How ? Is it the shutter speed ?

Edit : thanks all for the answers, learned so much on digital cameras and lighting. Fascinating stuff

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

Sounds like a scheme from big space to keep us from photographing aliens.

u/edparadox 21d ago

Funnily enough, the space sector still uses CCD technology.

u/theBarneyBus 21d ago edited 21d ago

Edit: I guess I should clarify, I’m talking Astrophotography cameras (photos through telescopes from earth). Cameras in space are still mostly CCD.

Extremely-high-level cameras maybe, but anything any consumer would use is now CMOS.

You’re talking 100k+ for your setup/observatory before a CCD camera starts making sense.

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).

Edit: Same source, BTW.

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!

Same source :)

ya'll could be coworkers and not even know.

u/Jasper1296 21d ago

You guys seem to have cool sources! If I may ask, where do you work? Seems very interesting

u/Minerraria 21d ago

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 :)

u/Jasper1296 21d ago

Totally get it! No problem, was already thinking it would be something like that, cool anyway!

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.

u/Vinez_Initez 21d ago

That is not true, most scientific cameras are CCD.

8

u/tricularia 21d ago

Does this apply to modern stand-alone digital cameras as well? Or are you just talking about cell phone cameras?

8

u/thegreybill 21d ago

Yes. Most modern cameras use variations of CMOS sensors.

u/ProcyonHabilis 21d ago

Yeah none of your basic, garden variety consumer satellites are going to use it.

u/Ninja_Wrangler 20d ago

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

u/theBarneyBus 20d ago

Woah. Definitely going to have to learn a little about the place. Thanks for sharing.

How does one even get into that type of work? I’d assume some sort of engineering?

1

u/Ninja_Wrangler 20d ago

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

u/Buck_Thorn 21d ago

See? There's the proof. We get CMOS and they get CCD.

u/Missuspicklecopter 21d ago

I got fired from the Space Sector for asking too many questions. 

About klingons

I just watched an episode of What we do in the Shadows where there were 3 vampires called, Neil, Patrick and Harris.

Any more of those posts and they gonna mod you on r/aliens

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.

u/_bazinga_x 21d ago

bigfoot is originally from japan and they look like that because theyre naked

u/Mace_Thunderspear 21d ago

What if nobody shot JFK and his head just did that on it's own?

u/inactiveuser247 20d ago

It happens. In fact, that’s happened to me last week. I was just driving through Dallas and bam! My head exploded and blood went everywhere.

u/Soddington 21d ago

That used to be a Mitch Hedberg joke.

It still is, but it also used to be.

u/Franklin_le_Tanklin 21d ago

Rip In peace my guy!

u/luciaes 21d ago

That's extra scary

There's a large out of focus monster roaming the countryside...

u/Appropriate_Joke_741 21d ago

I think big foot is involved too to prevent photos of the big fella

u/pzycho 21d ago

Big Space? Big Foot? I'm starting to see the Big Picture

u/Ok-Dragonfruit-5479 21d ago

I will never not chuckle any time that 'big' is used in this way...big cereal, big space, etc. gets me 10/10 times

u/_Beets_By_Dwight_ 21d ago

If anyone in New Jersey had a Nokia we'd know what was really up with those 'drones'

u/GobbleGobbleChew 21d ago

Most likely techno-necromancers from Alpha Centauri!

u/tricularia 21d ago

We can still photograph the aliens that rotate slowly, I think

u/paul_gnourt 21d ago

Big Space strikes again smh

u/bobbymcpresscot 21d ago

Fun fact for anyone curious CMOS sensors were developed for NASA during the space race.

u/JoeyJoeJoeShabadooSr 21d ago

This is peak big space

u/AlienArtFirm 21d ago

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.

u/16incheslong 21d ago

aliens being extremely fast is a misconception . we totally arent
