Default 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

apple is *not* heavily restricted with hardware.

the future is computational photography, where what was once considered
impossible is now trivial to do.

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.

yes I know I've been using it for years but not with a still camera with a
webcam connected to a computer and it was the software on the computer that
made it possible it wasn't the camera.


no you don't know. i was talking about still cameras, which have had it
for ~20 years.

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.

which still cameras have had this for 20 years ?


olympus had it 20 years ago but i don't remember the model name. others
did since then. it's trivial to do.

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 do you mean by depth map ?

They haven't


yes they have.
