Aside from all else, the first image was taken on film lit by daylight, the second was shot on digital at high ISO lit by moonlight with a little sunlight at one edge

Moonlight doesn't have the same colour rendering quality as sunlight

[–] Vorticity@lemmy.world 2 points 3 days ago (2 children)

Thanks for the info, that's awesome! Based on the quality of the image, I'd guess this was a specialized camera designed to have a broader range of sensitivity. Do you know if that's right or did they just use a nice DSLR?

Also, the first image has been corrected for rayleigh scattering, either algorithmically or artistically. The second image does not appear to have been corrected. It looks similar to what we get from geostationary satellites prior to performing rayleigh scattering correction.

There is a much higher quality version of the second image on NASA's website. I think the reason the second image has so much colour ranges because it was taken in log, but that's just a normal SLR camera feature. I think there's even a way of getting my phone to take pictures in log, it just uses a lot of memory so it's not on by default

[–] psud@aussie.zone 1 points 1 day ago

Log? Isn't that the video thing? Still images use raw for best post processing

[–] Obi@sopuli.xyz 1 points 3 days ago (1 children)

It's a Nikon D5, the shot is at 52k ISO.

[–] Vorticity@lemmy.world 1 points 3 days ago

Cool, thanks! That's some crazy high ISO.

[–] Blackmist@feddit.uk 78 points 4 days ago

No wonder it feels more crowded

[–] Taleya@aussie.zone 4 points 3 days ago

Completely different landmasses as well!

Kubrick, we're onto you

Well that’s what happens when you leave it out in the sun

This helps explain why days seem shorter as we age, the Earth is spinning faster due to the conservation of angular momentum. The days are literally shorter.

[–] sga@piefed.social 7 points 4 days ago (2 children)

fun fact, days have actually been getting longer pretty much since formation of earth (well moon to be correct). reason iirc is that moon is slowly moving away from earth, and this results in some dynamics changing and as a result earth spins slower. like billions of years ago, it was closer to 23 hours.

ps - very rusty memory right now, should have skipped writing instead of half borked fact

By the way, speaking of changed colours of planets: if you haven't been keeping up with the latest news in space imagery and want a real mindbender, check out what has recently happened to Neptune. You may have been thinking, ooooh, what an enthralling blue planet! - bzzzzzt, turns out it's a pretty bland and boring gas giant, the colours were exaggerated on purpose because otherwise you can't see shit.

[–] TheOakTree@lemmy.zip 6 points 4 days ago

I like the pale blue representation, reminds me of blue jade or some old seaglass.

[–] MajorMajormajormajor@lemmy.ca 5 points 4 days ago (1 children)

This truly is the worst timeline. Next, they'll tell us Uranus isn't gassy too.

[–] NigelFrobisher@aussie.zone 3 points 4 days ago

Nah, it is. Just checked.

Most ~~planets~~ galaxies are like this I believe

[–] Vupware@lemmy.zip 2 points 4 days ago

Nebulae especially.

[–] pineapplelover@lemmy.dbzer0.com 24 points 4 days ago (1 children)

Second picture looks smogier and more polluted

[–] PoopingCough@lemmy.world 36 points 4 days ago* (last edited 4 days ago) (1 children)

Well the second pic is also at night with a high iso and long exposure plus it's digiral so there's a lot more noise going on.

[–] IMALlama@lemmy.world 6 points 4 days ago (1 children)

Speaking in generic terms, film is way more forgiving of over exposure and digital is way more forgiving of under exposure. A fast lens is always king, but once you hit parity on that I would personally take digital for low light any day.

The maps were correct, New Zealand doesn’t exist.

[–] altphoto@lemmy.today 18 points 4 days ago (2 children)

I like how you can see the ring/sphere of atmosphere in the new image.

[–] nosuchanon@lemmy.world 15 points 4 days ago (3 children)

That’s the new smog layer.

To be fair there was a big hole in the ozone in 1970

It's because the Sun is behind it.

[–] postscarce@lemmy.dbzer0.com 6 points 4 days ago

Proof that global warming is not real!!!! Read your science… if something gets HOTTER it EXPANDS!!! Those scientist cucks have cucked themselves good this time!!!!

/s (in case it’s needed)

[–] kossa@feddit.org 2 points 3 days ago (2 children)

It's because the Apollo mission photos were obviously faked. How would they have known how small Earth really is, duh!

The magnetic poles must be moving substantially. Africa has rotated almost 90 degrees in a few short decades!

Also looks much more sickly (yes, its because they pumped up the brightness lol)

[–] Tollana1234567@lemmy.today 1 points 3 days ago (2 children)

with higher gravity it might shrink.

[–] Hadriscus@jlai.lu 3 points 3 days ago

Best I can do is more gravitas in my Lemmy comments. not sure it's enough for the planet to collapse but I can try, if there's a chance of it ending our current conundrum

[–] Venat0r@lemmy.world 1 points 2 days ago

with shrinking it might higher gravity too

[–] Blackfeathr@lemmy.world 8 points 4 days ago

Where did Africa go?? 😧

[–] resipsaloquitur@lemmy.world 4 points 4 days ago

Big if true.

[–] mavu@discuss.tchncs.de 2 points 4 days ago

continents seem to have moved too.. weird.

[–] ParlimentOfDoom@piefed.zip 5 points 4 days ago (4 children)

It's because we're looking at a different side of the planet in the second photo.

Plus, that 2d image makes it look flat, like a penny.

A lot less green, as well.

Jerryyyy, Earth is a planet!
