Use or don’t use auto ISO
Jun 12, 2018 06:52:53 #
I usually choose the fstop and shutter speed and let the camera choose the ISO. If the ISO the camera chooses is too high in my opinion then I simply change one or both of the other parameters to suit my needs.

I use auto ISO for Birds in Flight one less thing to control in the heat of the moment. I have a Nikon D3 I set the high limit to 3200 and use a Sigma 500 f4.5 prime lens most of the time. In early morning light changes so fast and action happens so fast if I had to adjust my camera all the time I would miss lots of action. Auto ISO give me the option to set A and S to the conditions I'm shooting with little time loss.

This is a matter of control and I want to be in control with my camera.
My Auto ISO is always off.

I've never used auto ISO. As of late Jan. 2010, I've not used auto anything.

About the only time I do NOT use auto ISO is when shooting with flash.
When depth of field and shutter speed are critical, one example, action in changing light, its unbeatable. Modern cameras can react much faster than humans. Aside from basic functions, its the most important feature on a camera. If you are not using it...you are missing out big time.

I set shutter speed and aperture based on my subject and what I want the result to look like. I set ISO manually if conditions call for it. If you're getting the look you want and aren't frustrated by incorrect exposure, why change?

As someone who photographs wildlife it's auto ISO all the time for me.

I almost NEVER use Auto ISO. I generally keep my ISO set to 100 unless it is going to cause too low of a shutter speed for the widest aperture. I will usually either use Manual, or Aperture and if necessary edge my ISO up to the lowest ISO for my needed shutter and aperture. Also keep in mind that a wide open aperture will NOT always fit your needs.. I often set aperture to f/8 or higher (meaning smaller opening or slowest speed consistent with the photo. Remember that if you are shooting race cars in shadows or anything less than bright sun, you may have to open the aperture as you want to keep your shutter speed high. All photography is a balance between shutter speed, aperture, and ISO. (Exposure Triangle). If you learn to use the triangle, then your photography will be much easier. Typically, Auto Exposure will give you a wide open aperture with a balance between shutter speed and ISO.

Based on a variety of posts here... in the past... I with my D7100 on Program... shooting RAW with auto ISO and auto white balance virtually all the time. I find I get (IMHO) excellent pics (composition notwithstanding) whether inside or outside with no need to make changes.
Here are two shots I just took to help make that point... one inside and one outside (on a dreary day). Both are RAW and no processing has been done... SOOC.
It works for me.

For static subjects and lighting conditions I control the ISO when shooting moving objects birds etc. I allow the camera to adjust as needed To compensate for the changing lighting conditions.

Hey, you mean you don't get copies of the images afterward?! Mine are framed and hanging on my wall! But they would only give me relatively low res JPEGs so I have not had them blown up to mural size.

I use Auto ISO most of the time unless I am shooting JPEG only and won't have a chance to recover in post.

I use auto iso when shooting birds in flight. Set shutter(1000+) and aperture (sweet spot of lens). If birds move from dark to light, iso compensates.

When on a tripod for landscape photography, I use aperture priority with a small aperture and with ISO set to its base value.
When doing street photography, sports, or wildlife, I use manual mode with auto ISO, adjusting aperture and shutter speed depending on the subject's actual or potential motion and how much depth of field I want.

I occasionally use Auto ISO with Manual (which makes M another auto exposure mode). But only when I want a specific shutter speed AND aperture, need to accommodate variable lighting conditions, and am not too concerned about what ISO is used. I'm more inclined to use it in "good light", when the ISO is unlikely to be pushed too high.
But that's rare and most of the time I just set ISO myself.
I NEVER use Auto ISO with any of the other auto exposure modes (Av/A, Tv/S or P). That essentially is a double auto mode that serves no purpose that I can think of, might even make for unpredictable results.
And I NEVER use full "Auto" or "Scene Modes".... those automate much more than just auto exposure and prevent me from making a lot of other important camera settings (auto focus, white balance, Exposure Compensation, etc.). The won't even let me save RAW files, which is what I normally want.
I shoot all sorts of things, but the majority is sports/action.
