Be sure to do some daytime testing yourself too!
Whether you are learning photography or are a seasoned expert, it's very important to know the limits of your gear! I run a lot of street photography workshops, and in most cases, the client is very nervous about shooting at high ISO during the day, for fear of compromising image quality. In this video we discuss how choosing a higher ISO can actually improve your street, events wildlife and travel photography.
Thanks for watching

We host workshops on fashion/beauty photography and it strikes me how many, even seasoned, amateur photographers don’t really understand ISO. For one, it is not a sensor feature, but a raw processor feature, that can be applied afterwards just as easily. It simply doesn’t affect the raw data. Just the live view, preview and jpeg. Fuji uses sensors that are calibrated, for most models, to ISO200 or ISO160. That is the native ISO and raw data is captured by a result of this native ISO, combined with the shutter speed and aperture. The set ISO on the camera will simply amplify that data to the required level for a correct display (either in live view, jpeg or the preview jpeg that is encapsulated in the raw data. The DR feature is basically boosting the ISO for live view and jpeg and then underexposes by 1 (DR200) or 2 (DR400) stops. That is why you can’t set a lower ISO than 320 or 640 (on a native ISO160 model). In raw processing in-camera the underexposed image is then boosted by 1 or 2 stops. The trick is that Fuji doesn’t do this linear, but they leave the highlights as is and use a luminosity curve on the mid tones and shadows. So, to achieve the exact same result in post, you can’t just use the exposure or shadows slider, but you have to use the curves tool. If you do so, you’ll understand that you can do this trick with every modern camera. Also the ones that don’t have a DR-like feature. For Fuji shooters, I can highly recommend Rico Phirstinger’s book ‘Fuji X Secrets’. Tip 61 to 70 explain all you need to know how to handle ISO on Fuji X cameras, or any other digital camera for that matter.

Thank you very much for this detailed comment Jacob!

@dirkpehrke9909 Год назад

It is wrong that it can be as well done in post. This is true for very high ISO values, but not in general. ISO is added prior to the raw. It is like using a higher gain setting on a mic preamp before recording. This can’t be done in post. So part of what you teach your seasoned amateurs is wrong. Iso invariance is more complex and the values differ between different sensors, but it is not true that you can shoot all pictures at base iso and whatever a higher iso setting does can as well and with equal results be done in post.

@jacobh5817 Год назад

@@dirkpehrke9909 I think you will find Rico’s book really revealing. Let’s take your analogy. The base ISO is the mic setting that is applied to the sensor by the manufactorer. Some sensors have two base ISOs, dual ISO, so two levels of mic amplification. This is baked into the embedded software, so you can’t change that. Two brands that use the same (Sony) sensor, can each have a different base ISO, depending how they tweak it. This base ISO is also the ‘gain’ that is applied to all exposures at recording. Regardless of the ISO you set on the camera. The only two variables that determine the amount of light at recording are aperture and shutterspeed. The ISO you set on the camera is the amplifier gain. It makes the music louder, but it doesn’t affect the recording. Just the playback. Let’s put this into practice. When you fix your aperture and shutterspeed and take the same image with different ISOs, you will have one ‘correct’ exposure and some over- and others underexposed. E.g., when the correct exposure would be at ISO200, the ISO100 image is one stop overexposed and the ISO800 image two stops underexposed. That can be easily corrected in post, with virtually the same result as the ‘ISO200 image’. That is what I (and Gareth) meant by ‘corrected in post’. Two stops on the exposure slider in LR acts as if you bring ISO800 up to ISO200. All that time the original image (the recording) remains at base-(or native) ISO and the set aperture/shutterspeed. You can’t change that in post. Modern sensors are usually able to record with 3-3.5 stops underexposure, but generally only 1-1.5 stops overexposure. That is roughly the same for all ISO-levels. Not just the high ones. So, for street photography, if you stay within that range, you can easily correct without adding too much noise. In your analogy, when you record too soft (underexpose) you can crank up the volume in playback, aka post. However, go to far and you will start hearing (or: seeing) noise. When you record too loud (overexpose) you dial-back the volume. However, its harder to correct an oversteered recording in playback (if at all). All that time the original raw image (the recording) remains unaffected. Recorded at the fixed base-ISO and the aperture/shutterspeed you decided on. PS. In my business (fashion and beauty for some exclusive brands) you can’t get away with a lot of exposure correction in post. I use base-ISO (usually 64 or 100) and adjust the amount of light.

@matchesder Год назад

Before the signal from the sensor is digitized, it is amplified by an analog amp. For example the X-T4 has multiple analog amplification values and therefore „dual native“ ISO. Because this is done before digitizing, there is a difference in the raw files. You can see the effect in read noise on the reed noise curves on photons to photos website. I found with DR400 I can recover more details from highlights.

I paused this video half way through, went and brought your zine and have just finished my first read through - loved it ❤ - some great shots but your candour in assessing each image and explaining your thought process as an evolving artist is what was most inspiring. Great stuff 🙌

@keithsandercock1412 Год назад

Good advice. For cameras 10 years old or older, high ISOs were an issue. For cameras produced in recent years, high ISOs are of little consequence, and as you have noted, can mostly be ignored.

@JaapKroon 2 месяца назад

I love street photography and I am also a concert photographer. Lately I am using auto iso in the M setting. As long as the exposure and shutter speed are set correctly, it hardly matters anymore how high your ISO is. I also often get away with photos of ISO 12,500. I shoot Sony for my concert photography and use Fuji for my travel and street photography.

@davidellinsworth3299 Год назад

I just simply don't worry about ISO on the Z6. Obviously for landscapes or any type of photography with a static subject I'll do things properly and shoot at a lower ISO. For street photography I just wouldn't worry. I think the majority problems come when people start raising shadows that are meant to be dark/black anyway (night time). You're obviously going to get problems then because there was f all light to begin with.

@GarethDanks Год назад

Exactly mate. People do seem to push shadows way to much in street photography. Thanks for watching Dave. Catch up soon mate

@thegroove2000 Год назад

EXACTLY.

@thegroove2000 Год назад

Shadows are shadows blacks are blacks. Why bother to try and reveal something thats not seen anyway confuses the f outta me.

@carlmcneill1139 Год назад

To add to what Jacob said, ISO invariant cameras can shoot at a low ISO and allow you to bring the exposure up in post without any effects. If you take pictures of the milky way at ISO 100 and then at ISO 3200, the noise should look the same in Lightroom when you raise the exposure of the ISO 100 picture 5 stops. There's 5 stops between ISO 100 and 3200. If you try to do this with a non ISO invariant camera (Canon) you will get a lot of color artifacts and your picture starts to break down. But you nailed it about aperture and shutter speed being the most important. ISO is added to the file after the picture is taken not during. Just like the film days, aperture and shutter speed are the main exposures in a picture. Back then the ISO was in the film and you were stuck with what film you had in the camera until they roll was finished. I have taken pictures with my z6 II of my daughter's school play at 12,600 with little issues. I have taken photos at night football games at ISO 10,000. Editing software keeps getting better and so do cameras. I don't do a whole lot of street photography but I don't let ISO bother me. I shoot in manual and I will use auto ISO if the light is changing a lot. I haven't used Fugi cameras but they seem to be amazing in low light to be a crop sensor camera.

@GarethDanks Год назад

thanks carl, great comment.. partly true about the iso lifting.. i think most invariant sensors are still 2 part.. eg 100-400 then 640-6400. I don't think you can lift from 100 to 6400 on any sensor yet.. maybe I'm wrong tho (since having my sony a7iii it may have changed)

@carlmcneill1139 Год назад

@@GarethDanks I think my z6 II is 100 and 640 ISO.

@T-Prime848 Год назад

Well for me as a street photographer I do not care about ISO Sometimes I shoot using 800 Or 1600 during day light Grain gives the photo a certain character The most important thing to get the right shot that gives me comfort

@SivertAlmvik Год назад

I have my auto-ISO presets set to 1/125, 1/250 and 1/500 on my X-T2, and all three are set to max ISO at 12800. I want to freeze the motion and shoot at at least f/8 (or higher). My thinking is, if someone points out "OMG! You shot this at 6400 ISO, didn't you!?" then it is not a good image (or the person is a weird gear head and not interested in photography as art). I've printed high ISO images up to A3 without anything noticable. Sure, if you press your nose right into the ink, you can see grain or high ISO artifacts, but who looks at images that close? (Don't do it. The ink will stain you nose and you'll ruin my photo!)

@gainde1137 Год назад

If you need to capture movement the shutter speed is the most important factor.

@kevinbatts2804 Год назад

The high iso shots on my XT3 are magical and a different element in my street photos. I love shooting at f4 thru f9 and I sacrifice everything else for it. With a small caveat if it's a print or client work.

@mikejay1130 Год назад

Why do you love that range? Very curious!

@dude157 Год назад

the thing about iso invariant sensors is that it doesn't matter if the gain is applied in camera before it's written to a raw file or if you apply it in post in lightroom. You will get the same result, that's the definition of iso invariant. What this means is you are better off under exposing an image with a lower iso to preserve the highlights, then recovering the shadows in post, than you are to boost everything in camera in the exposure with a higher iso. Like you say the real trade off of increasing iso is losing dynamic range. Increasing iso doesn't necessarily increase noise, as shown in your flash example. Noise comes from a low signal to noise ratio, which comes from under exposing the sensor. Iso is effectively a control that tells your camera to under expose because it will trade off some dynamic range for brightness. Which also brings out the noise in the shadows.

@larshultberg6972 Год назад

Thanks a lot. It’s a sunny day to day here in Malmö, Sweden and I will try out your suggestions

@Dplaysitcool Год назад

I made my bread and butter shooting in big night clubs. And was set on using 'natrual' light. Which needed high ISO. This was back when I used a Canon 60d! I would sometimes go beyond 8000... Once cameras moved on and high ISO still produced clean images. I literally don't care what the ISO goes up to now(within reason) ... There used to be a fear with photographers that you simply should NOT go beyond 100iso. Haha

@rutlegs Год назад

OMG this soooo applies to me! I think I pay so much attention to ISO because I learned photography on film... I've started using Auto ISO on my XT4 and it's slowly starting to sink into my thick skull.

@madalin934 Год назад

Glad you're back on YT, been watching your older vizios over and over to get my Gareth fix :)) Will check out the zines in a second, need to jump on the website now and hunt for spelling mistakes :))))

@Whatisright Год назад

Can get clean files on the XT3 at ISO 10,000. I prefer shooting higher ISOs because when the light changes I simply drop the SS and not get camera shake or a blurry moving subject. As much as we should care about image quality, the logistics of shooting is also important (to me). What's easier to manipulate without much fuss. Changing the shutter speed has less variables than changing either of the other settings. ISO is the set it and forget it setting, the others are what are used to be creative. On my XT3 the ISO and SS settings are changed by the front and rear dials not the top. I don't have to change my grip or move my camera to adjust anything. Literally just count how many clicks I go in one direction and adjust the other accordingly to maintain the same exposure if need be. If I don't have good light, sensor saturation will wipe out most noise so having that room to work with really helps. A proper light meter also does away with any guess work for my starting point.

@ashiqurrahman1469 Год назад

Thanks so much, this has been such a helpful video

@realniteart Год назад

Even with correct exposure and enough light, dynamic range of sensor is worse at higher ISO. It works with many but far from all scenes. I don't worry much about ISO, but I still set it manually to minimum required to get a shot the way I like it.

@kne321video Год назад

No concerned with going up to ISO 3200 on the X-T2 in the night. And not concerned about shooting wide open also. Speed is more important for the effect that I want in the picture. But you have to learn what speed you can handle while walking and standing still. Good light / daytime shooting even easier.

This is an excellent episode, well presented and thoughtful. I have come to a similar conclusion about ISO but without the rigor, experience and knowledge you have. My testing has been limited but with similar results. I should be more diligent. I have come to trust your insights on many photography issues. I recall when you first started your channel, being impressed with you compositions when I saw no reasonable compositions on the coast somewhere. Your street photography is inspiring, to me, although I have done little to explore that genre. Thanks for sharing. I appreciate your thoughts and insights.

@FiZ Год назад

I admit, as an event-photographer (concerts/nightclubs/etc), it took way too long to realize that you're talking about shooting in already good light 😅 Try shooting in very low-light at 12,800 and you'll learn exactly how much ISO noise can matter! 🤣 The cameras have updated to make those higher ISOs look way better than they used to, though.

@NickBarang Год назад

Lol. I am happy to let ISO float up to 3,200 with no real reservations. In fact, my Fuji XT-4 and XT-3 are both set up to allow auto-ISO up to 3200. I'm happy to control the aperture and shutter speed instead of ISO because there's so much flex with ISO now.

@GarethDanks Год назад

@jbairdexp Год назад

When I shoot concerts I'll crank the ISO up as high as it needs to be. Better a sharp, noisy image, than a blurry, clean one.

You know why it won’t let you shoot below 650? Cuz it’s just lifting the shadows. Overall this is a great video, but let’s see those tests you did on dr400 vs lifted shadows. The only thing I can possibly see happening is it’s got a different algorithm for shadow lifting than Lightroom does.
