原來XS個camera係咁堅
"TL;DR: iPhone XS is unique in that it's the
first iPhone to rely heavily on computational photography. The result is that it tends to shoot more photos at faster shutter speeds and with higher ISO sensitivity, which lead to a bit more noise. This, coupled with the noise on iPhone XS sensors being a bit more noticeable, leads the the 'skin smoothing' effect when it applies noise reduction.
In RAW photography, the camera still optimizes for this style of shooting, which gives noisier and worse exposures overall. With an adjusted version of our app, however, we were able to properly utilize the new sensor technology and get better shots than an iPhone X ever could."

"What’s this about a ‘soft filter’ on my selfies?
It doesn’t exist. I don’t want to say that some people make up controversies to get Youtube impressions, but you do have to take things on the internet with a grain of salt."
