Hi Guys, we're glad you're enjoying this educational and entertaining format on these occasional special videos (see also our funny one on 'Diffraction')- If you enjoyed the video then it really helps us if you can share this video with your fellow photographers, thank you!
Just absolutely loved it. Humor can make the learning process so much easier and enjoyable. And...a BIG! shout-out to your lovely model whose antics brought your points to life! Kudos to you all!
This was hysterical. I have tears from laughing. At first, I wondered how you got the model to comply with your antics, then I figured you gave her the opportunity for revenge at the end. :-)
Another masterpiece! Some people learn to teach, some are natural but then there is another group that that are not just natural at teaching but are additionally passionate both in gathering knowledge not just by being taught too but also via experimentation and years of honing that skill, that’s where Karl Taylor belongs, almost in a class by yourself. I salute the master for teaching and educating us and making sense of our hobby, passion and for some a life long vocation. Weldone sir.
First comment I've ever left on UA-cam, but I had to do it after this video. Great to see you taking a lighter approach on this one, Karl. Incredibly humorous yet highly useful information. Though, I wanted to leave the post mostly to say that it was the model stole the show! What a sport. Bang up job, gang.
Karl, I decided to watch this video even though I already know the material. I'm glad I did. What a marvelous piece of video you and your team created in a fun, witty, deadpan manner, with such creativity and marvelous shot-making! It's also nice to see video makers focusing on eyes instead of the freaking ears, and it was nice to see you having fun with it!
I'm glad you addressed the shutter speed versus flash duration point in this video. Many people celebrating the advent of global shutter completely ignore this and claim flash sync up to the very highest shutter speed. Another high-quality video. I'm also happy the model got her revenge. She was a good sport about the whole thing.
Historically - I always thought that he was Masterfully brilliant in his knowledge, and was a bit overly arrogant. But, I would always love his technical input. However, I never ever thought that I would enjoy these learning tutorials the way that I am. He has even gone as far as letting a model push his face into jello. I think you are on to something excellent, and I hope you continue on with these fantastic videos. You have taken what could be tedious and mundane technical topics and made them into a very entertaining way of learning. Cheers, and Well Done, Sir
He's actually a very nice person. His teaching style came off as arrogant in early videos, but I think that just has to do with how he talks, not so much as intentionally being mean.
😂😂😂😂 absolutely fantastic. Funny video. And I know your model enjoyed slamming your face into that plate of jelly at the end hahaha. 😂😂 Very well done and very well put together 👏🏻 👏🏻
Great refresher! I had to rewind several times as I missed what you were saying once I experienced the satisfying "splat" of the model land on the floor! Great model BTW.
I am glad the internet has new and refresher courses on fashion and other photography if looking for work or as a hobby in retirement. This may lead to jobs if needed.
Top notch production and scripting. Reminds me of the UK produced tech/science shows. Entertaining and effective. You're on a great path with this format. Cheers
Brillant 😂. Well done Karl and team, explaining and showing a very important topic that is probably rather boring for most people (not me since I’m genuinely interested in technology) in such a great way, that is both easy to understand and very funny 👏👍
Thank you for all the fabulous educational videos over so many years!!! If I may make a minor comment. The very last point of your video indicating that only 1/20 of the light from the flash burst would be captured is somewhat incorrect. The issue gets complicated very fast but …. flash burst from strobes are not like constant light. It’s not a continuous output of light at a constant intensity for a fixed duration of time. It’s an asymmetrical burst of light with a fall off - it’s not even an even distribution curve. And there lies the problem with global shutter and current strobes. At very high global shutter speeds it becomes difficult to adjust exposure of the subject in a *predictable* way by varying the flash power setting - in the way we can do with standard shutters… I know that you know this - but just a clarification for viewers thinking that all is perfect with these new cameras using current strobes….

Hahaha, amazing! Love the bolder and wiser version of Karl 🤣
great high quality tutorial -though I am full of cold in blooming July and have spinal pain so not thinking clearly - I can't get my head round the last bit - if the flash lasts for 1/1000th second and the shutter is only open for 1/20000th second isn't that 20 x longer duration of the flash to the shutter aperture - not that it matters as I don't have that type of camera lol.
Our example showed that 1/20000th shutter speed would only capture one twentieth of an average speed flash burst of 1/1000th of a second, so a lot of the flash power would be lost at such high shutter speeds.
I refer to ISO just as Karl does.. “eye-ess-oh”.. and usually don’t care about proper pronunciation, but lately I’ve been seeing nonsense posts going off on people… suggesting “E-zoh” or “I-zoh”. I find the differences are rather amusing.
Oh Karl. Love ya man, and I can appreciate the silliness, but you are so good without it - that in my opinion, it is like comedy from Sam Donaldson or Ted Koppel (More green jello anyone?). Kidding aside, one real question here for you. My understanding was that increasing ISO in nearly all cases, just amplified the S/N after exposure had taken place with photons coming through the aperture and while the sensor is turned on (i.e. shutter speed in cameras with shutters). Are you really saying that increasing ISO makes the sensor more sensitive to light/photons - and there for part of exposure - which you said was a seesaw in your aperture video - or just that it amplifies what the sensor captured as exposure making it appear as if the sensor was more sensitive to light? THanks again.
@@VisualEducationStudio Thanks for the clarification - but I thought you said "making the sensor more sensitive to light" and I was surprised to hear you say that. I might have to check that out again.
I like your video, explaining flash synch and global shutter. I love the end of the video. Unfortunately, your explanation at the end of the video is not correct. I have shot more than 1000 pictures with the A9III and Sony HVL-F60RM2 @ 1/256 power, ISO 250, F/1.8 and 1/80000 and more than 30Pict/s.
Thank you but you have to consider the physics. What is the flash duration of your flash burst to reach maximum power and hold that power, flashes have a timing reference called t0.1 or t0.5 which are measurments of the main proportion of the flash rather than the tail of 'weaker' period of the flash. Anyway that being said, my example gave an example of a flash burst that lasted 1/1000th of a second which is common on a high power studio flash, speedlites can often reach 1/20,000th of a second burst when on low power. Either way though if the shutter speed is faster than the flash burst then the simple physics of that dictates that some of the flash burst won't be recorded.
@@VisualEducationStudio With a GS, it doesn't matter, if only a slice of the total flash burst is recorded with a shutter speed that is faster than the t0.1. About a month ago, I did some experiments, using 2x Sony HVL-F60RM2 on the low end of available power and 2 heads on a Broncolor Satos 3200 at the high end. The goal was to photograph some gymnasts with a very high frame rates and very high shutter speed using the A9III. The HVL-F60RM2 was triggered via wireless and the Broncolor via cable, as their wireless trigger didn't work. I could get perfect exposure with the HVL-F60RM2 all the way down to 1/256 at ISO 250 and F/1.8 with shutter speeds up to 1/80000. The HVL-F60RM2 is a 60 Joule flash . At 1/256 it puts out approx. 0.23 J which was sufficient to expose the gymnast at 3m flash distance with a frame rate of 30 Pic/s. Using higher levels of flash power does reduce the frame rate of course, but it is still around 15 frames/s. Of course, with the Broncolor, I had no problems to shoot more than 60 frames/s. Now what does that tell you. It is now possible to shoot at very high frame rates and shutter speeds at fraction of the cost using cameras with GS than without GS. The same is also true, if you try to overpower the sun in many outdoor shootings.
Well it doesn't matter that it will sync of course but the video explains that you will be losing some of the flash duration due to an excessive shutter speed but if you have enough flash power to cope with that then no problem.
Hi Masha, what's happening to the model isn't real, where she is falling on the floor it's special effects. On the jelly shots it was a lot of fun and we all took a turn getting splatted. This video is a parody of how bad some photographers are and it includes humour at the end where the model gets her own back by squishing the photographers face into jelly. The whole thing is worked out and planned with the model in advance to make sure everyone is happy with it. We always treat the people we work with with the greatest respect and our work is always a collaboration when working with models male or female. We believe, from the previous comments, that most people understood that this video was a parody of a bad photographer and how not to behave.

Wonderful as usual Karl. Thank you so much!
Karl, the young lady, looks very much like you. Is she your daughter?😊
Ha ha no, my own daughter is a little younger :)
😂😂😂😂 absolutely fantastic. Funny video. And I know your model enjoyed slamming your face into that plate of jelly at the end hahaha. 😂😂
Very well done and very well put together 👏🏻 👏🏻
😁
Great refresher! I had to rewind several times as I missed what you were saying once I experienced the satisfying "splat" of the model land on the floor! Great model BTW.
The production value of this is amazing! Way to VE crew! I giggled plenty
Always the best explanations, thanks Karl
KT, you have really leveled up on this one. This is the best explanation of flash sync speed available anywhere. Thanks for all the great content.
Thanks!
Thank you for that great information and for the great time, I really enjoy this one, and thanks to your beautiful model too.
Our pleasure!
The production of this is amazing! I wisk i could like this 1000 times over!
Thank you.
You did a great video and funny. I am retired, but like keep up with changes and tips just in case. Great work!! 5 stars
Super super high quality. This is the fisrt time in my life as a beginner photography to really understand what is flash sync speed. Thanks.🙏
Glad it was helpful!

I hope you paid the model really well
Yes we always pay our models well and Caterina and the rest of the team had a lot of fun on this one.
