About this video :
The term "stop" comes up a lot in photography and can be confusing, so in this video we explain what exactly is a stop, and how can we use the cameras aperture, shutter and ISO to control it.

I'm not the first, I'm not the last but when Paul uploads, I CLICK FAST!

Wow. I've watched your videos about ISO, aperture, shutter speed, light meter etc and pretty much got the gist from the videos but for some reason this video made all of those click for me. Thanks a bunch! It all makes a lot more sense to me now.

Hey Paul, Thanks for the vid! You do a great job. Just a heads up... ISO isn't based on light, although the scale (stops) is the same. It's just signal amplification:) The signal is created from photons hitting / propagating through the sensor. This produces free electrons thus signal. When you amplify the signal by increasing ISO you also amplify the noise that's contained within the signal. Thought you might want to know. Sorry to bother you if not!

Quite simply the most effective photography tutor on YouTube, your explanations are easy to understand for us beginners and I have learnt more from your channel in the last 6 months than any other. Photography is the art of capturing light and you explain it so well. Keep up the great advice Paul its invaluable when starting out on such a great hobby 👍 before much longer, with your continued help, I will stop regarding myself as a beginner but I know there is a long way to go and much more to learn

Paul .... I was an avid photo nut ... purchasing my first Canon QLFT 35mm camera while serving in the Navy during Vietnam. I've used that camera, (with almost no manual modes) and was pretty proficient, in film speeds, f stops, and shutter speeds. But life kind of got in the way over the last 20 years, and I rarely picked it up, in part, because digital cameras took off ... I bought more than my share of point and shoot digital cameras ... enjoyed the concept of digital, but delayed buying a DSLR equivalent for my Canon, as they were too pricey (and the multiple lenses I bought for the 35mm wouldn't be capable of carrying over to the digital.) Then I retired ... time on my hands, and point and shoot cameras had to fill the bill .... until one day, two years ago, I walked into a pawn shop nearby that was advertising, that it was going out of business ... and found a slightly used Canon EOS Rebel T1i with two lenses and battery charger for $121.00 US. So I now own a decent digital DSLR camera, and forgot everything I knew and used about film speeds, f stops and shutter speeds. That and at 70 years old, lessened eye sight ... but I have been a subscriber for several months and am finding a lot of great information ... helping me on my way to use some of my spare time, back in photography. I want to here say ... Thank You.

[ChillinDylanX]

Excellent explanation! It’s funny I’ve been photographing for years but the concept of stops always mystified me. Thanks for demystifying stops!!! 👍🏻

[markadams]

You're a great teacher sir, thank you.

Thanks for the clear explanation! Love your videos.

Paul makes everything very simple and easy to understand. For sure i'm taking better photos and understand what things mean by watching these videos. I get it now sequence of numbers that corresponds to the sequence of the powers of the square root of 2, doubling light f/1, f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22, f/32. F stops like 7.1 are 3rds of the F stop 5.6. Thanks for explaining

[Steve_Wardley_GJEF]

Thanks Paul, another corker of a tutorial.

[a.beckwith]

Thanks Paul, that was the best explanation on the subject. Cheers

Your videos are the best. I've been trying to learn photography concepts via YouTube videos for a couple of years now, and have watched many. Yours always have just the right amount of info to absorb, and are presented in an easy-to-understand way. I also love that you often use a T7 and demonstrate that you don't have to have a $3000 camera to take great photos. If I ever made it to Australia, I'd love to take one of your classes. Thank you.

[davewhetton]

Thanks for this. The way you explain exposure, together with great visuals, is fantastic.
