    • From what you've said about noise being cause by too little light on the sensor, it makes me wander if I would be better off OVER EXPOSING an image, then I could crush the image slightly in post and expect to see much less noise. Am I on the right path here?

    • ⁠@@simon_dentremont According to your graphic image in the video, at 2:56 you show an ISO amplifier after the sensor. The signal to noise ratio is established at the sensor. Starting at 1:40 in the video you said that the aperture and shutter speed are the only way to affect the amount of light on the sensor. If I understand this correctly, then over exposing an image can only be done with a change to the aperture or shutter speed. Is that correct? Once the signal to noise ratio has been established at the sensor, any change to the ISO is not going to improve the image in the camera, right?

  • I used to be one of those guys that would only shoot at extremely low ISO's. But I missed so many wildlife shots that I knew I had to try something different. So I tried shooting at manual with auto ISO. It was a game-changer. I was surprised to how well those shots shot at 3200, even 6400, cleaned up. I am no longer afraid of high ISO. When I can use base ISO I do. But by loosing my fear of high ISO, I am a much better photographer.

Ran it through Denoise and it looked like ISO 100. Let's hope Adobe keeps shortens processing time - I can't justify the cost of an RTX 4070 for these few pics - but wouldn't it be fun to get them done in under 10 seconds!

  • Thanks Simon, the last video and this one as well are real eye-openers. It’s better let to the camera use ISO to compensate for lack of light than underexpose and try fixing it in post. If the high ISO photo is noisy, the underexposed photo with lower ISO will suffer even more from it. I have fallen into that trap way too often. Also: There is a too strong emphasis on image quality rather than quality images (and yes, I have stolen this from James Popsys).

  • Freeeedom! You have released photographers out of "ISO Prison." Back in "analog days," you chose a film at a certain ISO (or ASA) because of the shooting conditions you expected to encounter. If you needed to compensate for low light, you chose a film with a higher ASA (or ISO), and vice versa. You generally had more ISO range options with black and white film. If the light you encountered didn't match your expectations, you could often end up in trouble. I "solved" this issue by sticking to ISO 400 Tri-X film and keeping a couple of neutral density filters ready if the light was really bright (yeah, grain could be an issue, but not if you weren't shooting wall-sized prints, and photos earmarked for publication would be screened anyway, so it didn't really matter at all!). Color film -- the Kodachrome or Ektachrome slide films I used -- had by today's standards, very low ISO ratings. Modern digital cameras have set us free, but we didn't even know it. Thank you for this outstanding "master key to the cellblock." We won't tell the prison warden. Ssshhh everyone! 😎

    • Typical amateur post. I was a pro photographer over 50 years, there indeed was no digital photography in my time. I started out as assistent photographer for the world famous Maria Austria (google her), all work was stage, ballet, opera.....the answer was, we used mainly Rolleiflex, no 35., films were Ilford HP3, which we developed at 24 c, and 8 minutes. We had no grain.As this hard working lady, had a modest income, I decided to become an advertising photographer after first also working as an assistent in one of the best paying Stdio's in Amsterdam. Later, when I thought , I learned enough, I started my own studio, smalles size was my Mamiya RZ67, and standard used 4x5" view camera. Most asa film I used was 65 ASA. The answer then was to be found, in the camera size, not the film. One could only succeed, when you educated your self to become a real pro. Not many succeeded, only a few got enough work. There were many amateurs bragging I can do it as well. Until they got a real assignment, the it became a different story. They called me, asked me if they could use my studio, which had 12000 watt per second flash. The were clueless, it made me weep.

      @cirrus1964@cirrus19643 ай бұрын
    • So true. Back then if you 'pushed' 200 ASA to 400, that was it for the 20 or 36 shots on the roll. What a luxury to now be able to switch ISO for any shot. Furthermore, the higher grain looked like concrete, besides having limited dynamic range and you couldn't do much to improve things afterwards; post processing didn't exist. Ansel Adams was once asked about modern advances and he said he'd use whatever was available to give him his desired end result. Another photographer who saw great advances was Wm Henry Jackson, who used window panes and his own chemical emulsions to get photos in the 1860's that were pivotal in the establishment of the US National Park system. He lived nearly 100 years and saw the arrival of color cinematography before passing. Amazing.

  • Totally agree. I find it helpful to think of aperture and shutter speed as “controls”, while ISO is an “indicator”. You set the first two as needed to capture the shot, and use ISO (or auto ISO) to enable the desired exposure. If you need a high ISO, that’s an “indicator” that you’re light-starved.

  • The more I learn about digital photography, the more I realize how similar the process is to music production. Many of the lessons I learned in music production carry directly to photography: microphone sensitivity(sensor), signal to noise (photographers literally call it noise, like audio noise), preamps, analogue to digital conversion, gain(ISO), post production, etc etc. Fun stuff!

    • I have noticed this, too. Blown out whites is practically like clipping the audio. You won't recover anything beyond the clip even if you turn down after, and it is distorted. Crushed shadows/blacks is similar to having the recorded signal far too low and you have to crank the level to compensate which raises the noise floor and introducing noise into the product. This can sacrifice the quieter nuances of an instrument. Raw files for better dynamic range much like a 24bit wav. While jpeg compression CAN be similar to over-compression on the master bus where you can lose clarity and dynamics OR lower bitrate renders. ISO being the "gain," that which will raise the noise floor also killing dynamic range. Shutter speed and aperture can be similar to mic angle and distance. Get the mic angle/distance wrong and things can get out of focus(pushed back in the mix by adding more room or losing the highs). Very similar to the softness introduced by slow shutter or failure of setting the proper aperture for focus. Still easier than producing metal genres, though. LOL

    • ​@@icaanul the analogy goes even further in the 16-bit days - excessive rounds of math due to EQ and compression would create the equivalent of banding (like someone going bananas with the curves control) which resulted in an undefinable yet audible degradation of the sound.

  • Another Master Lesson. Something you said in a previous video has stuck with me. "Edit for Story". It is so much more important than perfect sharpness and perfect photos. I shoot mainly at sunset because the herons I shoot are the most active and most interesting at that time of the day. I generally need to shoot at a higher ISO because the sun diminishes every minute. The story comes first, and then the quality of the photo. And yes, Topaz has been a game-changer. This video was incredible. Thank you so much for being such a great teacher.

In wildlife photography you're very rarely shooting stopped down, and if your camera is ISO invariant or close-to, most of the time the only real variable is shutter speed, so techniques on how to drop that with the kit you have really become key. Sometimes you just have to accept that you don't have enough light for a shot.

  • In my first-year of photography, I was told to use ISO 100. So I stayed on iso100 religiously. For landscapes, it was fine. For portrait photography with flash, it was fine. But for running and gunning doing concerts, events, weddings, wildlife, and bird photography. Especially birds in flight! I only use auto ISO and cap it off at 12800. If I go back to the first-year photography, I had so many images lost due to autofocus not working and getting blurry images from either that or the fact that I had to use to a SLOWER shutter speed. Now that I use auto ISO, I have a very, very, very high success rate. For instance I shoot on the Canon R5 and I have my first wheel for shutter speed, my second wheel for a picture which I really never use because I'm on the lowest setting the majority of the time to get more light, and most importantly my third will because I'm on auto ISO is dedicated to exposure compensation. So the wheel on the back of my R5 is exposure compensation only I can go to stops to the left and make it darker or two stops to the right to make it brighter depending on the bird or the bride to be. Two different worlds but the same settings. Now I just got a Canon R7 and the Canon R8. They only have two dedicated buttons instead of three. One is dedicated to shutter speed, and the second one is dedicated to exposure compensation. ISO 100 is the best ISO by far! But, you don't want to limit yourself being stuck on it all the time and not having good tracking, good autofocus, blurry pictures, and moments where you missed that priced shot. It's better to get the shot with a little bit of iso that you can clean up with Topaz or Lightroom then not have the shot at all. If you disagree, then you're not being professional, and you shouldn't consider yourself a professional because you're limiting yourself. Professionals are Pros because they don't put limitations on their selves. Thank you, Simon, for all the great videos. And everybody every village has its own idiot. And there's no shortages in the KZhead comment section. I used to post in photography groups, and there would always be people with negative comments. There's always that one person who knows everything. But when you go to their wall and look at their pictures, they're usually the most amateur picture of all, or they have no pictures. Just like a lot of people in the comments sections. They know everything , but they don't have a KZhead channel to show and explain. In the end, let them stay on ISO 100, and we can use manual with auto ISO and keep getting all the great shots. 😅😅😅😅😅... because at the end of the day, it's not our comments that speak for us it's our images!!

I've seen lots of opinions (on Reddit, mainly) from folks who can recite the textbook theory behind photography and videography principles, but who clearly don't actually exercise those theories in real-world situations, and therefore don't fully understand the limitations (or when to bend or break the rules). Thank you for sharing!

    • No, 'native ISO' does not mean 'unity gain'. In truth, different cameras have different amounts of gain at base ISO, and unless you know your camera internals in detail, you won't ever know what that is. The 'similarity' between photography and audio engineering is misleading, because in audio the input and output are the same kind of thing, sound pressure waves, so you can talk about 'gain' if you want. In photography the input is light energy but the output is a perceptual recipe describing how a human should see it, regardless of the amount of light. You can't have 'gain' between completely different kinds of stimulus.

  • Great video. Two things I want to add: 1. It's important to differentiate between full frame cameras and crop sensor cameras. With full frame sensors, you can go on much higher ISO without ruining the shot. Especially with the new denoise AIs, they can't reliably handle for instance ISO 6400 on a micro four-thirds sensor. Textures will look very weird. 2. When turning up ISO, as mentioned in the video, you sacrifice your full well capacity. For instance, look up the astro camera asi 294 mc pro color. You will find some charts on this one for sure (as I am looking at one from the web right now) and you can see that at ISO (or gain) 120, the camera operates at a full well capacity of only 11k down from 64k (!). That means you lose an insane amount of information (82%) your sensor is then able to collect. It's true that you should not let ISO keep you from shooting (as there are fairly noisy images that won prices), but you should be mindful about what you do when increasing ISO. Turn ISO down first thing if you can, and turn it up at last if you need.

    • I often use higher ISOs on my OM1. I have not done any tests, but the general idea applies to MFT. Perhaps there is one stop of difference, but the physical size of the sensor is just one factor. I find that learning how to use the camera is almost as important as learning photography. :D

  • "High ISO is revealing that it was noisy, not creating the noise." A subtle nuance, and one that I was not aware of! I am enjoying my time at SDU (Simon d'Entremont University). I am amazed at the depth of knowledge you are sharing. It really is tantamount to attending college level courses in photgraphy. I think it woud be a blast to be a tag-along on one of your shoots to observe the process(es), the patience, compositional aspects, the sheer volume of shots... and the patience it takes to get the images you do!

  • One of my favorite photos that I've taken is technically a garbage shot, but the scene is just a perfect representation of that morning. I was still very early in to learning to use the camera, and really had no idea what I was doing, which lead to a horribly noisy photo...but just the simple fact that I had taken the shot made me happy. I still keep a print of that shot to remind me of two things....try harder to take a good photo, but if that fails, just go for it anyways.

  • I have my camera configured with 3 user profiles - each is aperture priority, auto-iso, but the minimum shutter speed is different (and for one the bitdepth is too to get higher framerate). This way, I have a main profile with 1/1000 minimum shutter speed for 90% of my wildlife work, and a 1/125 profile for when the subject is static and I am willing to go with a lower noise. Leaning to accept noise was an important step in my photography journey and it saddens me how much shots I 'lost' because I was too worried about going away from ISO100, and as a result ended up with a blurry photo because of a moving subject. Especially with the capability of AI noise removal in tools like lightroom and Topaz Labs makes me not worry at all even shooting at ISO25600. Also, Simon, are you by any chance an electrical engineer by trade? There is something about the way that you use gain, SNR, shot noise etc... that only us engineers tend to have.

At least the software of my Canon 5D IV has the strategy of lowest IOS possible programmed into it. On P mode it will first turn the aperture down to the lowest limit, then the exposure time to very slow, before it raises the ISO. Same on Av mode. Definitely the wrong programming for moving subjects.
