Up to six pages now. Will we get ten?
I'm the OP and was curious on topic and most post , except for the troll master USER ID and yours, were very informative. I just never shot a situation that required it but now I'll look for it and use it based on knowledge gained here.
I have no clue why people insist on trolling and post snarky comments post here.
I learned a lot and welcome different points of views on this topic.
Thanks to all that helped and to USER ID JUST LOOK UP his posting history all snarky rude and same child like pic over and over to see my point.

Posts like this are how we clutter the thread. Full auto and the amount of post processing are not related. But getting the wrong settings can lead to the need for lots of processing to fix it up.
Don't worry too much - most of the thread is cluttered with rubbish anyway. Enjoy it for what it is.

Na, don't care what settings you want to use, it's your choice. I use auto ISO to get the shutter speed that I need for the picture I'm taking ... usually, things are happening too fast to be able to stop and change the ISO. Do what you need to do ...

I see people using auto ISO and wondering WHY?
I shot as low as I can 100 to 200 and sometimes 400. I realize it's only one third of the triangle and modern sensors can do a lot more. Most cameras have limit sensors for high and low but curious if there is a reason for auto that I'm missing
I use Canon rebels crop sensor 77D and T7i. I'm happy with my cameras and can't justify expense of upgrading, too many other hobbies.

If one wants a particular ƒ-stop and shutter speed, set auto ISO (with a minimum shutter speed set) and the camera will adjust the exposure as required by selecting the needed ISO (within its limits). Each camera may have its own set of rules for what auto ISO can and cannot do for each particular Mode set, like Aperture Priority, Manual and Shutter and Program modes.
I use Aperture priority with auto ISO 99.9 % of the time. I vary my minimum shutter speed depending on what I am shooting. Macro usually means low shutter speeds as I am using a tripod. Birds in flight means a fast shutter speed like 1/1000 or 1/2000. And I vary the aperture as needed to control background and depth of field and what light is available.

Does any camera allow or give the option in auto to set a range of ISO? I see a possible advantage to limit noise.
Yes they do in the Menu settings. You set the upper limit.

With today's modern sensors the ISO range is expanded tremendously w/o the noise of yesteryear. Canon told me 800 ISO is no problem now days

In my Nikon cameras, when I set Auto ISO, I set the minimum shutter speed. I also set the ISO range I want at the same time. Done thru photo Shooting Menu.

If I use a Nikon flash, I NEVER use Auto ISO.

Actually I found when used with a Nikon flash it picks ISO400 and it works quite well.

I use manual with auto ISO almost 100% of the time. With modern cameras, ISO is my least important setting. I use EC to adjust for backlit or other tricky light. For me, the wrong shutter or aperture can ruin a photo. I can work with some fairly high ISO if shutter and aperture is where I want or need it. YMMV.

I don't like Auto ISO. I was using an old (2007) Canon SD800, and I couldn't get it out of Auto ISO. Looking in the manual, I found that I have to switch it to Manual. Then I can select 1600, 80, or several in between.
Of course, if you have a high shutter speed and a small aperture, the camera will want a high ISO. Then you have to process out the grain/noise.

after hearing a podcast years ago i tried auto ISO. the results were terrible; my nikon picked ISO 1600 for most shots.
i shoot manual and most of the time ISO 64.

I hope your ‘Nikon’ wasn’t a D500 - they are reputed to handle higher ISO values well.

If I am NOT shooting birds on water or birds against sky I will use manual/auto ISO instead of fully manual.Jun 5, 2023 11:12:56 #

Auto-ISO is an auto-exposure mode. You can set boundaries for high and low ISO. It can be used in conjunction with other auto-exposure modes, such as aperture priority.
And now I ask you, could there be any conditions, scenes, events, where using auto exposure modes make sense? if yes, what are they?

One example where the use of auto ISO can be useful - street photography. In this genre many photographers prefer to use zone focusing and therefore look to maintain a specific shooting aperture (perhaps f/5.6, f/8 or f/11 depending on their specific format) to provide enough depth of field. At the same time they may want to maintain a known shutter speed for the purpose of freezing movement in the scenes they are confronted with (perhaps 1/250 or 1/500th second.) In such case they could, of course, adjust ISO manually as lighting conditions fluctuate - but taking time to do do might result in lost captures - so using auto ISO solves that issue for them.

Another excellent example, thank you. I like street photography but I usually have time to adjust the exposure triangle but I'll use that tip to expand my range
