Is this in Porthgain Wales?

[@snitzoid]

There are several reasons I often shoot at ISO 100(especially for landscape situations in difficult light). 1. More dynamic range. Most modern cameras gain 2-3 stops vs ISO 800. 2. Camera shake even hand held is a minor issue, easily handled. Modern mirrorless cameras now sport up to 6-7 stops of on board image stabilization. Shooting at shutter speeds of 1/focal length usually works.

[@abrogard142]

hell of a lot of us don't have modern mirrorless cameras. I think this vid has mass appeal/application when you take that into consideration. I know my (poor) camera skills/shots improved from when I learned not to be frightened of upping the ISO.

[@najadadavis]

I thought it was no less than 1/double your focal length.

[@Xirpzy]

Anything below 800 iso is a non issue. Ive gotten amazing shots with 3200 iso. My photography improved once I started to use higher iso. Motion blur and wrong aperture are much more damaging than high iso. Especially on modern cameras. Changes to those two impact how the image looks completely. Once I got comfortable shooting at iso ~800 I could use shorter exposures and smaller apertures which opened up my creativity alot. Now I set aperture, shutter, iso in that order rather than being stuck on max aperture and lowest iso. But thats just my experience. As with any kind of art it comes down to preference. Dont be afraid to explore the options and learn what you prefer. Took a few thousand photos for me to dial in what I like in what situations. My advice is to just get out there and try stuff.

[@fredericveilleux5590]

@@najadadavis It's a rule of thumb that dates back to the film era. But yeah with high resolution (36mp and up), you're quite right. If I'm moving while shooting I'll even try and keep it 1/triple focal length if it's at all possible

[@yuvtube1]

All of those things about shooting low ISO and shooting high shutter speeds are true if you have a fast, large aperture lens. Most beginers don't have those lenses. This is true even for low light photography and true for Videography with ND filters. You can truly apply these techniques only after you get a right gear.

[@nerdynautilus5373]

Just don’t forget that ISO affects more than just noise - high ISO reduces dynamic range and color accuracy. Sometimes the trade off is worth it such as when freezing fast motion or when shooting at narrow apertures but most of the time you’ll get better results just using a tripod

[@edgarasjocius5175]

Thank you!

[@BobN54]

"Just don’t forget that ISO affects more than just noise - high ISO reduces dynamic range and color accuracy." Not really. What reduces those is lowering your exposure, which you'll do when you raise the ISO, if you centre the meter. The effect on noise is the reverse of what people think. If you keep the exposure the same and raise the ISO you'll often reduce the noise, albeit slightly.

[@orphanuprising]

@@BobN54 Kinda depends on the sensor and ISO invariance/variance too. Sometimes you'll get a lower quality image by shooting at low ISO and raising in post, than if you just raised the ISO in the first place.

[@KiR_3d]

The new cameras usually allows to use really low ISOs although their natural ISO is higher (like 640 in Fuji X-T3 for example). But it allows only with ONE IMPORTANT restriction: you get a lower dynamic range! ISO640 can have 400DR but ISO80-100 can have only 100%DR.

[@BobN54]

@@orphanuprising Actually, not the sensor but the electronic processing after the sensor, dual-conversion gain, all kinds of stuff. The real point is that it's not 'ISO' that causes noise, it's the lowering of exposure that you get as a result of the ISO control changing the exposure at which the meter centres. It's all related to knowing what 'exposure' means, and that you can't change it in post ;-)

[@markr3926]

Before increasing ISO to obtain a briefer shutter time, take the 6 stop filter off! maybe put a three stop filter on. Or just a polariser, or polariser and 3 stop. Use a variable ND. Just a thought.

[@edgarasjocius5175]

Hahaha love this comment 😂 So true

[@ontheruntonowhere]

So now you need a 6-stop filter, a 3-stop filter, a polarizer and a variable ND? Not everyone is blessed with such choices in their gear collection. Besides, working your ISO is nothing to be afraid of and a skill you should learn.

[@markr3926]

@@ontheruntonowhere I disagree, raising ISO should be the last compromise. There are some great tools out their for dealing with higher ISO but they often cost more than a filter 🤷🏻‍♂️ which anyone with a digital camera, tripod for long exposures, storage cards, a computer to process, and software to process can probably afford an entry filter. And no filter is required at all to extend a shutter speed a few stops if your starting point is 800 iso, just dial down to the cameras base ISO 🤷🏻‍♂️ Besides the chap in the video has at least three of the four filters referenced! and my reference to a Variable ND was a budget option in place of the 6stop and 10 stop ND’s 🤷🏻‍♂️ The learning is yours. Why give yourself the work of dealing with noise when a bit of education negates the need in a case such as this 🤷🏻‍♂️. Why introduce a problem if it can be avoided? When there is no option yes of course thats the time to use those skills in post. But having the skill and the software to deal with noise in post is not a reason to introduce and avoidable problem. The point in my original comment is bang on correct.

I was looking for a comment like yours. ISO doesn't matter that much nowadays with mirrorless around, but that is not true for older cameras. I own a D750 and going over 2000 is risky. Lighting is the key and sometime you gotta work for it. This video is to be taken with a grain of salt as this only apply to modern cameras in my experience.

[@LatoremRisus]

I'm new to this field and I instantly saw what you all saw. New equipment you can worry less about ISO. However anything not of fairly recent quality, you do want to worry about ISO. Also a good photographer will be able to play with all of your settings to get the clearest, best photograph. So just improve your knowledge and skills for capturing that perfect photo. Don't settle though and just say "you can fix it in post" that's just simply lazy.

[@BrianKenyon]

ISO is just gain for RAW photos that are darker. Increasing it increases noise. The real limitation is F-Stop, shutter speed, and overall sensor size, pixel density, and pixel sensitivity.

[@PaulMcCannWebBuilder]

We have it so good these days. As someone who shot weddings, sports etc. with film, the talk of variable ISOs, affordable 8000th sec shutters and 1.2 lenses, and the ability to check your shots and adjust while still standing in front of the subject, would have been unthinkable back then. When the first digitals arrived, (primitive as they were) the fact that you could adjust ISO from shot to shot (without changing out a whole roll or carrying an extra body) was the biggest breakthrough.

[@eriztonoqarzwoss]

Just as big a breakthrough is that the cost of film was eliminated, as well as the inconvenience of having to reload it after every so many shots

Of the harbour shots, number 3 is fav for me....nice colour and the long exposure makes the water look great. Good advice too about the ISO settings.

[@georgedavall9449]

Indeed! 👍

[@TechnocratiK]

As someone who has done photography on a budget for a while now, I have some notes. For reference, I use an Olympus OM-D E-M10 Mk II. 1) If you're like me and only can afford an older camera, you won't have ISO invariance. Although colour noise is an issue with higher ISO, the bigger issue is how much you can change the exposure in post before you start to get artifacts (notably, a cell-shading-like effect in shadows or highlights). Ergo: 1a) If you're using a mirrorless and it has a feature to show you shadows and highlights live, turn this on. 1b) Lookup your camera sensor on DxOMark, specifically its dynamic range vs. ISO graph. The ISO where the curve crosses ~8 Ev is a good guess for the highest ISO you'll want to use. Some experimentation at high ISOs will be needed to nail down what you're comfortable with. 1c) As a rule of thumb, the higher the ISO you're using, the more you'll want to work to get the exposure right in camera. On my camera, ISO3200 is the highest I'm willing to go, so I know that if I'm shooting at, say, ISO1600, I have about 1 stop of exposure to work with in post. 2) Most cameras (even flagships) that support shooting below ISO200 do so with some support from the image processor. That is to say, there are diminishing returns in terms of noise reduction and dynamic range increase when lowering the ISO below 200. So going from ISO400 to ISO200 gets you a larger improvement than going from ISO200 to ISO100. 3) A variable ND filter is a nice tool for beginners... outside of landscape photography where corner-to-corner image quality matters more. It will let you control depth-of-field (via aperture) independently of shutter speed in brightly lit scenes, which can be useful if you want some motion blur in your photo. VNDs tend to create non-circular vignettes at their high end, though, so when going to buy one, consider its usable range to be one-to-two stops less than indicated. For example, I have an ND8-2000 (3 to 11 stops) which has a useful range of ND8-500 (3 to 9 stops).

[@pierrevilley6675]

I don't know if it is psychological or real, but my RAW files looked noticably punchier at 64 ISO than 100 on my D810, it doesn't really change anything on noise and sharpness, but the color depth was much better.

[@TechnocratiK]

@@pierrevilley6675 Yeah, I should clarify that ISO64 will be better than ISO100 (it wasn't psychological), it's just that the step up in quality from ISO100 to ISO64 is smaller than the improvement from ISO400 to ISO250.

[@COShea-iw6ii]

I prefer #1 on the harbor photo for the various colors and textures. I like seeing the water naturally.

[@realnicorobin8798]

define natural.... there is no "natural" photo, just like people say that iphone is "natural" yes i do prefer 1 too, its colors are more soothing but dont just pick a photo that seems to be "natural" every photo goes through a lot of processing so Dont just throw around the term "natural" say true to life instead

[@jspost3]

I’ll stick with natural, thanks. What I mean is, as the eye sees it, instead of a soft blur. You’re overthinking it and your comment comes off as condescending.

[@NimbusYoutube]

Yea not sure which I prefer between 1 and 2, but might be leaning towards 1 because of, like you said, the realistic depiction of the scene. Water in #1 is much better

[@5000Helme]

You mentioned the most important at the end. There are only two iso settings. Base and 2nd conversion gain. Keep you shutter speed where you need it to be and ignore the underexposure. Raise EV in post and pull back the highlights. A higher ISO setting leads to decreased dynamic range dramatically and this would be burnt into the raw file. If there is a low dynamic scene, well then you could raise the iso incamera and get the same result.

[@edgarasjocius5175]

Yes thank you!

[@simonbramwell4074]

Number 2 for me. There is nice detail in the sky, and the monochrome gives a timeless feel. The slow shutter speed in number 4 in this case to me makes the sea look like mud or wet sand rather than water.

[@ian_worth]

Thanks Simon 👍

[@jeremyevans9137]

I think this is great advice. I’d like to add a footnote for film photographers. ISO has two components: ASA and DIN. So ISO 100 is 100/21, where 21 is the logarithmic scale. You can’t quite change ISO as easily when shooting film, but you can use interchangeable backs for medium format and different slides for large format so that you have a range of film speeds available.

[@ian_worth]

I use an m43 camera and 100% agree with your first example around event shooting. I'll stick it in shutter priority so that it just never drops too slow, use the iso auto caps, and let the camera adjust those small details. I was in a dim lit wedding reception for a family member taking snapshots and the noise was completely usable at iso2000 and 2500. Better than worrying about motion blur and camera shake, that's for sure!

I love that i can set a range on my Fuji across three seperate preferances that are easy to apply on the go, i have 100-800, 800-3200 and 3200+++. Though typically i just set and forget at ISO 400 and go with the flow and enjoy the additional flexibility. Mostly using the auto ranges for night shooting where lighting can be extremely dynamic.

[@esainpereda3081]

I remember joint a class in community college( mind you this was after teaching myself and shooting for 3 years) and they would start off the students setting their iso at 400 for day conditions. We were not allowed to go lower . 400 was they allowed parameter. The idea was to mimic iso400 film but with digital. So I definitely agree with your message that when conditions change , bumping the iso can benefit the other settings tremendously.

[@dog4mike]

I've learned to become less obsessed with ISO in recent years. In a perfectly controlled studio environment, photographing for a client with specific needs, my rule is to shoot as low as possible and reproduce colour and detail as accurately as possible. For everything else, it's not a big concern, I let the scene and my emotions decide what is best. When creating for artistic purposes, things like perfect noise and perfect dynamic range don't matter so much. I am concerned with the story, creating an emotive piece, and that rarely requires a perfect reproduction of a scene. I often even add noise, reduce or alter colour, etc. Some photographers carry white cards and painstakingly obsess over histograms. Good for them. When it comes to creating art, I need people to feel an emotion or activate other senses. If someone is going to look at my photo and think "those flowers should be a different tint and there's too much noise for me to see the veins in that leaf", well, they are missing my point and are not my target audience. And that's OK.

Thanks for sharing this video with us. I see ISO as yet another tool of our arsenal of creative decisions. It really depends in the subject and the vision I have for the image I want to capture. I've literally found myself adding "grain" to moody monochrome landscapes before. It adds to the dramatic tone of a storm, for example. That said, for an image I want as clean as possible, I absolutely have no issue keeping my camera mounted on my tripod and walking around like that so that I can quickly set up a low-ISO tripod shot. Or even use the tripod as a monopod if I want to be quick. Either way, my priority is to have a vision for my shot, and then do what I need to do to get it, rather than work the other way round and let my outcomes depend on the limitations of a choice I made before I envisioned my photograph.

[@The-KP]

Good exposure is about good technique, which means correct shutter speed for the subject, aperture set to balance artistic and exposure needs, tripod or flash as required, and only then bump ISO if you run out of headroom on the other settings. If you're using auto ISO without knowing why, well you're a beginner and Einstein bless you! Experiment with other modes like shutter priority, aperture priority, and choose a fixed ISO when you do. Then you'll be forced to try various settings to get good exposure. Ultimately, learning to leverage the f-stop, shutter speed and ISO triangle comes with lots of practice. So get out there and shoot!

[@ian_worth]

Thanks buddy 👍

[@jonpaulpepen9470]

It's more a matter of sensor generation. Image-level noise/detail doesn't strongly depend on pixel count for a given sensor generation. For sensor size, when applying crop factor squared as an equivalence correction, the only difference, again within a sensor generation, is that larger sensors can go down to lower equivalence-corrected ISO settings, which has potential noise benefits if you can increase your subject illumination. I'm not really sure what you mean about long lens vs short lens. Camera shake maybe? Otherwise, focal length should be completely irrelevant to the ISO/noise discussion.

[@Eikenhorst]

7:47 why would you increase the ISO to get the desired shutter speed here? Instead of increasing the ISO, leave it at 100, set the aperture at F8 and the shutter speed to 1/3s and take the shot. It will be slightly underexposed but that is easy to correct in post (any noise you get from this are similar to raising the ISO)! You obtain a bit of highlight protection this way as well, handy for the foamy top of waves you might otherwise clip. Most cameras have dual gain sensors and are not ISO invariant. Raising ISO above that limit means you get less noise by raising ISO in camera than in post production. When you have an ISO invariant camera this doesn't make sense (although it is a bit hard to review on the spot when the result is almost pitch black!)

You are right, and its a very valid point regarding underexposing. The 2 end results would be virtually the same noise wise. I guess it comes down to wanting to get things as perfect as I can in camera, which is what I'm always looking to do. I'm always very mindful not to clip the histogram, so that wasn't a problem here. I don't think there's a right or wrong answer, I just like to shoot with intent as I find it more rewarding. 👍

Another good information video when i first started i used to set I.S.O at 100 0n landscape but now its set on auto for quite a lot the new Denoise in L.R is brill so for my wildlife its auto all the time

[@ian_worth]

Cheers Doug, Yeah, that denoise feature is pretty amazing 👍👍

[@jishin75]

Favourite photo, the two bw since the colors weren't such a thing in the shots. And the small white house adds a lot in monochrome. Nice video

[@forestchaput]

Great video Ian!

[@bonynge5]

The delightful Porthgain. Taken many a photo there during holidays.

I started photography using film when there was a huge difference between ISO when it came to graininess. ISO 100 vs ISO 400 or 800, huge difference. So now I hesitate to shoot with ISO above 100. But this video gives me something to think about.

[@gregor393]

Yes I had a BW background and a love of Ilford 400ASA film, because of its beautiful grey scale range. In digital I usually use 1600, to compensate for my elderly tremors, and there's no sign of graininess.

[@MikeGiovinazzo]

WOW - never heard of ISO invariance. Very cool concept and I found my Nikon 6II is ISO Invariant so a whole new set of techniques are now part of my tool kit. Many Thanks.

[@ian_worth]

Glad it was helpful! 👍

[@madmechanic7641]

Please bear in mind it matters to a major degree whether you're shooting on a newer cam or (like myself) an older dslr... And remember the newer these camera's get the quicker they get older!!! My old 5D3 still rocks though...

[@newfoundlandscenery3568]

Very instructive!Man that place looks exactly like Newfoundland. New subscribers here!Good luck!

[@ian_worth]

Awesome, thank you!

[@Roger_and_the_Goose]

I also use higher ISO for my B&W photography to add grain like a film photo

[@timscanlanphotography]

Hi Ian. Cracking video. Really well explained. ISO invariance is a gift, especially for us astrophotographers ! Thanks for sharing.

[@ChuihcguRydughx]

Usually I use filters to help my job, like kase or Nisi. It's helpful for me to adjust the light.

[@LordLauchlan]

Image number 4 for me simply because I prefer B&W photography with a slow shutter speed but I'm certainly not averse to colour photography. Like you, I often take multiple shots of the same scene at different settings to see which shots I prefer. Thanks for the content you produce and keep the good work Ian, I enjoy viewing your videos which not only educate me but provide inspiration too. 👍

[@paulcomptonpdphotography]

You defo make some of the best explained video out there. Tha ks

[@ian_worth]

Thanks Paul, that means a lot mate 👍👍

[@amybradley5821]

Thanks! I’m old school so always wanted the lowest ISO possible for print. I still feel icky at 400 but I’m going to try and let it go!

[@matthewdray83]

Not sure I agree with you 100%, I think your key message to understand how use your shutter speed to get the shot you want and the how ISO contributes to it. High ISO in low light or high dynamic range can add a lot of noise to the shadows. Especially for entry level cameras. The Key is to expose to the right to compensate, but in my experience a lower ISO and a Tripod give better results.

[@eriztonoqarzwoss]

Very good points. I have observed that most of the photography videos (tutorials) on youtube, assume that the people watching it have eight a full frame sensor, or APS-C sensor. There are bridge cameras with one-inch sensors that take stunning shots. So, the advice of bumping up your ISO settings to much higher levels won't necessarily work as well for these bridge cameras.

[@bwebmasta1]

A great video & excellent content, with detailed real use cases for varied ISO. I just subbed!

[@ian_worth]

Awesome, thank you! 👍👍

[@thephotoroad]

Great video, well explained and useful. Thanks!!

[@therockhour1386]

Immediate subscribe... thank you so much for sharing your experience. Im an audio/musician producer guy for a few decades now.... and I'm beginning to dabble in the visual realm. This conversation is so much like me describing mic/preamp/compressor/eq choice.... thank you!

[@ian_worth]

Thanks for the sub! Much appreciated 👍👍

[@Calkil64]

#3 is the one that caught my attention. 👍

[@AndyWoodger]

For me it's photo 1, the sky beautified the scene. The black and white are OK but I'd add more contrast so the darks are darker and the light lighter, although it doesn't need much change. I used to use film for my weddings, 1600iso film but set the camera at 800iso very punchy portraits.

[@daviddelaney363]

Quite insightful...Thank you!

[@hartgetzen7867]

Brilliant, Ian, as usual. Thank you!

[@MrShanePhoto]

ISO is just a completely different beast these days. When i started in photography shooting film and early DSLRs you only went above 500 in desperate circumstances. Now with a modern mirrorless full frame camera 3200+ is fine. And lightroom now has an insane AI noise reduction tool.

[@jamespitman3357]

ive shot video at 22500 iso on a canon c dslr at night with just a low powered street light for tv show - worked a wonder - no noticeable grain. ramping up iso if needed as u say no longer an issue in most cases

[@swaspc7618]

Nice show! my favourite is number 3!

[@markstambaugh3273]

1 and 2. I like the ripples in the ocean.

[@sashimifr]

Best poweruser hack to leverage automatisms/intelligence of the camera while retaining ability to manually set aperture and speed to your likings is to set the camera to manual (so you have control over both aperture and speed) while enabling auto-ISO (bonus if you can command the auto-ISO upper threshold). This is basically equivalent to a A+P priority mode

[@outlawph]

I kinda like wind noise, stil hear you clearly and it adds a bit of atmosphere

[@jeffslade1892]

When we have decent stabilisation, hand shake, camera shake, is not a thing but movement blur certainly is. May not think there is much movement blur in a landscape but a branch blowing about certainly is. I'm watching the tree waft about out of my window. Movement blur is a useable effect but that would look rather odd hand held for 2 seconds. Stabilisation can aid the AF at any shutter speed because the focus spot is not jiggling about. But don't go thinking stabilisation will let you use a lower ISO with a slower shutter to take a better photo, choose the shutter speed for the photo. What largely matters is what is happening in front of the lens and what you want to do with it.

[@granddadmark7639]

Harbour shot 4 for me BW longer exposure. Also the tip of under expose to preserve the highlights 👍

[@ian_worth]

Many thanks 👍😊
