​@@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.

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.)

[@AN-ii9pk]

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. Most viewers will notice out-of-focus and blur instantly; few will complain about noise. And as Simon pointed out, noise is now pretty easy to fix.

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 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.

[@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 point of the video is that if those are your only two options, raising the ISO is less problematic. Obviously we’re talking about situations with no other options (e.g., slower shutter will produce motion blur and aperture is already wide open).

[@PauloRibeiro9797]

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.

@@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)

When I started photography (60 years ago) it was all about film, and the standard film was 100 ASA (which became ISO). It was based on normal lighting in the middle of the day for shooting at f8 and 100th second. 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. Digital changed everything.

[@davidgreus3041]

32 sounds crazy cool!

I started photography 30 years ago, just before digital entered the world of photography. I was always using film 100, but that limitation helped me to fall in love with my aperture settings.

[@evmanbutts]

I learned and "grew up" using a DSLR but could not stand the auto or "creative" settings, so I'd always just shoot on manual.

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.

[@redneck472]

I just started photography and was following the "keep ISO as low as possible" rule. I kept getting angry because my photos were blurry. I have shaky hands and my shutter speed was very low. I'm glad that you've taught me to not be scared of higher ISO's and realise that they go that high for a reason!

[@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.

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.

[@iviaverick52]

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.

[@digitalcity1]

Sensors have a 'native' ISO so setting below that also reduces dynamic range. As a cinematographer I work to the camera's native ISO as much as possible.

Do some tests. Shoot with plenty of light at 100 iso, and then 800 iso. You will see a marked difference in grain/noise. What you determine is "satisfactory" is entirely subjective.

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.

[@shutterbird13]

I just want to say THANK YOU. I just started to get back into serious shooting with a camera. I was relying on my cell phone camera for the last few years because my schedule and health conditions make being out during daylight hours a fairly rare thing for me, and my 7D just didn't have the low light capability I needed. On top of that, shooting in low light exclusively after being a mostly daytime shooter for over a decade? It's a whole new learning curve. Taking the taboo and guesswork out of ISO settings has been a sanity saver. My new R8 is set to auto ISO now, and I have control over everything else. So seriously... Thank you so much.

During the film days, my brother and I did wildlife and landscape photography in the Rockies. He always used the lowest ISO (ASA?) possible while I was overjoyed when ISO 400 appeared. While my brother kept changing his film based on the subject, I exclusively used 400. That's when he gave me the nickname, "Old 400", and I've used that moniker ever since. Thanks for this fine training, Simon.

Only go to the lowest ISO "IF" you have enough lighting to do so. Most important is getting the shot with the lighting you have. Your information is absolutely correct. Thank you for bringing the subject for newer photographers.

[@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.

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! :)

[@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.

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. Most pictures look noisy because of wrong focus or wrong shutter speed.

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.

I used to be afraid of using higher ISO values, so I often kept my ISO at 100.

Now, I either set the ISO manually or use auto ISO with a limit. You are so right about this

[@angelsepulveda9211]

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.

[@williamfields7225]

A note; the organization that invented 'ISO' is not the International Standards Organization. It is the International Organization for Standardization and 'ISO' is the Greek word for equal. The idea being that an ISO standard is applied in the same way across an industry. In our case, it is the light sensitivity of the sensor on any camera. Before digital, it was the sensitivity of the film one used. Your SIM card in your phone is an ISO standard, as are the size and layout of your credit cards.

[@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.

Auto ISO lets you choose your aperture for the actual depth of field you want, the actual shutter speed you need for the amount of motion blur you want, and lets the camera fill in the blank for the ISO.

It helped so so much with my photography. I can adjust the limits throughout the day and do not have to care about it "in the moment". I love bird photography and it is so lovely that I can just set the limit to 3200 for day shooting, 12800 for early day shooting where conditions are poor - and I can just shoot away. Sure, it sometimes tries to over shoot, but as mentioned in the vid - a photo is much better than no photo at all.

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.

@@Cayoalbuquerque My bad then. I misunderstood your comment because we often refer to the noise floor when we talk about SNR, although you are correct that you can still use the term SNR when talking about background noise, but it's not as common. I am sorry if my comment made you upset.

Excellent! ISO also comes from the Greek word "isos". As a film director, my dad taught me the original ISA standard as well as ISO's. The myth of ISO 100 actually stems from the film era which was a challenge for young reconnaissance photographers in WWII, like him. He and Charles Scripps served together and were very aware of film's temperature/chemical properties. With the advent of charge coupled devices (CCD), which all modern digital cameras are based, everything changed in the ISO world, as sensors work on a Nyquist fourier transform method when it comes to noise. As Honeywell, and later Sony, improved these devices, ISO settings expanded greatly. Whether filming at treetop at 275 mph in a P-38 Lightning, or high up in a heavy bomber, it was a real balancing act to obtain usable still/film footage. If you want to know more about the latest digital sensors, I suggest checking out Pawel Achtel, ACS, and his new 9:7 format digital based equipment.

Seeing this video, I feel like I just got released from ISO prison

[@RememberTheTrees]

From ISOlation, you might say

[@lloydsshadow5903]

Same. My photographer life so far has been a lie... and I am now free.

In fact, Simon, I've been a hobbyist photographer, aspiring to become professional since 1986, when I bought my first SLR. Back then I used Fuji Velvia ISO50, because I had this advise on "low ISO = the best images" (and Velvia was indeed a great film, no doubt), but as a nature and wild life enthusiasts usually dealing with low light, I only wasted a lot on film rarely getting a decent image. Now in digital photography my limit has been ISO 400 due to the same poor advice, keeping me in failure and frustration all the same. Now, Thanks for your wise advice and teaching, I am already having renewed hopes in my photography.

I got into this conversation with another KZbin photographer the other day. They were talking about "common mistakes new users make" or something along those lines. I told them that they (community, not just them specifically) needed to start rewording or rethinking what they were teaching others. High ISO isn't inherently bad and it's more to do with their usage of available or artificial lighting that was definitely important. But...not everyone, including myself, get everything right based off experience, but on what they're been told. I learned a lot of my skills the hard way lol

[@jekjr1957]

I am forever thankful to you for teaching me this. I was clueless because I was alway taught to keep that ISO low. I set my camera in Manual with ISO in automatic and boom everything changed.

Why no one told me about this before! I went through the whole season of northern lights, underexposing (still at like 1250 ISO) and getting crazy noise. I just made a quick test in dark room, and can confirm bumping up the ISO does work. Thank you very much for your advice!

[@simon_dentremont]

Glad I could help!

[@Qlicky]

Are you trying to say that higher ISO ends up with less noise assuming both shots are taken in identical conditions?

[@tpaine666]

When I discovered this tip years ago, it changed my photography! Now, I barely notice the ISO on my screen, just get the right shutter speed and the right F number and the rest is easy. Great tip!

[@MINECRAFTandSEB]

A much better tip for using auto ISO is using exposure compensation. Many cameras do tend to want to create brighter images then we seek, if you use any auto setting and want to have less bright out of camera photos then exposure compensation is your friend. That being said, I shoot entirely manual.
