Superior Auto takes an 8mp image and crams it down into a 5, correct? Much like the Lumia 1020 does with the 41mp images (to 5) and the Z1 does with the 21mp images (to 8).
I noticed the file size is smaller. In manual mode, we obviously get more options, but we also get the full 8 mp shots. I have taken samples in both modes and they look pretty similar to me.
Which is better, in your opinion and which do you generally use?
