Your vids are always so interesting, thank you! :]
Your eyeball IS technically your brain. So i think persistence of vision is due to both. But im no expert
I'm in the process of adjusting which creators I support, and increasing how much I support those that I can, and I feel a little badly that I haven't become a patron before now. I am hoping (and probably will) add you to my list, but part of my new model is to focus on creators that support alternative sites to KZhead. Is there any reason that you would be opposed to mirroring content to somewhere like Odyssee? I watch a lot of KZhead creators there, and I was a little surprised to not find you.
Destin, please don't ever loose your child like glee at learning new things and solving puzzles! It's infectious! Thanks! :D
I don't do speeling corrections, but KamerStore... They really deserve KameraStore
Thanks for visiting us in Finland, Destin! We were happy to show you the lovely Finnish summer and what we do to keep film cameras alive. These machines deserve love and we're happy to provide it. (-: - Connor
It is wonderful to see you preserving all those incredible machines.
Was like.. is that Finnish guy speaking English and apparently yes. So Torille! :D
Gotta pop in next week :)
I didn't expect this kind of collab
For some strange reason I've never heard of you before. I love what you guys are doing and I will share this video with my photography friends, of whom I have many. Greetings from Norway!
The hype I feel when I see that *Destin* just dropped a video about a machine that I never even considered needed to exist.
It’s Destin but yeah
Totally
For what it’s worth: I believe the vast majority of the machines in the world are ones which you had no idea they needed to exist.
I know exactly what you mean!
For what it is worth, I feel the same excitement about this thing
As a german it was really interesting reading those pages. Thank you for the insight in this old technology. To figure out all of that mechanically must have been stressful! :)
Yuno c: Yes, but _endlessly_ fascinating.
😀 Totally agree! (Stimme dir zu)
It is the physical expression of mathematics, there was more coupling of physics, math, and engineering in those days.
I worked for a german company for 12 years and I loved!. I loved the philosofy of "fail safe" and then an american corporation destroyed it. It is a petty, because I love the West, the freedom we used to have and the things made for ever. Now i have an old radio repair shop... to survive. The profit alone is not good.
@@soulrobotics bless you internaut. irgendwann kommen immer bessere zeiten. Habe hier ein altes Nordmende Fidelio stehen. Klingt noch 1a.
I never even questioned how to mechanically measure milliseconds before. I never even knew that those circles on record players had a function. These are best types of videos to go with morning coffee on a day off work. Waking up to learning something I didn't know I needed to learn.
I remember watching those markings on the side of the player, kind of mesmerized by them. Never knew what they were for!
Thank you so much for the visit Destin! I am amazed how your drill happened to have the right spinning ratio for the Ketchuponator 3000 to be so close to the real thing! - Juho
Hienoa työtä, mahtava video! Pitääpä joskus käydä tutustumassa teidän liikkeeseen kun olen Tampereella.

@@motosk8er2 yes yes but... to match so closely... i know its all maths but has he just winged it or did he sharpied his calculatron-o-meter.
As a film photographer, I cant tell you how long I've been waiting for an answer as to how camera shutters were calibrated before the modern age! Thanks Destin- Great video as always!! :)
An age where machines could be timed to the millisecond IS the modern age. All that's happened since then is electronics. The early 20th century was an orgy of technology and technological progress. People were flying, for crying out loud. Across continents. It's funny that people have forgotten how far out it was that homo sapiens had started fricking flying. The first half of the 20th century was Very Very Modern. We're now in the post modern era where just writing code creates god powers.
I always wondered that too. And it was really interesting.
Those Germans never cease to amaze and remember that Lieca was doing ground breaking work, this was new territory and absolutely amazing.
Sadly, they already did cease. There has been no significant innovation in Germany for at least 20 years, now.
@@elmariachi5133 thanks to the retarded immigrants ruining our country, I doubt we will get more powerful again in the future either...
Yikes what a wrong statement
@@Pilzmann it's true
@@elmariachi5133 Not only Germany, the whole world has sort is stagnated. Yes, we are making better and better iterations of screens, radios, photovoltaic cells, etc. But when it comes to a truly new zero day exploit we haven’t found it yet. New breakthroughs in physics have to occur for truly new technologies to arise!
5:13 for the interested people here. The translation of the top part in the manual: Adjustment and check of shutter speed Continuation of page 14 The slit shape of the shutter needs to be wider on the lower frame edge compared to the top. The drum images (see Abb.19.1) show the progression. If the spring cylinder of the first shutter curtain is tightened then the slit shape on the bottom will be widened, if released it will be narrowed. Images of [Abb.19.1]
I never even considered how one would calibrate mechanical shutter speed. Totally blew my mind -- thanks Destin!
You could use a standard light and film developing time and compare the brightness but it is very fiddly and hard to get right.
Brian - as a diver taking underwater photos before the GoPros were available, we had to guess at mechanical shutter speeds and boy could you waste a ton of 35mm film before one came out even using U/W strobes and light systems. Destin gets into some things that are buried in my wheelhouse, that's for sure.
From the first thing Ari said, I identified him as Finnish, the accent of Finns talking English is so distinct. Greetings from Tampere!
Yes one of my favorite accents, up there with northern Irish accent
the finnish-english accent is so distinct from others that it's hard to miss once you know what you are looking for
@@skyefarnan2311 Can’t say I’ve ever heard anyone say they enjoy the Finnish accent. Nice to know there are fans out there.
One of the things I've always noticed is that Finnish men have very deep voices. Unrelated to this clip, I've met many Finnish men who can drink a lot.
@@PeperazziTube We don’t have much else to do here haha.
I love that your excitement and sense of wonder at this amazing technique comes through on film. I really like learning about all the fantastic stuff on your channel, but your awe, wonder and open excitement is my favourite part. Thanks for being you Destin.
Enthusiasm is contagious and learning is the most enjoyable human activity. This is great. Also, years of watching F1 told me IMMEDIATELY that we were in Finland.

At least half of the enjoyment i get from watching SED-Videos is not the information itself but to watch the neverending excitement of Destin while discovering new things. Very wholesome.
I wish he would've gone more into the effect being utilized here (persistence of vision)!
He could call a series SED Talks!
Heh, growing up in east germany, SED Video or SED talks is a funny name to me for sure.
@@Haldjas_ Guter Punkt :D
I have almost no interest in film photography, and even I can't help but get excited whenever you post a video on this topic. Amazing presentation, as always! Thank you for sharing this with us!
This was a really interesting video, Destin! I now want to repair cameras in Finland...Thanks Patrons for helping him make this!
As an electrical engineer I'm always amazed by how many problems can be fixed with mechanics and in what smart ways...
Fun fact: This is also how turbo-prop engines are balanced to their propellers, very similar tech :D
you remember, that these old engineers where able to sync machine-guns with the propellers? So the gun would fire through the gaps - not the best use-case - but stunning anyway. 😲
@@ThorDyrden yeah I think the trigger was activated by the timing gear so there was physically no possible way for the pilot to accidentally cause it to hit the prop
@@ThorDyrden Another fun fact: Those guns that were set up to fire through the propeller weren’t actually running in full-auto mode. They were set to semi-auto, one shot per trigger pull. But as BreadLoafBrad said, the engine was pulling the trigger so it was still quite fast. The split-second timing required for this also required using guns that fired from a closed bolt, like the Browning machine guns and various Maxim derivatives, such as the Vickers MG. Open bolt designs like the Lewis have cycle times too variable for reliable synchronization. That’s why the WW1 era fighters that used the Lewis had them mounted to the top of the upper wing, firing over the prop. (/gun nerd)
@@breadloafbrad wow thats crazy, they had the gun shoot and the bullet would travel through the gaps of a spinning propeller? i had no idea
Great video and very well explained! We've still got some of these devices in our workshops 😉
Awesome!
Are you working on a new film camera?
Your raw energy and enthusiasm to all these subjects is really contagious. I love watching every new video
This was an absolutely brilliant demonstration - the additive photo showing the stripes with the rolling shutter in slo mo just made it make so much sense!
I was the proud owner of a brand new Leica M4 camera many years ago and my dealer (I was living in Germany at the time) arranged for me to attend the Leica School, that included a complete tour of the factory. Although I don't specifically remember this test instrument, I am sure they showed it to us at some point. I was happy to see the Leica "guts" that they gave you to play with, as it reminded me of my now long gone camera. This was one of the best cameras I've ever owned. I'm glad there are people like the ones in Finland who are still appreciating these units and restoring them for people to use today. Thanks for another thoroughly interesting piece.
Your ability to make us feel your passion about things that we didn’t even know existed before we clicked on the video is amazing! Thank you for everything you’ve introduced to all of us to. I love you so much!!
I noticed you could see the holes in the peg board (I think) when he does the slow mo on the camera initially.
If you bought a camera from KameraStore.com/smarter I’d love to know what you got.
Haha I've bought a few cameras AND lenses from there. Fast and reasonably priced shipping to Australia!
Over the years, I have bought many equipment from them, including a Nikkor 180mm f/2.8, Distagon 28mm f/2 and several rolls of film.
Got a vintage lens from them last year. Great experience, lens works perfectly. It's a 135/2.5, very nice lens 🙂
I've bought lenses from them. Got a Mamiya C330 body in Mexico back in november, really cheap, 50 bucks but the lenses for that TLR... I ordered them from KameraStore because I knew they would be tested and would be shipped in a perfect way. Thanks KameraStore and thanks Destin!
Well I do feel a little smarter now 😂, nice one Dustin
As a german, I'm kinda proud about all the stuff we invented in the past. I just love the mechanical engineering behind this.
Hey, not trying to be rude, but I'm curious: Why do you feel any kind of kinship with the people who invented this? The only thing we both have in common with the people who invented this is our nationality and it's not like being German gives us some sort of higher power that allowed those people to invent these machines. So I don't really understand this whole thing about being proud that you happen to have been born in the same country as the inventors and scientists that came before.
@@gownerjones1450Is that not enough, being proud of what someone else who lived in the same country as you has invented. If your brother or someone you've gone to school with accomplishes something great, wouldn't you feel proud to have gone to the same school as that guy or lived in the same house? Its something that connects you to that person
@@gownerjones1450 Why are Americans proud of being Americans? It's the same thing. Basically you can't be proud of something you haven't achieved, but was simply given. But still people (no matter which nationality) tend to be proud of being part of a social group, no matter if it's an achievement or not. Or being proud of "your" football team that has won a match, although you are not part of the team at all. It's the feeling of being part of social group that is better than other groups. I guess that's an evolutionary thing. By the way, the whole professional sports thing is living from this phenomena. People identify themselves with their team as if they're part of the team, and feeling superiority over others when their team wins.
@@gownerjones1450listen clown, we are allowed to be proud of our ancestors and our nationality. I’m tired of the constant demoralizing.
@@mickeyslaven Looks like I struck a chord with you. I think my country is the best country in the world. How is that demoralizing? I just think pride is a weird emotion to feel about being a nationality, or for a complete stranger's achievements. If you feel demoralized because I have a slightly different opinion than you, you probably need to visit a mental hospital.
As an amateur photographer, I am always wondering why a film camera can act a millisecond-timescale shot, and how to caliberate the mechanical shutter. This video answers all the questions. It's amazing and fascinating that people developed those techniques in 1930s. Thanks for your informative video. I'm so happy to be smarter today!
During the 20s and 30s, most of our machines were imagined or being developed. Normal people take about a hundred years to understand mathematical concepts and apply them. We aren't stupid but there has to be a utility.
I think the shutter of a film slr and digital slr still works in the same principle. If you set it 1/200 of a second, the film will be exposed to light only on 1/200th of a second, which is the same with a digital sensor
Wow, We both visited the Kamerastore in Finland ! What an amazing place !
I absolutely love all the photography/film focused videos you've been doing!
Thanks for this video! I just got into analog photography and it's so fascinating, how they made these high precision machines back in the day, completely mechanical. Thanks to @Kamerastore for keeping this wonderful craft alive!
Love the video Destin, especially your at home recreation with the ketchup bottle. By the way, it was interesting to see a TI-84 CE calculator on your desk. The CE model was released in 2015 as an effective continuation of the TI 81 series (which went through 82/83/83+/84+ branding with various upgrades), all of which used the same processor, the Zilog Z80 that was released as a consumer chip in 1976. The CE is the first model in the line to get a new processor, the eZ80 that was released in 2001. So TI went from a 40 year old processor to a 14 year old processor…and now 8 years later they still sell that calculator for basically the same $100 price point they have been selling for decades. Could be a good topic for a video, I don’t know.
Boo TI. HP 4 lyfe. or, in RPN: Lyfe 4 HP
HP41CV or go home!!! 😁 Once you go RPN, you never go back!
Had a TI84+, loved it, but when an Android phone that costs less than the calculator, running an emulator, running the calculator OS, works better and is a better UI... you might want to reconsider your price point, TI 😅
I would suspect that certain college campuses REQUIRING students to own one for math class (and not allowing anything else) might have something to do with the artificial pricing and outdated hardware.
Just the type of nerdy talk I love
I liked the part where they did the thing
Exactly bro
Man. You won't believe.
Thanks for a really nice video. I love your enthusiasm for the genius of the Leica camera and their special shutter servicing equipment. It is a great observation that it used separate forms of technology and visual phenomena to work. It is nice to know that there is a group of folks keeping film photography equipment alive. Thanks again!
Thank you. Your curiosity and joy keep my mind healthy.
the German Handbook looks very specific and mentions everything, even the diameter of the screwdriver you should use 😂
It's German, I would be shocked if it didn't include that kind of minutiae
Destin always answers the questions I didn't even know I had, but I'm always amazed at what I learn
Loved the video Destin! Happy to hear you visiting us in Finland! Would love to hear more of your trip and experiences you had in here! No doubt nature and sauna were included! 😊
Been a client of kamerastore since a couple of months now. For being a finnish store their prices are very much reasonable. Greetings from Italy!
The advancement of technology over the past century is freaking crazy. I love seeing where a lot of our current technology evolved from. Great video Destin!
We can't even imagine where we'll be in another century
Aliens. History Channel dude told me.
@@Noah_7s we will be back to swords and horses .
@@LolSho0orTs that’s best case scenario
I love the old analog tech as well.
I love seeing you dive into these deeply technical bits about how cameras work! I had never considered the non-linear speed a spring would move the shutter. This also is a great demonstration of why cameras can (traditionally) only sync with a flash up to a certain shutter speed. Once the shutter speed is high enough that the rear curtain starts closing before the front curtain is completely open, the flash does not stay illuminated long enough to cover the entire frame as it is exposed. That opens up so many other topics like how flash duration is measured, T.1 and T.5, how the capacitors discharge at different power levels will affect duration, how leaf shutters work, and how modern high speed sync works. Once you start trying to use flashes to compete with sunlight it starts getting tricky!
Would love to see an episode related to this episode and also involving flash photography. Basically explaining to me, some of the stuff you mentioned here and why/how correct flash speeds work!
These mechanical camera shutters are truly feats in miniaturised engineering. Some implementations of the 'cloth shutter' had a window that was pulled across the shutter opening by ribbons across the top and bottom, a tiny brake to slow it down a bit as the shutter reaches its home across the opening. Later more updated designs had titanium shutter blades - between 4 to 6 of them travelling vertically in order to use faster shutter speeds with high speed flash guns. Older flash guns could operate at 1/60th of a sec., and more modern flash guns would operate at 1/250th of a sec., and the need for the shutter to travel a shorter distance, much quicker as well, hence the vertical 'guillotine' shutter. Fascinating engineering and fully mechanical too 🙂
The manual is nice to read. Such easy to understand diagrams, such clean sketches of the camera it self, and a well written text. How nice would it be if we actually got good manual again and things would be repairable.
Love this Destin! One of the reasons I love playing around with older technology is because its a testament to the ingenuity of old inventors and engineers who lacked much of what we currently have
Whilst I love the deep dive stuff, it’s these type of video, where something unexpected gets Destins child-like curiosity going, that are defiantly the jewels in the collection. You can feel the excitement as he understands what is happening, and then hear the cogs spinning as he works out how to explain it to the rest of us. Brilliant! Thanks Destin - Please keep them coming :)
I love how you figure out how something works, that I didn't even know I wanted to know. Much respect.
This is a great video for me, my great grandfather held several patents with Kodak. When my grandmother was alive, I got free tours of the Eastman house and other facilities in Rochester. I have several Leica cameras/lenses as well as slides taken in the 30's and I am piecing together our family history with these.
As a photographer of some 30 years, as soon as you said the phrase "persistance of vision", I was excited to see what was within. So much fun. Thank you.
Same. Not a fan of the term bokeh like I am of more proper Circles Of Confusion... wonder if he ever looks into the math and calculates some for us in a vid some day.
Mechanical solutions are like poetry as they are complicated and elegant at the same time. There is something really honorable about keeping those marvels alive in a time of cheap throw-away tech.
First time I seen anyone showing the "Rolling Shutter " function. Loved it. Kitos to Suomi and Smarter Every Day!!
Literally after the first words coming out of his mouth: "Ah I see, a fellow Finn."
Torille!
That Finnish accent. Love it
This is such an incredibly challenging concept to visualize in a video but I came away feeling like I really understood this after it!!! Amazing job.
Everytime, I love the way you introduce stuff with such enthusiasm!
I knew about this machine and how Leica cameras were adjusted "back then" - but I did not know how it works. I think this is even better than the usual electronic measurement, as you can also see if the shutter works inconsistently (like having one shutter curtain catching up or traveling with varying speed). Absolutely cool!
It's amazing!
I tell you what, absolutely love this channel. Been a subscriber for some time now, and I love watching things that have nothing to do with me, but it’s so fascinating to me, and I go and tell my friends who don’t care at all. I even got my older brother who’s 24 hooked on you. He loves it! Thanks Destin!
The love and passion you put into every subject you present is infectious Destin.
Brilliant! Recycling is key to resource management AND preserving our history!
Thank you for coming to Finland! The people at that store are a great example of what you'll find all over the country - humble, kind, generous people. So glad to hear you had a great experience here. 🇫🇮
out of all the photographers i follow on social media, Destin is the only one that itches the engineering aspect of photography that i can’t get over and i LOVE it, keep up the wonderful work !!
i am so warmed to see camera rescue on this paltform they are probably my favorite camera project in the world!
This is such a cool example of rolling shutter! It's impressive how fun you can make such an informational video. Keep it going!
Hey Destin, in a convergence of interests between video series you've done, this video put me in mind of Theodore Roscoe's book Pig Boats (about submarine warfare in World War II). In the section, "Submarine Photographic Reconnaissance (Nautilus with a Candid Camera)," - on page 272 of my 8th printing copy from September 1982 - it is described how the cameras issued to the US Navy for periscope reconnaissance weren't up to the task. However, the lieutenant commander of the Nautilus had a German manufactured Primarflex camera, which proved so effective that the model became standard issue for future periscope reconnaissance during the war.
As long as there are people like Destin showing us on KZhead this amazing things I know this social is not doomed like all the others right now
I just watched this video with my kids and I saw immediately what was happening. I use a strobe tuner to tune my musical instruments. It's based on the same visual mechanics, combined with audio waves. It's the most accurate way to tune. I love it. Thanks for doing what you do!
Outstanding ingenuity. Thanks for the video!
I regularly use stroboscopic imaging in my research, so this video was especially fun to watch. Thanks for another great video Destin!
Not even into cameras but one of the coolest videos and best explanations you’ve made in awhile! Love your stuff Destin! Can’t wait to see the baseball cannon again!
So cool to see Kamerastore in real. Did some orders online,never knew how they work and what team could be in there🙏 Nice video👍👍
Insane love for those artifacts, nostalgia never dies
It never fails. Something I think will be boring, Destin make interesting and exciting. Thanks for the great content!
Dustin's charisma and upbeat attitude makes me get excited over things I never thought i would get excited about ❤
Every time I learn about midcentury analog engineering, I’m amazed at the puzzle pieces they put together to achieve the things they did.
Yes, how they designed the internal of early semi-auto rifles has always been fascinating to me.
Guys are truly blessed with what they do. It doesn’t get much better than loving your job. If you need to work this is.
As a fan of your videos Destin as well as a KameraStore customer and a Finn this was a very wholesome video about the things that can be done even with vintage technology. 😊
I love this channel. From your enthusiasm about every single subject you tackle, to the level of dedication to the science, to the clear intention of making everything completely understandable to everyone, no matter the level of schooling. Even the little psalm you add to the end of every episode, always pertaining to the subject. It all speaks volumes about your love for what you do. You are inspiring.
AMEN!
I call it the Destin Effect!
Destin, you have featured two of my all time favourite cameras. A Leica and Hasselblad, I couldn't afford either. I had a full Bronica SQA system which cost me £12,000 new. Had I bought it in Hasselblad it would have been three times that. I also used a Mamiya 6x7 with the bellows body, it was great but my 5"x4" land camera could do everything I needed. My ex sold my Bronica SQA system, I wasn't happy. When I discovered what she got for it I was fuming, she got £600 for the three years old system including my Elinchrom flash lights. She didn't find the boxes with my darkroom in them.
My favorite camera is the A-1 also! I have had it for 3 ish decades. I bought a lot of lenses for it when their prices dropped as auto focus SLR started to take off. I remember my dad teaching me how to use a full manual Olympus 35mm range finder, back when I was in elementary school in the early 80. Now I know a place I can sell some or most of my camera collection to since they repair and resell them and they can have a new life. I really enjoy your excitement and content. Keep up the good work!
I love that with every video you make I become fundamentally closer to the things I have in my everyday life. Thank you.
My dad had a Leica camera, and I played around with it (and dropped it once), not knowing what an incredible piece of engineering I held in my hands and played with! I remember seeing that rolling shutter in action. It's unfortunate that his Leica equipment is not in our family, but I'm hopeful that they went to people who properly appreciate them! That's more important than me having a "trophy" in the back of the closet.
Thank you, informative, effort appreciated!
Kiitos - another great video & that you are showing a business because of what they do & who they are, not how much they pay, makes this channel refreshingly true & wholesome & one of the best knowledge feeding tubes on this platform. Kippis!
This is why I'm a patron. This stuff is awesome! Keep bringing us fun concepts that we never knew we were interested in, Destin!
Génial !!! J'ai adoré cette vidéo et pouvoir voir le fonctionnement de l'obturateur. Je suis toujours impressionné par l'ingéniosité des anciens !
The sounds and clicks and shuts and ticks and noises in this video... cured my depression.
I knew the KameraStore before and wanted to offer them a few older lenses for sale some time ago, but never got around to it. But nice to see the store directly. They really seem to be having fun with it!
Really cool video! Thanks for going into such detail and also keeping it simple to understand!
I love electro-mechanical stuff so much. This makes me happy that this exists
I had a little chuckle. When I loaded KZhead, and the video started its preview, the subtitle read, "(speaking in Finnish accent)" instead of transcribing the actual spoken words 😂 this was a really cool video, and to think the measurement technology is close to 100 years old is absolutely fascinating.
After years I finally understood how it works...thanks for having shown both techniques, ancient and modern.
met your channel today at veritasium video from 7yrs ago (the syncing vid) and i've seen you alot in his vids but never knew you had channel. your channel, your projects and you are precious. this video was also amazing. please never stop. big big love from iran. GL Destin ^_^
This channel was one of the big reasons I got into film photography as a mechanical engineer, and I absolutely fell in love with it. Please keep the camera content coming, there are so many incredible engineering problems that were solved with simple mechanical systems to be explored.
From the insane giddiness in every video when Destin learns something new to the bible verse at the end of the video... there is always just something special about SED videos and im entirely grateful for your channel Destin. Thank you Destin and to all the Patreons! One day, I too hope to support you in what you do; teaching everyone that there is ALWAYS a way to enjoy something you never even knew about!
Thanks, Destin! I have an old Konica, mostly mechanical, camera. The only thing the coin-cell batteries do is power the light meter. I never really thought about measuring milliseconds mechanically. It's both mind-boggling and amazing that people were able to figure it out out and make it work reliably when mass-produced.
Another brilliant film. Thank you.👍👍
Drawing lines on ketchup bottles to explain something? Ah, the age-old tradition of turning condiments into a visual aids
The Brits and Germans didn't experience as much success due to the wildly varying shape of mustard jars.
OH MY GOD, this is the crossover I never saw coming and never knew I needed! I love these guys! Now I need all sorts of content with them about repairing old cameras
Totally! I love Smarter Every Day and I love Camera Rescue! I have wanted to go to CameraRescue these last five years that I have been in Berlin (from Los Angeles)! I discovered them just after we moved here and wanted to work with their German rep. They did a Berlin event but I wasn't here at the time! I would love to do some kind of monthly clinic where people could bring in their old cameras and we could help them use them, get them repaired so they could use them, or sell them to someone who could use them.
Wow, that's incredible. Thank you so much for this content 💯
It's easy to understand how this works once someone explains it to you. Coming up with it for the first time and putting it into practice is a whole other thing. This took some serious mental power.
You should talk about the constant speed of the curtains. Horizontal curtains such as these cameras have a flash sync of 1/60 and vertical shutters have a flash sync of 1/125 or 1/250. Love the video!
I agree. It might be worth noting that this method can be used to determine both the curtain speed and the curtain separation.
The stroboscope principle is also used for tuning musical instruments -- turning something you can hear into a clearly visible pattern so you can make fine adjustments. You could do a follow-up video about that. There was the Conn Strobotuner, later bought by Peterson.
Its also used to set ignition timing on older cars and engines
