The iPhone XS’ camera is amazing, but put an unedited shot next to an unedited photo from the older iPhone X, or one of Google’s Pixel phones, and it looks a little flat. To “fix” this, you can tap the auto-enhancing Magic Wand tool on the edit screen, but this takes things too far in the opposite direction, making faces as orange as Florida bodybuilders.
I actually prefer the less-gaudy images from the XS, but sometimes they need a little extra pop. And the good news is, you don’t have to spend lots of time editing. There’s one slider built into the Photos app that will fix things up right away.
