From my experience, the camera doesn't increase ISO until either the aperture or the shutter speed have been adjusted as much as possible. My Nikons let me set an upper limit for ISO. I forget what setting I chose, but I should probably increase it.

Yes, I saw all of the "debunkings."

Everyone's hair is on fire in the comments section here:

But here is a question: why should any of us care? why are there "sides" about this? Clearly the same ISO setting in one camera is quite different than the same ISO setting in an other camera. Ergo, it cannot be a standard, can it?

For some real solid information on Auto ISO please look at Backcountrygallery.com. From my experience there are a lot of folks that do not understand on how to set Auto ISO correctly. Steve Perry will show you how to do it. I helped a fellow 2 weeks ago. He had the upper limit on ISO set at 51,200. Way too high. So I helped him reset it and told him if that didn't work to just turn Auto ISO off. I shoot a D810 and D800 so I set my high ISO limit to 1250. My years of experience with D3, D600, D800 and D810 I've found that full frame likes 1250 ISO

Jerry - when my D5300 was brand new, and w/o my having made ANY settings, it chose an ISO of 10,000 - on a bright sunny day! … It was an extraordinarily good photo, however, w/o even a HINT of noise!!!

So what do these bright engineers know - we don't? …

THAT's the issue … not WHAT numbers we should impose, to rein in AUTO ISO ….

What was the "minimum" shutter speed set at when you set the camera to auto ISO? It seems strange that the camera in aperture priority would choose 1/4000sec when the aperture was stopped all the way down, and then raise the ISO to an extreme number.

You did something wrong Chris. You must set f/22 and 1/8000 shutter speed.

Good, tip, Larry … but ALL of MY DSLRs are APS-C … and the one in question - a D5300 - chose 10,000 ISO!

It seems to me - we, as photographers, should NOT try and impose upper limits on AUTO ISO, and let the cameras make those decisions for us, as, apparently - the engineers who designed them, know better than us!

It was on AP, Bill … with AUTO ISO (no limit set - at the time!)

I really encourage you to watch the video that Steve Perry has on Auto ISO. It applies to both full frame and crop sensor. You need to check your D5300 for Auto ISO. Nikon might not have put it on such a basic camera, but I think it might have it. If your camera was using 10,000 ISO then it was set there by someone either at the camera store or someone else. Watching Steve's vid on auto ISO will clear up all the mystery around ISO.

Not I, Bebu … I set the camera at f22 on AP … the rest was all left up to the camera ….

Not really so BASIC, Larry … in many ways, that camera is a better design than my supposed Nikon best - the D7100 … it has the fully-articulating screen, AND a built-in GPS … you don't have things like that on Nikon's entry-level cameras - the 3000 series. … It was on AUTO ISO - when someone asked me to post some of the pics I considered "great" - I went straight to the pool for THAT camera, rather than the D7100, or the later 5000 series I have - the D5500 … and picked four - all taken at different times, and different places - and they ALL employed outrageously high ISOs on clear sunny days. Had ME scratching my head, let me tell you!!! ….

I always use auto ISO when in aperture priority on my current bodies as it does what I would do. That is - it sets the shutter speed to 1/focal length (in 35mm fov terms) if possible.
I do set an upper limit, the valua depending on what I lighting conditions I am shooting in.

One thing I cannot understand is why not have a look around the viewfinder, or check the top display, and check what the camera is doing, especially if you are shooting 'scapes where you usually have some time to work. If you see the ISO going to stratospheric levels then do something about it.

Steve's video is excellent at explaining how to set the camera to use auto ISO in a specific and limited set of circumstances.

The video does not "clear up all the mystery around ISO" nor does he attempt or claim to do that.

Take control, the engineers may not know what we are trying to achieve with a particular scene.

If automation doesn't work for you then don't use it.

camera engineers don't know how much noise is acceptable to any particular photographer. One of the first things I do when I get a new camera is do ISO tests under various kinds of lighting so I will know for my own taste what I should set max ISO at. And you still have to use common sense to not use shutter speeds unnecessarily high or apertures unnecessarily small when using Auto ISO.
