It's a really cool discovery, but I don't know how Apple is suppose to program against it.
What surprises me is how much of a time range each photo has to work with. Enough time for Tessa to put down one arm and then the other. It's basically recording a mini-video and selecting frames from it. I wonder if turning off things like Live Photo (which retroactively starts the video a second or two before you actually press record) would force the Camera app to select from a briefer range of time.
Maybe combining facial recognition with post processing to tell the software that if it thinks it's looking at multiple copies of the same person, it needs to time-sync the sections of frames chosen for the final photo. It wouldn't be foolproof, but it would be better than nothing.
Program against it? It's a camera. Put what's on the light sensor into the file, you're done. They programmed to make this happen, by pretending that multiple images are the same image.
That’s over simplified. There’s only so much you can get on a sensor at the sizes in mobile devices. To compensate there’s A LOT of processing that goes on. Even higher end DSLR cameras are doing post processing.
Even shooting RAW like you’re suggesting involves some amount of post processing for things like lens corrections.
It’s all that post processing that allows us to have things like HDR images for example. It also allows us to compensate for various lighting and motion changes.
Mobile phone cameras are more about the software than the hardware these days
Raw files from cameras have meta data that tells raw converters the info of which color profile and lenses it's taken with, but any camera worth using professionally doesn't have any native corrections on raw files. However, in special cases as with lenses with high distortion, the raw files have a distortion profile on by default.
Correct, I was referring to RAW shot on mobile devices not a proper DSLR. That was my observations based off of using the iPhone raw and android raw formats.
This isn’t my area of expertise so if I’m wrong about that aspect too let me know! 😃
