As you implied, ISO (sensor gain) really has nothing to do with exposure (the amount of light per unit area reaching the surface of an electronic image sensor, as determined by shutter speed, lens aperture, and scene luminance). Perhaps, a follow up talk on modifying the amount of light would be useful - increase luminance with flash, decrease luminance with ND filters etc. That should actually be the third side of the "exposure" triangle!

Nice refresher course and thanks for clearing out how to pronounce iso! Glad you mentioned the relevance of digital noise especially since so many times an image creator will share it in a social media platform that to begin with it is not too big in size. I remember when megapixels were the big discussion and how many commercial Photographers gravitated towards cameras that the file out of camera was close to the size of a billboard. Thank you David Bergman for all the content you share with us all in the ADORAMA channel!

Thanks David. Love your clear explanation. As a street photographer, I don't always have the luxury of shooting in full manual so I normally fix the shutter speed and aperture and let the camera decides the ISO. Thankfully, my camera allows me to set the maximum ISO so that images won't get too noisy. I hope this tip helps other photographers ;)

The only way to get better is to go cold turkey and don't rely on the camera. It takes some time, but exposure will become second nature.

I use FV mode and auto ISO for BIF shooting, where the exposure can change quickly and dramatically between shots. I use exposure compensation to change on shots that may overexposure or underexpose depending on the subject I'm shooting (a dark bird versus a light bird).

Well done on explaining what ISO is, what it is not, and how to pronounce it. Now, do a video on why it is not shutter speed. It is actually exposure time.

David, great amount of detail in a compact video. The one I still struggle with a bit is the Dual Native ISO. I think your R5 is dual at ISO 100 and 400, so shots at 400 look cleaner than 320. OK, off to go cry in a corner as I seem to recall my different generations of Sony bodies have different dual native ranges.

I agree. While it is best to use the lowest ISO possible, many photographers get hung up too much on noise. Topaz noise and other ai noise software seems to be able to reduce noise in photos by about two stops with no noticeable reduction in image quality. Between software and sensor advancement I have no problem shooting at ISO 6400 all day and going much higher when I feel the situation deems it. Software is getting better all of the time, but a blurry photo will be blurry forever. Personally I prefer using the auto ISO setting going as high as I am comfortable with, letting my camera set the exposure via the ISO, and manually setting the aperture and shutter speed, the creative decision for 95% of my photos, but that is me.

I´ve tried Topaz Sharpen AI and I absolutely love it! Noise? Gone! Slightly motion blurred images? Fixed! I tried it first on an 60 year old picture from my mother in law, blurry, slightly oof and it fixed it, so that it looks like it was shot with a modern camera two days ago.

The ISO prononciation had me in stitches. Its the same in the wine industry standard tasting glasses "eyesso" vs "I.S.O"! Just to confirm for that trade the correct pronounciation is indeed: ""eyesso glasses". That's settled then!

Great video!! I have to point out that at 3:42, if it comes from the Greek, the pronunciation is not /ˈaɪsoʊ/ but /ˈiso/. It starts with the "ee" sound in "sheep" and ends with a pure "O" sound.

There is more to ISO than meets the eye. I’ve only ever seen one explanation that matched by experience. Sadly, I don’t recall the details off the top of my head. But, I’ve shot images in the shadows at 4000 ISO with zero noise. And I’ve also shot images in well light areas at 400 ISO that was loaded with noise.

Thanks for the mention, Dave, and DOUBLE thanks for clearing up the pronunciation of ISO! I was today years old when I learned that. (yes, I always said it as an acronym...that apparently I must have made up) This video is yet another reason why I constantly refer friends that have just taken up photography to you. There are no better tutorials for clarity and concise explanations of the dreaded exposure triangle than yours. I'm curious now- how would a series (or at least a video or two) on "Your First Creative Image" work? i.e. first long exposure, or first night photo, or first panning photo, etc. In my discussions with many that are new to photography, they literally fear getting away from Auto mode, yet really want to take pictures that they have seen (that ARE easy to do). Just a thought. And as usual...Kudos!

I am a self admitted pixel/noise peeper on my editing monitor. I may have a little PTSD from older digital cameras. I really didn't like going over ISO400 and if I had to push it ISO800... ISO1600 felt like I was putting the photos through a meat grinder. Haha. Even today with my 5Div I try to keep in ISO400 and under if at all possible. Even though I have shot higher with it and have been impressed with it's performance... my brain tries everything to keep it as low as possible. #pixelpeeper #busted :)

When I bought my 6D a couple years ago, I'd graduated to high ISO performance: 12800 for simple snapshots is acceptable. But I fell into the Auto ISO trap and saw images within a series exposed differently. Worse, it took a long time to realize why, because by then I'd stopped paying any attention to ISO. It's humbling to so easily forget about the exposure triangle like that.

I'm not a mechanical engineer, but I don't think it does. Long exposures, however, do cause enough heat to generate noise. I did a video about it here: kzitem.info/news/bejne/sHmCyp2VfGhlYHo

thank you Mr Bergman as always great topic, it would be a stretch to call my self a professional photographer, all winter Long shot pictures at this church where the lights resembled those of a "Band stage" I have a sony a74 mostly shooting at 2.8 iso 1600 and from 60 to 125 on my ss, my question is why is it that at this simmingly low iso my images are way too noisy, and also can you explain dual ISO, thank you. is it my camera? or should I have gone to the dark side and invested on Canon or Nikon instead.

I don't know too much about that particular camera. It could be that, but it also could be your raw conversions. Maybe you have them being over-sharpened or some other setting that's adding unwanted noise.

So, once you max out the shutter speed and aperture, if the image isnt exposed properly, you can increase the ISO to get more light, avoiding too much, otherwise you risk digital noise. OK, I got that. But, what if you want to shoot night scenes, i.e. landscapes, will you get noise if the correct exposure was 30s, f1.2, and 256k ISO ? The question is, even if the ISO is very high, but its correct for the scene, taking in to account the other settings, and the camera is not filling in the pixel gaps, because the sensor is getting the image, will you get noise, even at a high ISO ?

I don't think this is a good explanation of what changing the ISO does. Yes, it will of course as you stated change the sensor boost. It is however simply not true that, as you state at the 2:00 minute mark, that changing the ISO does not physically change anything. It most certainly does. That is the main reason the variable ISO setting exists! When we change the ISO we change the amount of light that is allowed to hit the sensor by in turn increasing or decreasing either the aperture or the shutter speed or both. Anyone with a digital camera can verify this by simply setting their camera to aperture priority and the ISO to its lowest setting say 100. Point it at any subject and make a note of the indicated shutter speed . Now change the ISO to 400 and you will find the shutter speed will change to 1/4 of the previous setting.
