This image of home just came down from the Artemis II crew.

Taken after their translunar injection burn, there are aurorae at top right and lower left, and zodiacal light at lower right.

    AFAIK anything past 32,000 is digitally expanded (which could be done with RAW post-processing).

    My 2015 Sony a7s2 has β€œnative” iso to 102400, and expanded to 409600, but it was a special full frame low light sensor and it’s only 12MP (most from back then were 20-30MP with the same sized sensor.

    From Wikipedia:

    For still images, the Ξ±7S II's ISO is 100–102400 with expansion down to ISO 50 and up to ISO 409600 equivalent. For movies, the Ξ±7S II's ISO is 100-102400 equivalent with expansion down to ISO 100 and up to ISO 409600 equivalent. For still images or movies on auto setting, the camera's ISO is 100–12800 with selectable lower and upper limits.[2]

    This makes me want to cry.

    I try to be stoic and harden my heart to defend it from the horrors of the world and current events, but this is just so beautiful and amazing and all I ever wanted since I was a kid.

    I don't know how people can look at this and be unable to pause and just want peace. We are so small and fragile.

    We as a species should be working together, not trying to kill each other at every possible moment.

    It's all I've ever wanted, and as I've aged I've become jaded and felt it's just been a stupid dream. But seeing this picture reminds me of that feeling, a world without borders.

    Thank you NASA.

    The photo's metadata reveals it was taken with a Nikon D5, focal length: 22mm, aperture: f/4, and exposure time: 1/4 sec.

    They should have brought a brighter lens, heh.

    Good morning right back at you! 🌍✨ What a breathtaking way to start the dayβ€”those new high-resolution views of Earth from the Orion capsule during Artemis II are absolutely stunning. The crew (Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen) is well on their way after yesterday's launch, capturing our planet as a glowing crescent against the void of space from tens of thousands of miles out. It's the first time humans have seen (and shared) this perspective since the Apollo era. Here are some of the spectacular images making the rounds from NASA's releases and the mission:


    How the hell is the window edge BEHIND the Earth?


    Why is the image so grainy for? Is this ai?


    Why does NASA keep posting these perfect round pictures of earth while according to science the earth is a spheroid?

    Anyone know if the grain is due to radiation or just ISO?

    This is on the night side of Earth, so lit only by moonlight. It’s grain from long exposure high ISO - thanks for the correction.

    Wouldn't a long exposure have less grain? Usually it's short exposure and high ISO that results in grain.

  • [–] 3 points 7 months ago (2 children)

    Less grain than a shorter exposure? Absolutely. Due to motion you still have to cap exposure duration to a somewhat small number or you'll start getting light streaking. It would be very interesting to see the exif information for this photo.

    Thanks! I should have looked.

    ISO 51,200 is pretty high, which is why there's the grain/noise. I wonder if whomever took the photo also tried with a somewhat longer shutter speed and/or wider aperture. Both would reduce ISO and thus noise but come with trade-offs. Longer shutter speed can result in light streaks due to motion and a wider aperture will give less depth of field.

  • source

    it is the high iso that produces the visible grain.

    long exposure time would have less grain, but to use it, you need for the scene to not move long enough.

    the movement and subsequent blurred image is introduced by two different things. either the scene itself is moving, or it is the camera that is moving (your shaky hand, or the spaceship doing 20000+ km/h.

    if the scene is not moving and you can use tripod to stabilize the camera movement, then you can use long exposure time and however low iso you want.

    if this is impossible, because tripod in a spaceship would still not help shaking the camera relative to phographed object that is outside of the spaceship, then short exposure time (and high iso to compensate for that) is your only choice. (and still, even with the super high iso, it still was 1/4s. i suspect some stabilization in the lens.)

    They left the EXIF data in the file, you can see the huge ISO. Really interesting lens also.

    EDIT: I've now seen this is actually the night side, so it checks out.

    This is full of interesting but slightly puzzling information.

    First, it's shot at 22mm, which is a pretty wide angle, so I guess they were still pretty close when they took it.

    What's really puzzling to me though, is why did they need to crank up the exposure so much?

    We're looking at 51k ISO @ f4, I can shoot in really dark places with this kind of ISO (but I don't, because it looks like trash).

    They seem to be shooting the day side of earth as far as I can tell, so I don't really understand why they needed that much sensitivity, instinctively I would've assumed you'd only need the same kind of settings you'd use on daytime exteriors here on earth (so nowhere near that ISO).
