I'm just gonna lay it out here. I work in fashion photography. I'm a makeup artist - color is my job.
The display on the 12s is BAD and just plain ugly. The camera for photographing objects is okay but for photographing people it sucks. It has this hyper-realism. It's too saturated and oversharpens everything. Nothing about it is "true" to the subject. The white balance on the display is completely off. When you try to adjust you will still be left with something that's either a little too yellow, a little too magenta, a little too cyan or a little too blue. It is CRAZY making to me. The particular glow of the OLED dispaly is also very unpleasant. The entire time I am thinking "What am I looking at here?" "What does this really look like??". Also, for photographing faces, wide angle is probably the least flattering you could ever opt for.
It's too bad because as an object the phones are really beautiful and feel great to hold - the mini especially. But the display and the camera is an absolute fail as far as I'm concerned. And these phones are supposed to be ALL about the CAMERA! lol
I returned both the 12 and the 12 mini because I was irked every time I had to look at the screen. Not the experience I want to a have all day everyday. I am honestly shocked at Apple. Don't they have artists on their team??
