How have I never been taught this before! 🤯 I was always told the high ISO created the noise, and that it was better to brighten in post. This is a real game changer. You are such a gifted teacher, Simon. Thank you 🙏

[@Light2lens]

It does and doesnt, alot of the noise is created at high iso is interference in the sensor and body, most cameras today are fine to 3200 for stills and 800 for video, its more about understanding dynmaic range, 0 to 255 values true black and true white.

[@drewmorrison]

Yeah high ISO really only ruins low light shots. Those shots were it’s dark and you want deep shadows. I realized this once when I turned my ISO all the way up, aperture to F16 and shutter speed fast and noticed it took a normal picture 😆

[@TimGreigPhotography]

High ISO does creates the noise.

[@HHamilton-kw1zx]

You were taught right. This guy is posting counter culture for view counts

[@Case_]

On top of adding noise, high ISO also noticeably reduces the dynamic range. That's part of why you should learn how your camera behaves and set it up accordingly to produce the best result for any given scenario. Carelessly bumping up ISO will not always give you the best results, but neither will keeping your ISO too low. (Also, speaking of shooting at F/16, don't forget the effects of diffraction at higher apertures, making your images softer than they could be.)

[@EZ-lj3hv]

[@EZ-lj3hv]

​@@zetaphotography6548 I am using the Fuji X-S20 (APS-C). But I have come to realise my pictures are a little dark with Auto. Now I guess it would depend of the software of the camera too. I am using version 2.0. It works most of the time and it is true my pictures have improved in quality, and it is easy to bring some exposure post processing, but sometimes you do have to increase or decrease the ISO manually. Which is not big deal.

[@pennymercer4158]

Haha me too with the auto ISO in manual I was sick of pressing the ISO button and rotating the dial to change it all the time

Good video. The basic message, which I've believed for years: far more photos are ruined by out-of-focus subjects (resulting from insufficient depth of field) or motion blur than were ever ruined by excessive noise.

What crasy ISO numbers !!!! I used to photograph with Kodachrome 64 (only 64 ISO) or Fuji Provia 400F or 400X (400 ISO). For mooving subjects in bad lighting, I had to turn to B&W with Ilford Delta 1000 (pushed to 3200 and developped in XTol, even then it was quite grainy)... You should really hold the camera stady with Kodachrome 64 if not using a tripod, and it was either no depth of field or not enough shutter speed, often both lacking (but what a great film non the less)... but...

I must tell you something: This is the first time I've heard this advice and I really understood perfectly how the signal-to-noise ratio applied to sensors works (since I'm an electronics graduate as well as a photographer). Everything became logical after your explanation. In addition, the new denoise function in Lightroom had already prompted me to increase the ISO in my photos, with amazing results. I, who had even forgotten about the automatic ISO function on my Nikon, went and started using it in conjunction with the manual exposure controls. I really liked the results and I didn't see any photos where denoise was essential. This post of yours deserves to be printed out and put up on my wall. A big hug and sincere thanks.

[@simon_dentremont]

@@PokerGuts On my astrophotography cameras there is no ISO, just a slider called « Gain ».

[@johnquaffel110]

However I feel your explanation is introducing the misconception that gain/iso balances exposure and one can trade one for the other easily. However, ideally, just talking about a satisfactory SNR (not taking artistic factors into acount, e.g. minimizing exposure time), exposure and gain reach a minimum below which higher gain levels cannot compensate low exposure. Which is, because signal increases linearly with exposure but noise only with square root. Whereas shifting signal+noise levels with gain are both linearly proportional to each other. Or did I get that wrong (I just know from my time working with detectors for electron radiation, we needed to consider just that)

[@Dreyno]

I moved to auto ISO for most handheld shooting years ago. I was reticent to use auto anything but I realised I was missing potentially great shots all over the place in my quest for low ISO, super detailed images. Now I stick with auto ISO unless it’s a landscape shot on a tripod. A sharp shot with ISO 800 is better than a blur at ISO 100 every single time.

[@j3nn3s]

Similar here: When using manual flashes, I use a fixed ISO. Otherwise I use the custom settings for quickly switching between the "people" setting with a shutter speed not slower than a 1/200th of a second and whatever ISO necessary and other frequent use cases. It doesn't help the foto if it's virtually noise free but OTOH the person in the image suffers from motion blur.

[@wolphin732]

For fast shots... found my camera does 100-25600 with acceptable grain/noise, so have auto-ISO set to do it. Did an entire convention without touching my flash at all without much issue. One less thing to have to deal with when taking photos. Also use Aperture priority, and back button AF, with Continuous auto-focus mode, and works well.

[@Dreyno]

@@wolphin732 I’ve used back button focus for the last 7 years. Would never go back to focusing with the shutter. I keep mine in manual mostly and select the aperture and shutter speed I want and let the auto ISO deal with the rest. If the ISO is creeping up a bit more than I want for the occasional shot, I open the aperture a bit and use a slightly slower shutter to compensate.

[@andystephenson1584]

I never used auto ISO until recently. Vast improvement! For general hand held shots I mostly use auto ISO, stop down one stop and, if appropriate, bracket exposures. Manual ISO is just for specific cases.

I grew up in photography. My father was a great photographer. I became a lab manager for other photographers. Back then we used film and if you used anything over 400 ASA the photos would have a lot of grain or noise in them. So everyone would try to shoot with 100 , 64 or 25 ASA. ASA changed to ISO in 1974. People think that ASA was for film and ISO was for digital, but this isn't the case. If you have a film that is ASA 400 or 400 ISO, they have the exact same light sensitivity as one another. But you probably already new this. Everyone thought that digital would never be as good as film. I'm guilty of this. Since I started shooting wildlife I quickly found out that auto ISO is the way to go! The information you provide is priceless! I look forward to your videos, they have taught me a lot. Thank you!

[@BillFerris]

A good approach is to choose the widest lens aperture (smallest f-number) that delivers an adequate depth of field and the slowest shutter speed that will freeze movement to your liking without blowing out important highlights. Those settings not only control two important creative elements of a photo, they also determine exposure and the amount of light used to make the photo. From there, choose an ISO - or delegate that choice to the camera through auto ISO - that delivers an image having a pleasing lightness. The more attention given to those creative settings of f-stop and shutter speed, the higher the likelihood you'll make pleasing photos...at any ISO.

[@jack002tuber]

Hope you have shake reduction. I think mine adds about 3 stops or so. Experiment to see what shutter speeds you can reliably shoot and then up the ISO when needed.

To be honest, old cameras were very noisy back in the day. Before 2010, there were many cameras which were noisy as hell even at ISO800 and 1600 was the limit. There werent so much auto settings for ISO and minimal shutter speed, so its not only about learning the lesson of ISO. I learned to shoot at very high ISO through birding because you have f/5,6 - 6,3 apertures and need 1/1000 or higher and have to accept what the camera tells you and you cant and wont buy a 600mm f4 lens for a hobby to get around this a little bit.

I still use +1000 ISO for astro photography, but mostly for the moon and very few planets. I was never, nor am I currently afraid of high ISO, so when I learned that most KZbin channels tell you to stay between 100-400, I thought they were crazy. This is a refreshing change of pace, and definitely the reason I stick to your channel for inspiration and insight.

[@dominicwroblewski5832]

The real trick is taking the time to learn the limits of your camera in terms of ISO performance. It is important to know where the tipping point of a camera is in acceptable high ISO noise. Once you know the upper limit, you can set the ISO range for using auto ISO. In terms of cropping there is an old adage that states " if you think you are close enough, get closer".

[@leemarkowitz4709]

His point is that there is no limit where you’re better off just underexposing the shot. If you can create more light by adjusting the shutter speed or aperture, that is sometimes preferable. If you cannot, then you must raise the ISO as much as needed.

[@stickgarrote8582]

The upper limit comes from what the image is for. If you’re just shooting for your own enjoyment, there is no limit but when you work for a client, you have to know what the requirements for a usable image are. Sometimes it can be flexible, other times there’s a hard limit and you have to plan your gear accordingly.

[@leemarkowitz4709]

@@stickgarrote8582 That sounds like situations where the lighting is too poor to produce a professional image, not situations where underexposing the shot is better than raising the ISO. That’s the lighting exceeding a limit, not the ISO.

[@Case_]

The simple truth is every camera absolutely *does* have an upper limit where raising ISO *will* produce worse results and as such this point should only really be crossed as a last resort and certainly not without consideration, and that many cameras *do* use auto ISO in a way that raises the ISO way too much way too quickly for the intended result, increasing the noise and decreasing dynamic range as a result while gaining nothing. So as always in photography, if you want to get the best results, learn to use your camera to its maximum potential and know its strengths and weaknesses inside out so you can take advantage of the strengths and avoid the weaknesses. Which is photography 101, really, and applies to any camera you'll ever use, be it a simple point-and-shoot (or camera phone) or an expensive full-frame DSLR with lenses that cost a small fortune.

[@leemarkowitz4709]

@@Case_ So you’re saying it is better to underexpose and brighten in post-processing than raise the ISO beyond the alleged limit?

The sensor dynamic range decreases at higher ISO, it's not just the noise and SNR ratio. Having said that, a lot of full frame cameras retain more than satisfactory dynamic range until ISO 2000, even ISO 3200. This is more important for landscapes. In regards to noise, what you say is completely accurate.

Dynamic range may decrease at higher ISO, but an under exposed image with "high dynamic range" will still look worse than a properly exposed image.

The only other option was 400 ASA film for sports, or if you were using transparency film (which was the best by far) you could get 32 ASA film that was great for anything where your subject was static.

I usually carried two bodies because the one with the 25 in it was unusable so much of the time because of it not being bright enough to shoot without a tripod. It's nice now not having to go through 24 or 36 exposures to finish off a roll of film before you can change the ISO.

[@hotcoffeeamericano]

Basically, the ISO from a flim camera and from a digital camera is not the same and not comparable. My mindset was stuck in the film era, where we would prefer to shoot 100 ISO and below as 800 ISO film was just too grainy. We have come a long way in digital photography. Thank you for this video.

[@Ahmeni]

@@joel6376 Exactly. On my first two digitals I actually went to 50 and 60 as much as I could. I used tripod (sometimes as monopod) A LOT. IIRC early dSLR's could go ISO 400 MAX. At resolution of 3 Mpix. Before Nikon D300 you could pretty much forget about clean nightime shots, because even with tripod and bulb mode, sensors ran hot and therefore noisy. And unfortunately digital noise exists also, maybe even more, in colour, while film grains is only in luminance. Yeah, today I can shoot ISO 3200 with my phone, no problem. And of course you need to understand exposure time and your subject, because shooting landscapes, or even more waterscapes and infrastructure, is totally different from shooting wildlife or sports. In the first case you sometimes use ND filters to make exposure longer on purpose.

It's amazing how big the difference is between a KZbinr and a real photographer! Flawless video, congratulations! As I leave the studio, i set aperture priority, auto-ISO and auto-shutter speed with manually selected minimum value. The latter eliminates motion blur (e.g. I don't let it go below 1/500 in auto-mode), but if suddenly "too much" light hits the sensor (light levels are constantly changing in an event shoot), the camera can instantly increase this value for the correct exposure.

Great stuff. I'm a wildlife/landscape photographer and can confirm I've gotten some great shots at crazy high ISO. I once shot a barn own in the middle of a snow storm an hour after dark at 12,800. That was years ago before the huge improvements in noise reduction that have improved it a lot. Now I don't generally go too much over 3200, I heavily prioritize shutter speed and aperture on most shots. One thing that was very helpful to me in the beginning was guessing the correct exposure settings - then seeing how off I am based on the camera auto-settings, then also really understanding metering and range pictograph. It all really comes back down to understanding light then applying that to how a digital camera captures it. If you've never dived into how camera sensors work - it is very helpful. I will say video is less forgiving - but as far as photography goes, use that ISO! :)

It's really interesting, I'm an engineer who studied sensors (mostly acoustic ones) for 5 years and you're definitely right.

I must try higher ISO.

I have never had any formal training on ISO / Shutter Speed / Aperture, and just recently I finally bought a camera and started taking my hobby more seriously. So I've never been told about shooting in 100 ISO.

This video has helped correct a few ignorant mistakes and makes me feel a lot better about my wild life / nature shots

[@ailivac]

I realized years ago that motion blur is usually much worse than noise, so I turn up ISO as much as I need to to keep exposure times short enough. Especially with modern 16-24MP sensors... even older 12MP cameras. If you're asking these questions you're most likely not printing or displaying any of your photos big enough to see the noise.

[@skakdosmer]

I learned not to worry too much about ISO back in the film era! In my country (and possibly elsewhere too?) the newspapers stopped using film and went fully digital all at the same time. (I don't remember what year it was). This meant that the camera stores had a big surplus of 800 ISO films that they could no longer sell to the press photographers. So these films suddenly became cheaper than the 200 ISO films that we amateurs usually bought. And I got great results with ISO 800! Noise was much less of a problem than I had anticipated. It took me some time to fully understand why this was so, but using higher ISO was a good lesson.

Best explanation for ISO Simon. When i started i came from landscape photography and ISO was hard grained to be 100. But these days, the noise removal apps, having more control of shutter speed to nail the shot and seeing the difference of not having the good speed for action has shown me proof that i had to let it go awhile ago, so happy i did. Excellent example of the seascape and landscape action shots.

This is refreshing to hear. After 25 years of photography (and also having a career that involves signal and image processing on a far more technical level) I came to the same conclusion.

It is also becoming less relevant as newer cameras have better noise cancelation internally and de-noising and sharpening algorithms are getting batter by the day.

[@Cayoalbuquerque]

The gain knob analogy is absolutely spot-on. In audio recordings, it works EXACTLY like that. Every room has noise, but bringing the gain knob higher, you make it more evident if there's no clear signal being sent to the microphone to increase the signal to noise ratio.

[@hampuspetersson8363]

It depends if you talk about post or pre gain. The pre gain or "gain staging" as it is called does not raise the noise floor, only the input signal, thus creating a larger signal to noise ratio. Changing the post gain or volume however affect both the input signal and the noise floor, making the noise louder if turn up the gain for the entire recorded track.

[@hampuspetersson8363]

It also seems that you are confusing the noise floor with the room noise. The noise floor comes from the electric circuits inside of the recording equipment and is not affected by altering the pre gain, the room noise does.

[@Cayoalbuquerque]

Nope. Never mentioned noise floor. Only talked about SNR. And it is precisely what I described. You raise the gain, you get more audible noise if there's poor signal to noise ratio. That's exactly what I said. The room noise can be more apparent if you raise the pre-gain. The noise floor wasn't even being mentioned since it's related to circuits. It's as simples as that, you get poor SNR if that's no clear signal to be received by the microphone. Just the same with the camera. If the landscape is too dark/poorly lit, you have low "volume" signal entering the sensor, therefore, you get noisier images. The noise is always, and I mean always (not "often"), more apparent if you don't have a clear signal entering the microphone. You can test it. Raise only the pre-gain to as high as you can and don't emit any sound. You will hear the noise become more apparent as you turn the pre-gain knob to a higher. position. You are talking about entirely different things than what I described and making assumptions out of thin air. I said precisely what I said and not what you assumed I meant to say.

From what I learned you prioritize aperture and shutter speed according to the subject and adjust ISO accordingly as long as the noise level is still acceptable. Aperture = to get the target depth of field and hyperfocal distance. Shutter speed = to get the proper speed to capture. still, slow. or fast moving subjects. There is a limit where you just have to stop increasing the ISO because of the noise amplification and artifacts it produces and you just have to with slightly change/compromise the ideal shutter speed or aperture to get a balanced result.

[@Artfulscience1]

Studying cinematography really deepened my knowledge on ISO as well. In the cinema world, lower ISO shots have the dynamic range allocated toward the shadows while higher iso shots allocate the dynamic range to the highlights. So for low light scenes it’s actually MUCH better to shoot at lower ISO’s many times, because there will be significantly more detail in the dark shadows. This does mean you need to light accordingly though. Still the same principle applies, you can’t starve the sensor of light. as long as there’s lighting hitting the subject and you’re not trying to make a black hole visible, higher iso settings aren’t the end of the world

[@homewardboundphotos]

ummm... no.. this is backwards. lower iso increases the dynamic range in the highlights, and the shadows get crushed because of lack of light. higher iso will over expose the hilights reducing their dynamic range and bring out more dynamic range in the shadow, which can be pushed back down in editing. cinematography requires you to keep you shutter at half the speed of your frame rate to maintain 180 degree motion blur, so lowering your iso in a dark environment will always make you footage darker in the shadows and introduce more compression artifacts and lose you dynamic range in the shadows.

[@erikpeterffy7552]

@@homewardboundphotos That is completely wrong, and @mikemarch416 said it right. When shooting video, you get more detailed highlights at higher ISO values because the camera "sacrifices" the dynamic range of the shadow areas to preserve highlights by "elevating" the dynamic range window (making the shadow areas noisier). You can see this in action in this video, along with charts: kzbin.info/www/bejne/m6rMh52Kp6p4mNk It's no coincidence that, for example, S-LOG starts at ISO 800, you can't set it any lower than that.

[@homewardboundphotos]

@@erikpeterffy7552 uhh what, this video you linked has exactly nothing to do with whats being talked about and is irrelevant.. you need to think about this. why would increasing the iso, and pushing the highlights closer to clipping preserve them? you're pushing them closer to the end of the dynamic range of the camera. making the image darker (lowering iso) preserves detail in the hilights. making the image brighter (raising iso) preserves detail in the shadows. log starts at 800 because it's a reverse s curve and since shadow detail is harder to retain than hilight detail, the curve favours higher iso. that's the reason. The camera doesn't "sacrifice" detail in the shadows at high iso. it just makes the shadows brighter, which is the exact opposite of sacrificing detail in the, which is exactly the point of slogs reverse s curve, because the mp4 codec it records is lossy and throws out data closer to the blacks and whites. don't even start man, i make 6 figures, have 50k worth of gear, and a 5 series bmw because the photo and video works that i do. I know what i'm talking about.

[@erikpeterffy7552]

@@homewardboundphotos You are completely misunderstanding the concept of dynamic range. Increasing ISO doesn't make anything necessarily brighter, as you can achieve the same exposure at ISO100 and ISO6400 by simply using a faster shutter speed, narrower aperture or ND filter, so you don't push anything toward clipping. In the linked video you see exactly that, and the uploader literally talks about why you have more stops of dynamic range toward the brighter part of the image at higher ISO (he even encircles it for you in the diagram). Study the figure carefully at 1.34. There it is in big red and blue lettering what I am talking about. 6EV vs 8EV. As for the second half of your comment, well that gave me a good laugh.

The reason he's not just lowering the ISO in the camera is because 800 is as low as slog 3 will let you record. Record the image DARKER, retain detail in the HIGHLIGHTS. Same ISO, lower brightness (because of ND) = more detail in the highs. And guess what dumbass? The same works in the darks.

[@wildfire60]

This explains something that I have been experiencing. When I have chosen to shoot something at 1200 or 1600 ISO I have often found that it has less noise then when I shot at a lower ISO. That's probably because the lower ISO was underexposed where the higher ISO was easily properly exposed and thus less noise shows up. I'm glad I watched this. It explains a lot.

[@gabrielex]

This greatly depends on the sensor. Newer (and expensive) cameras have cleaner sensors, but try high ISO on some camera from 10-15 years ago... You can clearly tell which picture was taken at higher ISO settings when both exposures are correct and comparable, the higher ISO one will be more noisy. Also theres the consideration to be done about so called "native ISO", those are different for each sensor.

They're not cleaner, the do the noise reduction on chip. It's just well hidden by the high resolution.

@@shueibdahir They're cleaner AND they do noise reduction, some of those quite aggressively (which I dislike), but even without it they're generally cleaner if you exclude the super high density sensors.

@@shueibdahir they are much cleaner. I own a A7R4 and an IQ3 . There is no comparison

[@shueibdahir]

@@justinoff1 High resolutions and noise reductions seems cleaner to you but shoot prores raw and you'll see what i mean

[@justinoff1]

@@shueibdahir pro res raw ? We're talking about still cameras guy. Motion is an entirely different thing

camera drone pilot here. My people need to watch this... WOW. thanks!

[@alasdairmackenzie905]

Thanks for explaining this so well Simon. For wildlife, I now almost always shoot using Auto ISO, usually with an upper limit of 6400. That leaves me free to choose my shutter speed and aperture as appropriate with no need to worry about the changing light as I move my camera around to capture whatever appears and where.

I just changed from my old and, frankly speaking a bit abandoned Nikon D90 to D780. On D90, as wonderful entry camera it was in its times, anything above ISO640 was barely usable and using the lower was usually the better. Now I have to change my mindset and drop mental limitation of using higher ISOs. Thanks to this clip, it will be easier. Much appreciated!
