Master the Exposure Triangle in 15 Minutes: Shutter Speed, ISO, & Aperture Explained

[@KovarrBlue]

I decided I'd start photography after a lifetime of wanting to get into it, but never committing. After having taken 3 online courses on it, I've learned more by watching this video than in all three of those courses combined. You made it easy to understand, you gave definations of terms without me having to pause the video to go look things up, and you used a nice, steady pace. Thank you for making this video - you have a new subscriber.

[@JohnGress]

Wow thank you so much and enjoy your journey!

[@Boohooooo]

I hope you’re ready to spend some money. Idk how serious you’re going to take it but you’ll never stop spending money depending on what level of photography you choose to strive for. Whenever you think you know photography, you realize you have no idea. It’s something you have to love like athletes love sports. Again all this is based on what level you choose to pursue. Best of luck to you. 🙏🏾😎

I was familiar with this around 2 decades back and forgot it since using point & click phone camera. I'm returning to dedicated cameras. I'm a visual learner and this was the best and most easy to digest explanation of the shutter speed, aperture and ISO ... thank you, this is much appreciated.

[@JohnGress]

Thank you so much. That is great to hear and good luck with your journey!

[@meeensch]

I've learned more watching this video than I did with days of research to better understand the topic. Awesome job, thank you!

[@JohnGress]

Wow! Thanks. Thats great to hear!

[@MrLuridan]

The water analogy was brilliant. Thanks for this video, very helpful

[@JohnGress]

Awesome! I hope it helps!

[@MrLuridan]

Also, this was the most helpful video on this subject I’ve seen.

[@JohnGress]

Thanks!!

[@redesign5096]

Thank you! This slider helped tremendously. Best video on triangle exposure!!

[@JohnGress]

Wow! Thats great to hear!

[@Twobarpsi]

Excellent explanation!

[@JohnGress]

Thanks! Glad it was helpful!

[@blakeronan]

so...... just as a good indicator ... I was about tp purchase a course on Exposure Triangle - and on this gentlemans video - at 03.33 - Ive learned something new .. immediately .. and John didnt need some hyped up intro trailer - (Im really starting to hate those things on every video) .. ok .. Im at 03.36 Ill proceeed to learn.. now.. click...

[@JohnGress]

Thanks. I hope it helps.

[@movingourmind]

Cheers buddy. Very well explained :)

[@JohnGress]

Thanks! Glad you liked it.

One nice thing about the growing popularity of film photography using used, typically antique cameras among younger folks, is that they’re getting to learn this by doing. You might point out that on a fully manual lens with a leaf shutter inside it, the shutter speed and aperture form a parallel row of numbers exactly like the chart your high school teacher had. You can turn both dials together, and any combination of the two you select will remain the same exposure. Makes the area of the aperture half the size, and only half the light can come in, so you need to expose for twice the time. Honestly, I would hope anyone who watches a channel as advanced as your would already know all of this. 😂

[@JohnGress]

Thanks Bob! I never used a medium format camera so I didn’t know that. What a genius design. By the looks of the low view count, I think making a video on something so basic was a bad idea. Oh well I still get a lot of question where the people just don’t get these basic fundamentals. 🤷🏻‍♂️

[@videoal]

Good video here and I learned a lot.

[@JohnGress]

Glad to hear it!

From a practical point of view and as a start spot on... however I tend to point out from the beginning that this is only 100% correct in analog photography and that in digital ISO doesn’t really exist, however for practical reasons of continuity the digital ISO settings are configured to mimic the analog equivalent; finally I point out the differences between film grain and digital noise. I only go deeper for those interested and when introducing noise reduction techniques. As much as I understand the need to simplify concepts for ease of comprehension, a pet peeve of mine is to never mislead, if I use a simplified concept I point it out, I say that there’s more to it, otherwise further down the line it might be difficult to understand what’s happening and/or making wrong decisions.

[@MattLeader]

terrific explanation!

[@JohnGress]

Thank you so much!

[@SovanoraHounKhin]

Very interesting about the triangle setting information. I would to see if you have charts of Triangle settings - sunny day - cloudy day - rainy day - evening golden sunshine/sun set - morning sun rise - birds flying - air plane in the sky - fishing jumping in the water - fast boat - fast cars - running - gymnastics - sports Thanks!🙏

[@JohnGress]

It's all about selecting a shutter speed adequate to stop the action, which you can determine through trial and error and then selecting an f-stop that will result in the depth of field that you desire. After you make those choices you will dial in the ISO and if that number is too high, then you will need to change one or both of the other two settings until you are comfortable with the outcome.

Awesomeness! Thank you!

You're very welcome!

Random question, but what city is shown at 5:31?

[@JohnGress]

Chicago.

[@mas502arc]

@@JohnGress Sorry, I meant the city in the very next frame, at 5:33.

[@JohnGress]

Rio!

[@mas502arc]

@@JohnGress Thank you! Great video btw!

[@GeeQueee]

Do u have one fr video?

[@JohnGress]

Set the shutter speed to double the frame rate and then adjust the other settings. If you have to, you can shoot at the frame rate or 4x the frame rate, but it’s not ideal.

When did the exposure triangle become a fad? I don’t read Ansel Adams write about the exposure triangle.

[@JohnGress]

For what its worth, I didn’t learn it as a triangle and I only heard people use that term after KZbin.

[@philshock3805]

While that's true, Ansel was still using it in practice. It's just a teaching tool to illustrate the relationship between the three variables.

[@pdcorlis]

As a memory tool, a triangle is a pretty good device. As a functional expression of how these elements relate to each other to create proper exposure - it doesn’t work. Go ahead - label each leg with specific values - ISOs, f-Stops and shutter speeds - then try to make it work. It really doesn’t.

[@GeeQueee]

Still lost

[@gregfaris6959]

I find it a bit comical to hear people talking about the "exposure triangle". This guy speaks of his "early photography instruction" in high school, while failing to mention that it was about 15 minutes ago. The reason this is important to mention is that in all traditional photography, the sensitivity of the light-sensitive material (film, plates, sensors) is definitely NOT a variable you have control over, in thye same way you control f-stop and shutter speed. The actual "speed" or sensitivity of the light-sensitive material was either printed on the box (in later years) or determined by the chemical concoction you may have come up with (in earlier years). What I find comical is not so much that the "educator" here has absolutely zero information of the history of his subject, nor the origin of the units used ("ISO") and where they came from, but that armed with the vastness of this ignorance of facts easily researched and elucidated he continues - confident from his pulpit of manure-pit ignorance - to wish to educate us on a subject of which he has not the slightest inkling of its origin - nor of its significance.

[@JohnGress]

Thanks for the huge compliment! I took that high school class I referenced in 1992.

[@mridangaplayer]

lost me when the numbers came out about the triangle

[@nelsono4315]

mastering the exposure triangle will help you take control of your camera. It won't necessarily make you a better photographer though. That's up to you.
