The IPPA awards celebrate the best photography around the world shot on an iPhone or iPad.
The photos must also not be edited with any desktop software like Photoshop - which makes the winners’ stunning works seem even more impressive.
There were 18 categories, and awards for first, second and third place.
Here are some of the winning shots.
