The TRUTH Behind the ISO 100 MYTH that the PROS Know!

*🧩FREE PHOTO EDITING GUIDE*

In this week’s episode, we discuss the truth behind the ISO 100 myth that professional photographers know. When you're a beginner photographer, there's many techniques and "rules" you hear about. One of the most common misconceptions is the ISO 100 myth, which is the belief that one must always shoot at ISO 100 in order to create the best and cleanest possible photograph. In this video, I'll put this myth to the test to see if you can really even notice the difference between a high ISO image versus the same photograph taken at ISO 100. I guarantee you'll be surprised by the results. I hope you enjoy this week's video and as always thanks so much for watching! - Mark D.

🔥QUESTION: Do you say "EYE-SOH" or do you say "I.S.O."?

[markgoostree]

I am old. It was A.S.A. so I have always said it as I.S.O....I may be wrong but, does is really matter? I have the position that I want my ISO high enough that I can use a decent shutter speed as well as keeping my f-stop kind of in the middle. However, I am just a hobby photographer. No one sees my pictures... rarely are they shared. It is always a dance... trying to balance the triangle to get the picture we are looking for. That's the fun of photography!

My question why do the breezes wait until you want to take a photo before they start to

[markallemang]

Ok. Haven't finished the video. But you up close to the monitor looking with one eye up against it made my day. 😂

[jimtipton]

Cracked me up that Gavin Hardcastle figured out how to work his way into your video!

It's funny listening to you as a landscape photographer talking about going above ISO 100 when as mainly a bird shooter I routinely shoot at anywhere from 1000 - 3200!
Especially with todays brilliant noise reduction software and sensor tech those days of worrying too much are gone.
As the old saying goes "I'd much rather have a noisy sharp shot than and clean blurry one"

According to the International Organization for Standardization, the abbreviation for their name is ISO. On their website, they go on to explain that you should pronounce the abbreviation as a word: eye-soh and that the abbreviation and its pronunciation are based on the Greek root word for equal: isos.

Back in the before times, I remember taking my 100 foot rolls of ISO 400 film, loading it into a canister, and then shooting it at 1600 at sporting events because film with a decently high-enough ISO was too expensive for a high school student to afford. I'm just now getting back into photography (now mirrorless, I guess) and people refusing to shoot above 100 is one of the weirdest things I've ever heard.

[alanglassman]

Good argument for shooting in manual, and setting ISO to automatic, and letting it float. That is precisely how I shot airshows for years.

Came to find out about the ISO 100 myth I've heard absolutely no one talk about and you didn't disappoint. Great service. 👍

When I got back into photography with Pentax DSLR's, which were fairly good with pushing the ISO. Down the road I switched to Nikon, found that in most cases ISO6400 is as far as I like to push things - so now ISO is maybe the 4th or 5th thing I worry about. Composition, shutter speed, aperture etc. are much more important. So I really like the fact that I can set the other two and just not worry about the ISO. I'll let the camera choose what is needed - today's camera's really do a good job with noise (and we typically have editing tools to reduce noise).

If you want real noise - push Tri-X to 800 or 1600. LOL

Brilliant hoodie! Where did you get it from?

[jimstreeter]

So well put. Using the tools you have available to create the image and/or feeling about the subject in front of you. Thanks for sharing.

Hi Mark, great video. I typically say eye-soo. For the longest time I insisted on staying below ISO 400, and subsequently missed a lot of opportunities because I could not get the right settings. Now I set it to what it needs to be so that I get the shot. Maybe it is not portfolio worthy, but it is a reminder of what is possible if the conditions are different. When hand holding I often will set it to auto ISO. You mention IBIS, and how it has improved. My camera does not have IBIS, but if it did, could the lenses with image stabilization be used with IS turned on along side of the IBIS? I have never heard anyone talk about this. Thanks again.

Thank you so much for sharing your useful tips. Your landscape work is so beautiful. ❤❤❤

Eye-so

Great video! Just discovered your channel. Getting back into photography now that I'm retired.

Liked and subbed!

Hi Mark, freezing the video for a few seconds I quickly decided the one on the right was the one shot at ISO 100, from the superior clarity and resolution of the rock face to the lower right of the image. I have to say, though, I would not have put money on my assessment!!! Still, I was blown away when you said the image on the left was shot at 12, 800. The largest ISO I ever shot was at 2, 000 and that showed minimal grain, but the "trick"/technique I learnt is letting in enough light from what was a relatively stationary scene to illuminate the sensor, thus preventing excessive grain. It's not necessarily your high ISO that produces the grain but how you "marry" shutter speed with aperture value!. Enjoyed your video, as usual. Cheers, Frederick Jansohn

Camera, lenses, you need to know your equipment. I just shot a baptism in a church, no flash was allowed. Having a good lense with low aperture is a must. I don't like grainy pictures so I set my ISO range and I know well my lenses. Every situation is different. How good is your camera's stabilization system. Bottom line. Your technical knowledge is crucial. Great video. I always appreciate them.

[tjmanou]

I agree also especially considering the fact that there are very powerful softwares out these days to reduce noise even more without compromising the image quality.

[madelynrobinson]

Good thoughts and definitely going to practice increasing my Eye-S-Oh to increase the shutter to help with increased detail I’m wanting especially when handholding my camera - thanks 📸
