I went out on a limb today and made a bold statement.
The iPhone is not the best smartphone camera anymore. The Samsung Galaxy S10+ trumps it in several ways: it's better in low light, stabilization of video and it has three main lenses, vs. 2 on the premium iPhones.
I love the 3rd lens, the ulta-wide one. It's a little crazy and distorted, but it sure adds a lot.
Below, two normal shots, iPhone XS Max on top, Galaxy S10+ below. Both are fabulous, while the iPhone is a little warmer. Which do you prefer?
In the videos below, look at the image stabilization and the wide view of the Galaxy, vs. the iPhone.
iPhone XS Max, in the closet.
Just sayin, but if you shoot in the dark, you want the Google Pixel 3.
Ultra-wide, wide and portrait.
Most of the Samsung photo tricks are gimmicks that would be used once or twice. Software wise, iPhone wins it. Transferring of files is a breeze with the iPhone, and it's own bag of camera tricks are not just useful, but highly memorable. As in the "Long Exposure" water trick that I'm in love with, per @Chris.
But optically, sorry iPhone users, but Samsung's got a better camera. Let's hope Apple copies it big time for the fall!
