I’m having the same issues with the 14Pro camera. I was told I could return the iPhone 14Pro or wait for Apple to optimize the camera software as the current solution. The problem I am told byApple support is that the software processing is optimized for 12MP sensor and not the new 48MP sensor… yet..That’s why the iPhone 11-13 camera takes better photos when using it as a quick point and shoot.
For now in the Apple camera app, hold still, frame your shot, touch the screen to set focus and set exposure for a great photo.
The default camera app also over sharpens, evens exposure across the frame, and adds lightening to all areas and especially to faces in the image after 1-2 seconds. That’s why your sunset picture may look great when you take the shot but then is overly processed and the colors are washed out when stored.
If you don’t like the over processed images, you can use a 3rd party camera app until Apple is able to optimize the processing.
Hope this helps.
