In the past we used CCD camera sensors. Those take the whole picture at the same time. Then CMOS replaced CCD, and they can no longer capture fast moving objects correctly
I said "space", and I would think that every application in that sector is already in that "extremely-high-level".
Truth be told, I was thinking satellites. Given how CCD sensors behave against space radiation enviroment compared to CMOS ones (even if they're are catching up), not to mention the inertia of the space sector, and plenty of other considerations such as RTS noise, etc. you can still find CCDs here and there, when, like you said, consumers basically don't have access to them since a huge while (especially for power consumption reasons).
CCD is on a heavy decline though. CMOS sensors are all the rage right now in the space segment, way cheaper, less crosstalk, more flexible in their use and actually less noisy now. Although, yeah RTS is a real pain to deal with!
I can't really say it here, I guess it'll be the same for the others in this thread. Not because I've worked on anything really sensitive (I didn't) but space tech companies dislike their employees speaking "in their name" outside of official channels, like in many sectors :)

Nah. I've put $30 camera modules meant for Raspberry Pis on spacecraft. Sometimes you just need something that'll live through launch so you can confirm everything looks good.
I worked on the world's biggest CCD for the Vera Rubin observatory (LSST). The sensor area is about 1 square meter
It was about $100k for a single one of the 189 sensors that made up the mosaic. Each one was, I believe, 16 megapixel, making the entire sensor about 3 gigapixel. Crazy stuff
I never saw the camera put together (my work was over 10 years ago at this point), but I worked on characterization of the CCDs, did QE (quantum efficiency) and dark current analysis
I went to school for math and comp sci, and ended up doing a summer internship through the US Department of Energy at one of the national labs.
I just ended up never leaving, I guess. Computer science is a solid way to get into a lot of other science disciplines, since you basically can't do any science these days without computation. Currently working in nuclear and particle physics, but I myself am not a physicist
That reminds me. Everyone has blurry pictures of Bigfoot. But what if IRL Bigfoot is just blurry? Like I think we have a blurry saskwatch just walking around.
Yeah photography is not very big in the alien art world anyhow. Even if you DID get a good photograph the only people who want it don't have much money or are a government agency and they don't pay for shit.

How ? Is it the shutter speed ?
Edit : thanks all for the answers, learned so much on digital cameras and lighting. Fascinating stuff
