Apple and computational photography
So with the new iPhone XS, the cameras on the back has received a number of
hardware updates, while most of the progress they're making is in software. And it's no wonder, really. They're heavily restricted when it comes to the hardware so any innovation needs to be on the software side. Two years ago they presented the "Portrait mode" where they used both lenses to create a 3D map of the scene and blur the background in post automatically, faking a short focusing distance. generally it works really well. This time around they even give the user control over this process, and using a slider, you can change the aperture size in post, seeing the background come into focus or blend away. They've also increased their number of exposures when you take a picture, in order to render a more detailed HDR photo -- Sandman |

Which doesn't actually mean much, I've been waaiting for the pre exposure thimng for years and it's only just happened in the photogrphy world. that's been around for ~20 years. I;ve said for a long time that one thing a smartphone camera can't do is have aperature control. They still can't but they can fake it to some extent. if you mean more than one f/stop, that exists too. however, that's hardware, not software. |

So all smartphones are limited, how long has it taken for smartphones to be able to change the aperature, we've had this on cameras for 100+ years. everything is limited, especially 100 year old film cameras. what kind of depth map did you get with it? What diffence does it make whether it's software or hardware as every company has the same problem(s) which havenlt been overcome yet. they have been. |

So all smartphones are limited, how long has it taken for smartphones to be able to change the aperature, we've had this on cameras for 100+ years. everything is limited, especially 100 year old film cameras. yes but they weren't all limited to just one aperture. Smartphones have been about for nearly 10 years and the cameras apps are just getting apertures. so what? smartphones take better photos than 100 year old film cameras. they take better photos than most film cameras for that matter. digital cameras can adjust focus and depth of field *after* taking the picture, something film cameras can't ever do. what kind of depth map did you get with it? What do you mean by depth map ? https://en.wikipedia.org/wiki/Depth_map What diffence does it make whether it's software or hardware as every company has the same problem(s) which havenlt been overcome yet. they have been. They haven't yes they have. |
