excellent 👌

This video Did more for me in 40 minutes than i have learned in 10 years of watching other videos

There was a method I used to do with my old point and shoot and old phone camera because they produced a lot noise and didn't have manual mode. I would keep my camera very still and shoot in burst, creating like 10+ images of the same scene. I would take those images and stack them into 1 Photoshop project. I might want to select all the layers and auto align them just to be safe. With all of them selected, I would then convert them into 1 smart object. I would go to the top of my screen and select Layer > Smart Objects > Stack Mode > Mean and this will blend all the images together. Because the noise location differs from one image to the next, blending them will smooth out the image as if there is no noise at all

This is by far the best de-noise tutorial out there. And I’m watching and searching for years. Thank you, this is treasure 👍

Scott you’re a national treasure mate…this was awesome

The Alt key and sliders blew my mind. This has been the best explanation of noise and sharpening I've ever seen. Thank you!

Now this is the kind of video I crave for when I want to learn something. Highly detailed, well explained, and no BS. Learned quite a lot from it. Thank you so much for such top notch video!

Can I say, "I love you, Man" without getting too personal? At 1minute in, I said "thank the lord". Reason: I'm an amateur photographer that hasn't been shooting more than a few years. After the first year, I did a ton of reading (and still do). I could tell people more about OSPDAF systems then they care to hear. I've heard far too many professional photographers (with KZfaq Channels) who will frequently state that ISO is part of the exposure triangle - and as you say - that turning up ISO increases your camera's /sensor's sensitivity to light - which it absolutely does not. Now before I sound like I don't understand the point they are making, I do. One even told me "I do it just to keep things simple and not confuse people". Sheesh. So thank you for keeping it real, even for those that fail to understand. You can turn up the volume of sound (after recording) increases the gain (noise) of music as well....but some how in photography's digital age, this basic fact of ISO increasing gain / noise of light that has already been recorded (based solely on transmissibility of light through the lens and shutter speed seems to be elusive for many. Thank you. Your explanation is much appreciated. Well done! (Just an aside: I do believe back in the film days it was technically called ISO, but ASA - different standards governing body, but the point your making is spot on). Brilliant break down and the best video I've seen on the subject. I'm now a big fan! ...and now that I completed watching the video, You, my friend, totally ROCK!

i have learned more in 37 mins watching this than i have youtubeing for the last year liked and subscribed

For years, I’ve been so scared to shoot photos at night due to high iso and getting grain in photos, but after watching this video and getting all this information I’m now excited to go out at night and take some test shots/edit them. Thank you so much! 😊

Very rare these days that a photo tutorial show me something I don't know, but I actually learned a lot from this! If I'm being honest, I don't mind luminance noise in most images. I usually just stick to chroma reduction since that barely affects sharpness, and I'll even put more grain on top if the luma noise is high. I'll have to keep these tips in mind though if I really want to clean something up.

This is by FAR the best tutorial about sharpness, noise and noise reduction, I've seen so far !

Best noise explanation video and noise editing explanation video so far on KZfaq! Thank you

There are so many photo videos online that don't teach you anything new, but from time to time, you find one like this one! So helpful and clear! I learned so many useful tips in such a small video. Thank you !

Very good. I am just beginning bird photography (75 years old but still going strong!) with an old Canon t3i---600D--and a Canon 55-250 lens. So, I'm limited. But before I invest in a more appropriate quality telephoto lens I want to learn as much as I can. Your videos are extremely helpful. Very well presented and understandable. Thank you. (Also, I like that you get right to the topic and don't have a lot of blah-blah before the lesson.)

This HAS to be one of if not the best vids on photo enhancement, particularly in regard to sharpening/ ISO, I have seen in I don't know how many years of surfing the net and reading. THANK YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This just popped up in my recommended videos, now I see I’ve been doing my noise reduction wrong for the past 13/14 years. I will subscribe and look for more tutorials so I can learn more. This is an outstanding description of how to deal with noise, must be the best on KZfaq hands down. Thanks so much for taking the time to do this, I bet it took ages 😎

HOLY MOLY! I thought I was the only one using layers to reduce noise especially with nighttime photography. But this was an Excellent job of explaining the process and methodology. You've gained a subscriber. Thank you!

1st KZfaq Photographer I have found that I would actually join in a Patron Subscription. Fantastic work.

One of the best tutorials I've ever watched. Thank you for this.

A fantastically logical, well thought out video as usual, treat to watch and learn from. Thanks!

This was the most amazing presentation. I've been working with Topaz DeNoise a lot, but your masking approach is so superior and makes so much sense. You are my new, favorite youtuber....I will be following your work very closely in the future!

The thing about using the camera manufacturer's software to denoise first, then exporting as a tiff for lightroom/whatever - that's *golden*. Thank you!

This is the most comprehensive noise reduction video I've ever seen. Just in time for me to edit some wedding dance images with way too high ISO. Thank you for your detailed upload. I'll have to investigate your channel further.

Scott, this is brilliant. I never would have thought of doing that. I am planning to change my workflow to incorporate it!

Wow, this is a ‘must watch’ for every digital photographer; there’s so much misconceptions that you’ve cleared up in this one video. Thanks for sharing👍🏼👍🏼 Subbed😄

Scott, Fantastic job. The best I've seen on the net. In addition, explained in a simple, concise and intelligent way. Bravissimo!

you sir have saved years of me being sh*t scared of higher iso

A long video, Scott, but I stayed with it and pleased I did. Just started using a Z9 and I had already learned about it’s ISO invariance and so now avoid ISO levels between 100 and 500. 500 is my default unless I’m doing landscapes with a tripod. Not every image is worth the time you put into the kingfisher shot but the photoshop technique is very interesting and one day I’ll give it a try! I have LR, PS and Denoise so your advice is very helpful. Many thanks.

Nicely done.... probably the most comprehensive tutorial on noise reduction I have ever seen.... amazingly surprised by the fact that I was aware of most of the content, still was able to gain from it, I generally shoot at base ISO with controlled lighting and usually don’t have to deal with much noise issues, I have used photoshop layers magic for 25 years on this occasion it was the case of adding 2+2 to get to 4. As they say you never stop learning.....

it blew my mind how much i didnt know about ISO and noise... so good video, so informative, THANK YOU.

At last I find someone talking sense! For years I have been trying to teach/tell people this sort of thing... and stuff like EV is actually only about shutter speed and aperture and ISO actually has nothing to do with EV. ISO does, of course, affect the exposure of your image though! I have given up trying to teach that ISO is all about the gain and not the sensitivity of the sensor! You win some you lose some... ho hum... Great 'videa' (to coin a word) and perhaps I will simply send this link to those that ask in the future! 😉😉😂😂😂

Hi Scott, I am a bird photographer and noise is very important especially when I go to a rainforest or overcast conditions. I have been looking for a possibility to test run the fact on my Z9. Starting from ISO 64 to 10.000, I have captured series of photos with same aperture (7,1) (500mm f4 Lens) and changed only the shutter in every step to provide the same white balance on the photo-series. Btw I can share the results. - According to the diagram there are two important points to focus : 1- The noise level on ISO100 and ISO500 looks to be the same as nearly 1,45 2- The noise level on ISO400 and ISO2000 looks to be the same as nearly 3,35 Of course we are not able to test and prove with special devices but can make our own test to compare. The results are unfortunately not like in the diagram. Comparing photos taken in ISO 400 to ISO600, There is significantly more noise in ISO 600 than ISO400. When continued to compare with ISO 800 and the above, getting relatively more noises in every step that I go above. I can only agree "the noise in ISO 500 is slightly less then ISO 400". This is a good news for z9 users. At least one step gain is someting in hand. Comparing ISO400 to ISO 2000 is almost not possible and the results are far different like day and night. For sure 400 is much cleaner and with lesser noise. Although the diagram confirms to be the same but is not the fact and the case indeed. Of course the information and the data source you shared is defending an important argument. I agree it has a value of a news to share. But in the same way, such individual tests that we could make at home should also confirm and prove the argument issued. Above are my tests and my realities vs the website's information. On the other side if it was really correct, why would manufacturer NIKON give the options between ISO 500 to1600 as there would be more noise than ISO400. They would immediatly jump from ISO400 to 2000 in the settings. That would make sense. I can not blame the website for the other cameras. But Z9 is the highest available top level series of NIKON. It is extremely important and I respect you did right to share. If possible in your convenience, I would definitely respect to your tests to compare and share with us if possible. To be honest it took me only half an hour to put things together and compare. I am taking all the information you are sharing extremely important and serious. So grateful that you are sharing and posting all. All the best. Thank you once again Scott.

Most of the time noise is not as big of an issue as over exposed areas and lack of dynamic range in digital image files. Contrary to SLR cameras using film, DSLR cameras picks up details in darker areas better than brightly lit areas so I always shoot at -0.5 stop; slightly under-exposed. While this leads to slightly noisier photos, it also gives the added benefit of slightly shorter shutter times and hopefully sharper images as all my shots are handheld of things that move. I think some noise in images are fine, its part of the art. All the images in this video are totally fine without noise reduction, and you could probably produce fairly large prints from them and nobody would care about the existing noise. And thats the key: those you share them with enjoys your art without worrying about technical stuff. You, the photographer may perceive problems with the noise, but for everybody else it is a non-issue until you really cant make out anything. Life is too short to eradicate all noise in photos . This video shows some really great methods to reduce a lot of noise, but for most images, blown out areas leaves you nothing to work with. Where these methods may really come into play are if you are trying to resurrect old photos; digital photos from the 90s or 35mm film scans etc. You'd be surprised how noisy or rather grainy 100ISO film was, even when perfectly exposed.

truly this one of the most amazingly educational videos i have watched ever about photography . many thanks

best explanation in human language I've seen thank you very much

I don't know man. I don't know what to say... I saved this yesterday for later watch and I've just got home from an indoor events where I shoot lots of high ISO (capped at 6400 for my D700). I only own a cheap 24-85mm 3.5-4.5 from Nikon (still working on the faster 2.8) but cause of that I had to endure the high ISO. Man watching this is opened a complete new horizon for me, I also found out that NX Studio is FREE (I installed it a while ago to see if I can install a driver for my D700 so I can tether it with LR but it didn't work out maybe the cable is faulty. But this is simply gonna make most if not all of my thousand photos go wild

I watch a lot of videos and have been in photography for 35 years. You Sir have a incredible knowledge. Thanks for sharing

Outstanding tutorial. Thank you!
