I did my PhD in Atomic, Molecular, and Optical (AMO) physics, and despite "optical" being part of that I realized midway that I didn't know enough about how regular cameras worked!

It didn't take very long to learn, and it turned out to be extremely important in the work I did during the early days at Waymo and later at Motional.

I wanted to pass along this fun video from several years ago that discusses HDR: https://www.youtube.com/watch?v=bkQJdaGGVM8 . It's short and fun, I recommend it to all HN readers.

Separately, if you want a more serious introduction to digital photography, I recommend the lectures by Marc Levoy from his Stanford course: https://www.youtube.com/watch?v=y7HrM-fk_Rc&list=PL8ungNrvUY... . I believe he runs his own group at Adobe now after leading a successful effort at Google making their pixel cameras the best in the industry for a couple of years. (And then everyone more-or-less caught up, just like with most tech improvements in the history of smartphones).

Try capturing fire with a non-Sony phone and a Sony phone. At least Samsung doesn't color correct blackbodies right and the flame looks nothing like reality.

Pixel camera hardware or software? Isnt there only one vendor for sensors - Sony?

  • dawidpotocki  2 days ago

    Samsung also makes sensors for phones. IIRC some Pixels use their sensors.

      I think Canon makes at least some of their sensors, and Nikon designs theirs and makes it at a third party I forget the name of that isn't Sony or Samsung but they still do use Sony stuff in a lot of their cameras.

      I don't know about Pentax, Panasonic or OMD (formerly Olympus)

    He worked mostly on the software side, but of course had important input into what sensors and processors were chosen for the phones.
