The SLR-like cameras have a bunch of manual modes so you can 'force' them to get something captured, and you can then perhaps 'fix it in post'.

Modern tech allows more people to capture more things more easily, but when the automation fails there aren't really many manual modes to fall back on.

They did bring the Z9: https://petapixel.com/2026/04/02/a-nikon-z9-made-it-aboard-t... But yeah the grainy photo of the Earth with the D5 at ISO 51200 shows the shortcomings of the ancient DSLR. Still, great shot.

How does the age of the camera influence physics? The only thing that really helps would be increasing the aperture.

Lower noise sensors and better image stabilization for longer exposures

> I'd have probably shot it wide open at f/2.8 rather than cranking the ISO up to 51200. One of the reasons the D5 supposedly was chosen was because of its high dynamic and good low light performance. It can go up to ISO 3,280,000: * https://en.wikipedia.org/wiki/Nikon_D5 The D5 has been used on the ISS, including EVAs, since 2017, so is a known quantity: * https://en.wikipedia.org/wiki/List_of_cameras_on_the_Interna…

The good low light performance was amazing for its time (10 years ago), and it still holds up decently today. But let's not kid ourselves -- it has been clearly surpassed by modern backside illuminated CMOS sensors like the one on the Z9. EDIT: sorry, it seems I'm wrong. I just checked https://www.photonstophotos.net/Charts/PDR.htm and while the Z9 has the clear edge with 2 more stops of dynamic range at low ISO, the…

Sure, but D5s were also doing EVAs for many years and much more of a know quantity in space.

https://www.reddit.com/r/3DS/comments/1sakb3v/artemis_ii_lau... The launch, shot on a Nintendo 3DS. For those with a gen z-like retro tech streak.

What a mad idea.

The aesthetic ended up pretty cool but I can’t imagine the thought process that lead to capturing the launch on a 3DS.

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...

It's fun to think about tile dilation per the exif captured Create Date: "2026:04:03 00:27:39.26". I know it's negligible over the trip, but when they took it, was their time really "2026:04:03 00:27:39.25"?

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…

ISO changes the analog gain and in a way yes, it does make it more sensitive to a certain range of brightness . This is because the ADC (analog to digital converter) right after can only handle so many bits of data (like 12-16ish in consumer cameras). You want to “center” the data “spread” so when the “ends” get cut off, it’s not so bad. Adjusting the ISO moves this spread around. In addition, even if you had an infi…

Technically correct, the best kind of correct. After all, the moon is in Earth's orbit.

One would hope they’re still in Earth’s orbit - if they’ve achieved escape velocity they’re not coming back.

So if we’re being technical I think they did achieve escape velocity? But the moon’s gravity and some timed burns will slingshot them back.

You have to wonder how unserious this can get. Given the unimaginable cost of this mission, they are faffing around as your typical aunt with Windows Home laptops and iPhones? Seriously?

This is exactly what newbies experience when trying to photograph the moon from Earth. It's not intuitively obvious, but the light coming off the moon is essentially full-daylight bright. But the moon is small against a very black background, and depending on how the auto-exposure is operating, this often leads to guessing that the scene as a whole needs a lot more exposure.

I imagine that trying to photograph the Earth when a significant part of what's in view is experiencing daytime, is very much the same thing.
