00:00One of the fundamental pillars of photography is aperture.
00:03It controls how much light enters a system and affects every photo and video you take.
00:09Being able to change the aperture provides more control for light intake and depth of field.
00:15So iPhone 18 Pro has a new 48 megapixel Fusion main camera with variable aperture for creative control that wasn't
00:24possible before.
00:26This is the most advanced camera we've ever made.
00:30To create variable aperture, we developed a system of six laser-cut blades, each thinner than a human hair.
00:37The blades are made of a specialized polymer composite for the right balance of mass, flexibility, and durability.
00:45There's a new rotor mechanism to control movements and a custom-designed lens to ensure image quality at multiple apertures.
00:53The aperture adjusts automatically based on the scene.
00:57When you're in a darker environment, the aperture opens to let in around 50% more light, like in this
01:04portrait with impressive detail and color range.
01:07Night mode captures are faster with better quality, like this astrophotography shot.
01:14This was shot at f1.8, an aperture we've optimized for the best balance of light gathering and depth of
01:22field.
01:22And the aperture can narrow for more depth of field, which means crisper detail further back in the scene for
01:29better group shots.
01:30This new camera is paired with intelligent camera software to do even more.
