though especially if you familiarize with the shutter speed settings while videoing for quality vs shake/video-jelly-effect.
and 1 last thing, their selfie camera (while serviceable) is just bad...
