If you are ever able to make it to the KSC visitor complex in Cape Canaveral they have mock-ups of both the Gemini and earlier Mercury capsules you can get in as a size reference. They are both incredibly tight. It's amazing during Gemini 7 they spent 14 days crammed in the capsule testing systems, doing EVA activity along with normal human activity (eating, sleeping, bodily functions). All while being seconds from death at any time if things go wrong. These early astronauts were men of a different caliber.
The Todd Miller Apollo 13 documentary (which is phenomenal, it's entirely file footage but assembled better than most blockbusters) has these bits during launch/landing where they overlay the three astronaut's heart rates with the footage. My big takeaway from that was that they were incredibly unflappable, almost to an absurd degree.
Not for takeoff. Apollo astronauts used barbituates to help sleep, and scopolamine with dextroamphetamine during re-entry. Unsurprisingly the average HR during re-entry was rather higher than at launch! (source: https://space.stackexchange.com/a/31987 )
Gemini would likely have been similar, save for using Cyclizine during re-entry rather than scopolamine/dextroamphetamine.
For anybody near DFW the Apollo 7 Command Module is on display at the Frontiers of Flight museum at Dallas Love Field. Its pretty amazing to see it in person and think about the engineering involved.

No amount of computational smartphone photography can match, in my eyes, the clarity and contrast and intensity of whatever analogue medium these were captured on.
This looks gorgeous. I'm extremely tempted to splurge on this, and the Apollo, books...
Medium format film (120, 6x6), Hasselblad cameras. I personally think we're barely starting to match the quality of medium format film with modern medium format sensors
Depends on how you define quality. While medium and large format photography are extremely high resolution that’s not the only factor. Space age lenses were significantly lower resolution than the film. Modern mirrorless lenses are starting to come close to being able to out resolve film but still aren’t there. Meaning that you get more functional resolution out of modern digital. Digital also beats the pants off film for dynamic range and low light. That said the noise (grain) and dynamic range fall off in film are more pleasing than digital to most eyes. So it’s not all about technical specs.
> Digital also beats the pants off film for dynamic range and low light.
While this is true now, it took a surprisingly long time to get there. The dynamic range of professional medium format negative films is still respectable. Perhaps not so much in a low light, but it's very immune to overexposure.
Also, you can buy a cheap medium-format camera in a good condition and experience that "huge sensor" effect, but unfortunately there are no inexpensive 6x6 digital cameras.
It’s incredibly rare and specific, many people in the DB world don’t even know about them. 60x60mm sensor, larger than the actual film gate of 56x56mm There was also a version for the Rollei 6x6 6000 series, the Rollei Q16. I’ve only seen one for sale ever.
Technically larger than 6x6 film sensors have existed since the 80s or 90s at least but are typically only used for government things… Some digital aerial systems use huge sensors.
> Space age lenses were significantly lower resolution than the film.
Can you say a little more about this? Modern lenses boast about 7-elements or aspherics, but does that actually matter in prime lenses? You can get an achromat with two lenses and an apochromat with three. There have definitely been some advances in glass since the space program, like fluorite versus BK7, but I'm wholly in the dark on the nuances.
I find modern primes much sharper than their older counterparts not because of the elements or the optical design, but from the glass directly.
Sony's "run of the mill" F2/28 can take stunning pictures, for example. F1.8/55ZA is still from another world, but that thing is made to be sharp from the get go.
The same thing is also happening in corrective glasses too. My eye numbers are not changing, but the lenses I get are much higher resolution then the set I replace, every time. So that I forget that I'm wearing corrective glasses.
> I find modern primes much sharper than their older counterparts not because of the elements or the optical design, but from the glass directly
Even back in their prime, haha, the Cooke lens leaned into their glass manufacturing by calling it the Cooke Look. All of the things that gave it that look are things modern lenses would consider as issues to correct.
Actually, I'm pretty flexible when it comes to how lenses and systems behave. A lens with its unique flaws and look is equally valuable for me as a razor-sharp ultra high-fidelity lens.
All boils down what you want to achieve and what emotion you're trying to create with your photography. Film emulation has gone a long way, but emulating glass is not possible the same way (since you don't have any information about what happened to your photons in their way to your sensor), and lenses are important part of the equation, and will forever be, I think.
I wrote a longer post a few months ago.[1] The tl;dr is a) computer aided design and manufacturing b) aspherical elements c) fluorite glass d) retro focus wide angle designs and e) improved coatings. Mirrorless lenses also beat slr lenses because they are much closer to the film plane — of course rangefinders and other classic designs never had this problem to begin with.

Edit: this is just for prosumer style cameras. If you look at phone sized optics that’s a whole other ballgame.
The lenses also have to be better to compensate for the smaller sensors. All lens defects get more "magnified" the smaller the sensor is. So a straight comparison isn't fair unless the sensor is the same size as the film was.
I have the "Apollo Remastered" book and it is gorgeous. I'm going to buy this one too. Obviously they went back to the original film from the missions and did a full scan. NASA almost never gives access to the original film and instead we have been seeing duplicate transparencies which involves a loss of detail and dynamic range. They were good enough back then. But these first generation scans cannot be matched for detail and color.
You are talking about the digital, heavily processed photos here that are indeed a lot nicer than the originals taken and.printed 50 years ago. The originals were actually a bit under/over exposed (very harsh light in space), and quite grainy.
I get your point, but no amount of post processing gives my iphone 17 pro portraits the sharpness and atmosphere of what i shoot with my crappy nikon with a prime lens.
And I feel that these old analogue photos contain even more magic in the base material, digital reconstruction notwithstanding
Computational photography is about to get really good when it can combine hundreds or thousands of frames into one. 1000 frames effectively combined is equivalent to a lens and sensor of 1000x the surface area - ie exceeding a single frame from a DSLR.
Current methods use optical flow and gyroscopes to align images, but I imagine future methods to use AI to understand movement that doesn't work well for optical flow (ie. Where a specular reflection 'moves' on a wine glass).
I doubt there's enough information in more than ~4 samples to be worth fusing into one image. Maybe more if you have a full HDR display and supply chain or if the lighting is really bad, but almost everything is about having good taste in SDR tone mapping/image development otherwise.
Saying “ai” does not magically solve anything. Current best ML things can’t even solve medium difficulty calculus equations. We’re nowhere near them doing original work like understanding what’s in 1000 images, creating a world model out of that, and then rendering a better image of that world successfully without hallucinations.
I like this, it's really cool - especially the stack images from 16 mm film. The first image (first selfie in space on Gemini 12) is very artistic but I like the original better in that example - just look at the specular highlight before and after.
I understood it less as an attempt of improvement and more as an alternate version of the same shot.
Where you see more of Aldrin and other smaller bits that were less visible in the original and rightfully iconic shot.
The headline before/after image is astonishing, almost in-credible. I can't see how the left image was restored into the right. It looks like there is substantial new detail on the right that I can't see anywhere on the left.
I can only assume that the image on the left is a low resolution scan produced for this web article, and that there must be a much better scan somewhere else.
It must be. The amount of detail is incredible, and even trying to extract data from the before picture, it doesn't come close to what you see in the newly processed image.
Absolute least they did is to rescan original film with newer type of scanning process/device into higher resolution and bit depth „digital negative”. You cannot replicate that from low quality jpeg image.
I found the headline image confusing - thought it was a Sontaran (Dr. Who baddie) in there! Aldrin's face and the earth reflection are quite confusing to the eye.
The name comes from Latin "gemini" meaning "twins," referring to the mythological Dioscuri, Castor and Pollux, sons of Leda. In mythology, Pollux was immortal, Castor mortal; their story is connected with themes of brotherhood and sacrifice.
Project Gemini was NASA's second human spaceflight program (1961-1966), preceding Apollo. It developed spaceflight techniques such as orbital rendezvous and docking, essential for the Moon landing.
Gemini is also a lightweight internet protocol and associated ecosystem (the Gemini Protocol), designed as a middle ground between Gopher and the modern web (HTTP/HTTPS), emphasizing simplicity and privacy.
It is also the name of Google's multimodal AI model, successor to Bard (announced 2023).
But it is connected to the Internet protocol of the same name, which uses 1965 as its well-known port number (although IANA has not heard about this yet).

I think you mean Apollo 11, Apollo 13 was the dramatization with Tom Hanks. Both excellent movies in their own ways.
Oh drat. Yes, you're 100% correct.

Not as good as For All Mankind (the 1989 documentary) IMO! Link: https://youtu.be/JD2W4CZbH9U?si=WvdYuLnoe49_tV0l
Not to take away from their achievement, but do we know if there were drugs involved?

ISTR an astronaut saying that you didn't 'get into' a Mercury capsule, instead you 'put it on'.
Not too much different than most tactical jets, to be honest.

In fact there is basically only one digital back ever made at that size, the dicomed bigshot.
Interesting. I didn't even know that. I had to look up what's the size of the modern Hasselblad digital camera sensor, and it 43.8 × 32.9mm.
It’s incredibly rare and specific, many people in the DB world don’t even know about them. 60x60mm sensor, larger than the actual film gate of 56x56mm There was also a version for the Rollei 6x6 6000 series, the Rollei Q16. I’ve only seen one for sale ever.

finally, someone that gets it! these different lenses are all just tools. using the right tool for the job is part of being good at your job.

Film in big formats is incredible, gives great images even on shitty cameras...
These hasselblads not shitty cameras. A holga is on the other hand, and the images are shitty as a result despite being medium format.
Even the fuji medium formats don’t have sensors as large. They are more like 4cm x 3cm.

Those are medium format images. Rent a Fujifilm GFX100 if you want to try something like that. Storage space for the raws adds up though.

Great lenses with huge film frames. It's doable in digital, but not on a Smartphone or budget SLR.
I assume you've watched with delight the 2019 Apollo 11 documentary assembled from previously unused 70mm footage.

Photography and 1960s NASA. Best combo
Did they rescan the negatives for this? He mentions having access to RAW files at one point, but it's not clear.

Well that photo must have come from a negative film, which can have an astounding amount of detail, even old film.
So, what improved is probably our digitalization tools and with some post, you can reveal a lot of detail.
It must be. The amount of detail is incredible, and even trying to extract data from the before picture, it doesn't come close to what you see in the newly processed image.

Fabulous, obviously.
I found the headline image confusing - thought it was a Sontaran (Dr. Who baddie) in there! Aldrin's face and the earth reflection are quite confusing to the eye.
Anyone knows if those new photos are published on NASA images site? If they are public domain..
They're credited to NASA in the Ars Technica article, so they are likely public domain.
One of those missions lasted just shy of 14-days. Boggles the mind given the size of the Gemini capsule.
