TYVM you’ve solved all my prombels
Thanks for the video. by scaling up. you also lose precision in the values of RGB due to the sensor getting values in 12 bits precision. Better sensors of 14 bits help to reduce this effect.
okay so now all we need is the aperture and shutter speed tutorial and life is good. or maybe make it a combined exposure tutorial with all 3. that would be cool.
Why do sensors with more MP have more noise? My Nikon D700 are knows for low noise because one of the reasons it “only” has 12MP.
because the sensor size is the same. The pixels are smaller
great explanation … it really did clear up how boosting ISO works. thanks for posting … hope you do more in this series!
Ahhhhhhhhhhh 😀 thank you sir
I had a basic understanding of how noise was introduced to the sensor while amplifying the ISO BUT…. Now I am the GRAND MASTER of all things ISO. Thanks Dylan, please do some more of these tutorials if you have time, they have helped me tremendously!
You are the BOSS, thanks a lot wanted to know this for a long time
What causes the grain in film since there are no interfering wires?
Please do a video explaining histograms.
Yes, it did help.
But I can’t quite contemplate how darkness has more noise. If there’s a small amount of light, surely the noise is going to be as small?
Actually, maybe it’s because the contrast brings out noise and because it’s always going to be in dark areas, it just blows it up even more?
Well, anyway, this really helped! Thanks a lot!

Useful.Thank you.
does this mean if every electronic wire/cable that runs close to the camera is shielded, and the sensor is somehow shielded to an extent from electromagnetic influence such that the sensors do not pick up extra colour/noise that is not coming in from the actual photo subject, then we could create a camera that can theoretically have an unlimited ISO number with no noise at all?
Well, “theoretically” is the key word there. In reality you’ll never achieve a perfectly noise-free environment. The sensor itself is even adding to the noise. However, as mentioned, as they get better and better technology, this becomes less and less of an issue. For a specific example, search for “EOS 5D Mark III ISO 12800 MOVIE” on YouTube to see the noise difference between the Canon 5D Mark II and the Mark III at the same ISO. It’s an impressive improvement.
you are wonderful.
I fumble trying to explain things to people when they ask me. I am so glad I found you because now I can proudly point them in your direction. You are like the Khan Academy only for photography….Love it!
*Big hugs to you*
Thanks for sharing your knowledge.
Very clear! Now I understand the reasons why higher ISOs generates more noise.
Thank you!
this is interesting..
1. If ISO means scale-up the RGB, that means if we increase the ISO then our images will become much brighter.. !
2. The noise is from that kind of interference ? then, how can larger sensors (e.g. the one in DLSR) can reduce the noise ? If the noise is solely because of this kind of interference, I guess larger sensor camera won’t help in reducing the noise.
1. Yes, true, but at the expense of more noise. 2. Larger sensors tend to have larger individual pixels, meaning a pixel physically receives more light than it would with a smaller sensor. If the sensor is built well, then because the pixel is getting more light, the amount of light compared to background noise is much better and you won’t get as much noise when you scale up.
I see I see, so ..
1. in my PnS camera if I increase the ISO, the shutter speed becomes faster, in order to compensate the bright images.
I love you
Very helpful, thanks! I just bought the Sony A65 and im so green!! Willing to learn
Gotta love the sensors these days.
There was a time where ISO 800 was ..touching it.But now you can push your camera into the over 12800 and ..still get some decent results.
Do you know how long exposure noise works on digital sensors? It is one of those situations where you gotta choose between two bads.Either accept long exposure noise or raise the ISO to get noise from there.
When first handling A DSLR begin in the green mode. The full auto, once you feel that you get the camera better. The buttons and the feel you can switch to P[rogram] mode or modes like A[perture] these give you more control. And yes will do most functions like measuring the light automatically for you.
Slowly learn to take more control.
I own a Dslr for 4 years now and .. Aperture is my most used mode. I like the effects. So take it slow.. and slowly learn to take more control.
your videos are well explained bro, good job!!!

Thank you so much for explaining it in layman.. trust me at the end of this video I was able to LEARN… thank you
Thanks for this video!! Excellent explanation of ISO & noise.
Which software do you use?
This and the DOF and F-Stop videos are among the most informative, professionally produced and clearly explained videos I’ve ever seen (and not just on YT)
Thanks so much Dylan – really appreciate your time and look forward to more of these if you make them!
Simply awesome :)
Very good explaination ..thank you 🙂 I have a small query here, when you mean new cameras are not affected by the noise, does it mean the SLR?? or more specific I have a canon 1000D ,so is it good to have high ISO in low light condition. Previously I did this and ruined all the pics I took at a concert in low light.Look fwd to your answer..
thx. super video!
very interesting, I was looking for explanation but no one knew it even the photographer had an idea about it, they just know high ISO equal to high noise. and low ISO equal to low noise.
Thank you so much for your effort.
so using high iso with many light(outdoor) only get shutter faster etc, not loosing much quality?
thanks, really helpful video!
good job on explaining it..i now understand very well bout ISO
i love taking pics and i wanna enroll in a photography class…however theres a big problem…im color blind … =[[[ so being a photographer is just a dream….forever..
