The popular camera app, Halide, has researched and tested the camera's in the iPhone XS and iPhone XS Max. In short, they have discovered that the new camera's make a big difference with the previous generation of iPhone cameras.
Halide's team confirms Apple's marketing that the new camera systems in the iPhone XS and iPhone XS Max put them in the new era of 'computational photography & # 39; bring. It is less about the hardware and more about how the software benefits from the hardware.
In particular, with the ongoing beauty filter Debacle, Halide says this is due to "better and more aggressive noise reduction and merged exposures that reduce sharpness by eliminating sharp light / dark contrasts."
For the latter it is important to understand how our brains perceive sharpness and how artists can make things look sharper.
It does not work like those comical CSI shows where detectives scream & # 39; improve & # 39; on a screen. You can not add details that have been lost. But you can fool your brain by adding small contrast-rich areas.
Put simply, the iPhone XS combines exposures and reduces brightness in brighter areas and reduces darkness in shadows. All details are still there, but the human eye sees it as less sharp because of local contrast.
According to Halide this also extends beyond skin tones. Photos with subjects in the dark – whether it is cats or wood grain – also receive this so-called flattening. Simply put, iPhone XS has a more aggressive noise reduction than previous models.
Halide believes that iPhone XS prefers higher ISO and shorter shutter speeds, resulting in faster photo 's, but higher noise.
To combat this, the new Smart HDR feature from iOS makes different photos and sews them together, achieving aggressive noise reduction. This also shows a loss in some detail and local contrast.
This is most evident in selfies, where most are shot behind really hard lighting, like the sun. Selfies are no longer blown out, but your photos become smoother and less detailed.
