Definitely the best description of diffraction I have seen.
That's what we like to hear, thank you.
those laser demos are insane
Props to the editor
Hi Karl, great video! High quality, fun in the way you bring the subject, animated. Thanks for the wonderful explanation on diffraction!
My pleasure!
Hey Karl, perfect explanation. Before I became photographer, I studied engineering, my hobbies are physics and mathematics and I 100% enjoyed this video.
Ah that's good to hear from someone who has your background!
@@VisualEducationStudio Same for me, I am a grad student in a Ultrafast laser lab as well as a photographer and few have put it better. I even got into a whole debate with my Fourier optics professor about the lens sweet spot because he argued that wider aperture is always better, which is true based on the diffraction limit for ideal imaging systems, but not when you consider aberrations. I feel that my technical background has served me well in my photography and really is crucial for getting the absolute most out of my equipment. I cannot emphasis how articulate this video was for people of all backgrounds, providing great value without getting lost in the weeds.
I hope to publish a video like this one but on the subject of the 500 rule and NPF rule for astrophotography, and this will be the standard I aim for. Cheers!
Thank you Kevin again great to hear coming from your background too.
This is a masterpiece. It will age like good wine. And it will be forever relevant content.
Thank you so much!
First video I've watched and I'm subscribing. The amount of work that went into this video.
Diffraction is one of the bigger scapegoats for photographers, in a strong field. For 99% of you, your uninspired metaphorical eye is what is ruining your images. Focus is probably second, and a distant one at that. I'll agree that provided everything else is already optimised, it does start to matter. In any case, this is a fantastic description of how diffraction occurs.
Great production. One side note: sensor resolution / pixel size doesn't contribute to diffraction, but it can contribute to making it visible. A higher resolution just means you are making those smaller visual artifacts, which were already there, visible.
In other words, increasing the resolution of the sensor above its diffraction limited aperture doesn't REDUCE sharpness over the lower resolution sensor - but it also doesn't increase the resolving power, because the image is diffraction limited.
When the image is NOT diffraction limited, i.e. when using a large enough aperture, using a higher resolution sensor DOES increase its sharpness or resolving power.
superb video, very easy to follow the explanation, subscribed!
Wow you went to great lengths to explain this with all those demonstrations. Much applause
Thank you.
This is as informative as it is entertaining! 🚀😄. Great work.
the production quality of this video beggars belief , unbelievable amount examples and effort gone into breaking down the concept. BRAVO!!!!!!!!!!!
Glad you enjoyed it!
I already knew the effects of diffraction well, but I watched the video with interest, curiosity and amusement. Compliments!
Amazing, detailed and entertaining production. Thank you!
Damn this is good. The amount of scene changes is something only other creators will recognize but my goodness.
Nice David Icke cameo at the end!
Yes. All other things being equal, the bigger the aperture, the smaller the airy disk, and the higher the resolving power. Of course, depth of field is a limiting factor, but for infinity shots, wide open is theoretically your sharpest aperture. Unfortunately, few photographic lenses are actually diffraction limited, but some expensive ones are close to it.
Excellent. For a future presentation, please discuss diffraction with a B&W monochrome sensor vs an RBG sensor.
What difference would that make?
Nicely explained. Well done.
unreal explanation
The presentation style was really good, but the demonstrations you added helped a bunch and tied everything together in a great way!
Using a wire to demonstrate diffraction is something I haven't seen but the results speak for themselves!
Thanks.
You hurt my brain. And added to it at the same time. Nice.
Such an effort for a video with relatively few viewers..
You are a true Artist!!
Thank you very much!
very informative and entertaining, good job guys!
Much appreciated.
Great overview. There is another technique, of course, and that’s tilt/shift/swing, to actually move the focal plane to intersect with the areas of critical focus. For full frame systems, however, there are just not that many lens options, and what options there are have limited movements, and rarely have autofocus, so may not be good for action. One can invest in technical systems like Cambo and gain plenty of movement options, but that is expensive and bulky so best used in static work.
Excellent video - appreciate the extra effort applied to accentuate key info.
Very welcome!
So much work for a single video! Wow, deserves a like for sure
Thanks!
After watching a lot of videos this year I have to say this one is on another level. Great job both explaining the topic and making the video!
Great to hear!
the amount of hard work put into this video is unparalleled, plus te information is priceless and relevant. Thank you to the team that made this happen.
Welcome.

"Oh, is that Karl Taylor? Explaining diffraction? He's gonna do a pretty good job, I haven't watched anything from him in a couple of years but he always went in depth and with great knowledge. Surely his style and presentation haven't changed a little-"
New level of visual education!
Optics and quatum mechanics !! I felt like i was on a Physics class for awhile ! Amazing content Karl !
Glad you enjoyed it!
This video is really great at all levels, thank you for the amazing work!
Glad you enjoyed it!
Great video, I'm thankful that outdoor photography in uncontrolled environments is my thing!
Impressive video in so many ways !
I've tried pin hole / camera obscura on my FF Sony, and the results are, well, artistic if I'm being generous.
Never occurred to me that diffraction is mega, when having an aperture value of 120.
Love the fun vibe of this video!
As an engineer married to a physicist who spends much of his free time pursuing photography I very much appreciated this video. I always felt like I had a good understanding of it, but I never really considered the airy disk relative to size of the photosites so that was a really great point you brought up. Intuitively over time I have learned how much distance from a subject can affect DOF and I'm glad you mentioned that as a solution as I feel it's one of the more overlooked topics that take new photographers a long time to wrap their heads around. Wonderful job on this, just brilliant.
Thank you kindly.
This was brilliant. Reminded me of the quality educational stuff you used to get on Channel 4 in daytime TV years ago.
Much appreciated
Wonderful video explaining diffraction. I was familar with the issue at a high level, but the demonstrations were super helpful to solidify my understanding. Plus - super engaging video!
Excellent thank you.
I thought u would be lecturing about photography and lenses but it was about wave-cancellation pattern education! Very good video about the experiment! Thanks! I got it all ! Super thanks! Love it!
Thank you!
As you decrease the size of the hole, things become more difficult, you killed me with that one
The video’s content is truly enlightening. It presents complex ideas in a way that is readily understandable, making it a valuable resource for anyone interested in the topic, which still has many question marks.
Thank you
6:55 When *focus stacking* especially macro, you can see that changing the lens-to-sensor spacing is also *changing the focal length of the lens* and thus also the magnification of each layer. An "IF" or Internal Focusing lens has less of this phenomenon, the whole lens does not simply move forward but lens element spacing is adjusted. A 60 millimeter Micro Nikkor is an example of such a lens.
It can sometimes work better to adjust the camera to subject distance to avoid changes in focal length, but that also changes the apparent size of the object. When I do wildlife that's how I do it; move forward or backward slightly while shooting frames so that the lens is not changing focal length. For super precise work, a combination of the two to keep the apparent size of the subject the same for seamless focus stacking.
All those real life examples were really good and helpful. Thank you very much for the effort. Keep it on.
interesting recommendation, thank you YT
That was a great video 👍. Very important and critical information presented in a funny way 😂
Thanks! 👍
I....I actually love this new format...Keep it up!
Glad to hear it!
keep us tuned karl taylor
At reasonable f-stop, diffraction limits are usually way smaller than the pixel pitch.
The takaway of this video is: don't use unreasonably small aperature when taking photos.
Karl! this is GREAT. I've been dealing with defraction the past few months when filming trying to figure it out. What a wonderful coincidence you've made this video! Loved your channel before but am loving the remodel too. I'm wondering if you will cover aspects of cinematography as well such as FPS, refresh rates for playback, color correction, different qualities of light i.e. soft vs hard, LED vs. Incandescent, CRI values, HDR, and so on. Thanks!
Now here’s a photography lesson I haven’t seen before 🎉. Thanks!
You’re welcome 😊
Great Video Karl and Tim was awesome! Great acting Tim!
Ah yes Tim might have another career path ahead of him :)
Amazing video. A lot of effort put in. Thank you!
Thank you for watching!
Nicely done. You answered a number of questions I had. Thank you.
Glad it was helpful
Thanks for building this. Incredible video. Fantastic explanation.
My pleasure!
Yay photography learning in a fresh new way! I will have to check out the courses sometime soon!
Well done! In a while didn't see such nicely made videos like this one 👍
Thank you.
Definitely helped me to take a look at my lens
Nice explanation with your show & tell😁 A big thank you.
This is what you call an in depth explanation👌👍😁🎉
Glad you think so!
Excellent video. I understand what you are explaining. And I know that a lot of effort went into this video and you didn't charge me to watch it. Many thanks!
You're welcome!
Karl Taylor with the script writer!
Great video.
Whether is a singular component or a combination of chromatic aberration, heat wave distortion, I get bad fuzziness when using a 2x converter on a 400mm during the middle of the day. Can really only use it for certain distances like getting a picture of a players face during the game or maybe just getting their whole body in frame.
Anything farther than that it can get pretty fuzzy.
But once it gets later in the day towards evening it can still be really good optically. And don't have a problem indoors.
I guess it's the amount of UV light because if it's during the time of day when you need to squint, then the photos suffer. If you don't have to squint, they'll be okay.
You didn't go into Nyquist theorem and its effect on sampling rates near enough. Focal length, aperture, and individual pixel size for each specific wavelength all play a role in critical sampling rates to achieve max angular resolution.
That was so entertaining especially what happened to that poor guy at that end and I learnt something new, kudos!
Thank you and ahh yes poor Tim! :)
The physical set ups to show the effect in practice were really cool. Excellent work.
Glad you liked it!
Amazing video!! Thank you so much for sharing this video
Glad you enjoyed it!
Great video! Very well explained and produced
Wow, I've never had the diffraction explained to me like that. I know what it is, but that was cool, and the ending, chef's kiss.
Glad it was helpful! 😂
First time I've seen one of your videos, and I have to say, you just got a subscriber. bravo!
Awesome, thank you!
Excellent explanation on diffraction.
Glad you liked it!
Very well done, this is the best understanding of diffraction I've ever had. I was very impressed when you busted out all those lasers, excellent job!
Wow, thank you!
Thank you for keeping the asides to a minimum. Excellent visualizations, definitely improved my understanding.
Glad it was helpful
This is so awesome, perfectly made!
Thank you so much!
Another Great video Karl!
Thank you very much.
You are welcome!
Wonderful blend of optical science,photography with humour. Truly a masterpiece.
much appreciated thank you.
00:45 Increases the depth of field either side of the focus point? (You mean even in the VERTICAL direction of the subject?! How it could be?)
Excellent
how do the hasselblad lenses do with chromatic aberration? even with all the raw file info of the X2D is it still limited by CA when editing? the mannequin arms falling off at cue was gold
fantastic explanation. thank you.
Thank you much appreciated.
Love the new style
Brilliant work,engaging and informative,everything I like. 👍
Amazing, thank you!
As Brazilian guy, I love that the editor take the frame from a Brazilian Novel LoL
Amazing video thank you.
Our pleasure!
This was awesome. Thank you.
Glad you enjoyed it!
Hi Karl with the post processing technique of selectively adjusting the image, could you then potentially shoot at the max or near max aperture setting for the deepest DOF possible? That we would/do see a deeper DOF in the image than if we stop before diffraction typically sets in and any blurriness from diffraction as a result of increasing the aperture to max/near max would be “corrected” via software?
Hi Karl thanks for the video. What trigger did you use on X2D 100c ?
What an amazing video! Congrats 👏
Thank you so much!!
Well doesn't this just bring back the days when I would end up telling my son "Because the laws of physics are spoiled little brats who always get their way". lol.
I am amazed by the manner of teaching in this video. So demonstrative and also fun 😃😍
Glad you liked it!
Absolute brilliant
Wow, excellent explanation!
