The iPhone X’s camera has been put to the test in several different scenarios so far. Adding to that list is a new review from photographer Austin Mann, who took the iPhone X on a trip through Guatemala. Tim Cook shared Mann’s review in a tweet this evening, calling the pictures he captured “sunning.”

Mann’s review goes pretty in-depth, offering shots in low-light and various other environments. One improvement he specifically notes of is optical image stabilization on both the wide lens and telephoto lens:

The photographer also tested the new support Portrait Mode with the front-facing camera. He explained that in a low-light environment, the front camera is much better for portrait mode because of the infrared technology it uses:

The iPhone X telephoto lens is now also equipped with Optical Image Stabilization (on the 8 Plus, only the wide lens is stabilized). This means less camera shake and better low light performance as well.

While shooting with the telephoto lens in other low light settings, I found less noise, faster auto-focus (especially with Portrait Mode), and faster shutter speeds (reducing motion blur).

Aside from camera technology, Mann points to a few other changes that make the iPhone X a killer pocket camera. He says the smaller form factor of the device makes shooting one-handed a breeze, while he also notes that the OLED makes shooting in direct sunlight a lot easier:

Sometimes it can be challenging to see the iPhone screen while shooting in super bright environments, but I found it much easier to shoot in direct sunlight compared to the iPhone 8 Plus thanks to the brightness and contrast of this screen.’

Love the amazing photos we’re seeing from iPhone X users! Check out this stunning work by @Austinmann #ShotoniPhone https://t.co/L1XTZrdHnl
