Color and contrast
While Auto mode on both phones is very good, sometimes it’s worth getting a firmer grasp with Pro mode to improve composition, because Auto won’t always get the color and contrast right.
For example, shooting a sunset in Auto tends to raise the shutter speed, lower the ISO, and adjust the white balance to avoid washing out the whole image. It’s not a bad result, but the software is also being cautious by not going far enough.
If you’re facing a situation where there’s a lack of depth or detail, try tinkering with the shutter speed, ISO, and white balance — in that order. Adjusting the shutter might be enough on its own, but having the other two as fallbacks should help you come out with a better shot.
The wider aperture on both phones is fixed, so even in instances like a sunset, the amount of light coming in is going to be fairly high, regardless. That can mess with colors and make what should be a dynamic scene look pedestrian. With better color and contrast, photos will look more artistic and interesting. The Pro mode’s manual settings make it easy to get there.
