You might misunderstand how ISO works on digital cameras. (I did.) https://www.youtube.com/watch?v=ZWSvHBG7X0w

Good grief, that video suffers the YouTube-ism of "ramble on about how you don't understand X" for way too long. Video alleges people think ISO makes the sensor "more sensitive or less sensitive". (I … don't think this is common? But IDK, maybe this is my feldspar.) (The video also quibbles that it is "ISO setting" not "ISO" … while showing shots of cameras which call it "ISO", seemingly believing that some of us bel…

Sounds like you'll be spending your day making a better video! :-)

Who said you can't capture stars in space? What do you think the purpose of Hubble, JWST, etc are? There's also plenty of imagery taken from ISS that clearly show stars. I've definitely seen Orion in some of that imagery and it put a different perspective on the size of the constellations when seen from that angle.

Photos from the moon landings don't have stars in them, because they are exposed for full daylight on the moon.

I’m assuming the people who complain that there aren’t stars are the “moon landing faked” crowd… it’s hilarious to me that they think this vast conspiracy came together to fake that whole thing, and that they literally forgot to put a bunch of tiny 25-cent flashlight bulbs up poking through the black backdrop on the sound stage. Like, no one thought about the stars, or they couldn’t figure out how to do those “special effects” and just prayed no one would spot the error.

Why didn't NASA or the news agencies rotate the image so North is up? and slightly to the right. That would make Africa instantly recognizable as that's how maps are imprinted in our brains. There is no "up" in space, so that wouldn't be editing the image I feel. The camera just happened to be oriented "upside down".

I was thinking the same thing, but then I decided to embrace the frustration of the image. It's reminding us that the pictures we have in our heads are kind of fragile. They don't prepare us for a live encounter with Earth from some random angle in space.

This is kind of profound.

I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200. Incredibly impressed at the steady hands for a sharp image at 1/4 s shutter speed though! Maybe they just let the camera float in space with the mirror up, triggering it remotely.

You can get a D5 on amazon.com. It would be amazing if one of the astronauts did a review explaining how it performs in space.

f/8 and be there?

Looking at the EXIF (with exiftool) for the image uploaded by NASA ( https://www.nasa.gov/wp-content/uploads/2026/04/art002e00019... ), apparently this was taken by a Nikon D5 with an AF-S Zoom-Nikkor 14-24mm f/2.8G ED and developed with Lightroom. It also seems like very little was done in Lightroom. Amazing... I dumped the whole EXIF here: https://gist.github.com/umgefahren/a6f555e6588a98adb74eed79d...

Wide open generally sacrifices lens sharpness.

I asked a different question in my mind, who says it "appears to us as upside down"? I would think if you lived in Patagonia, the south pole is "up".
