  4. Are you using Auto ISO setting on your camera?

Are you using Auto ISO setting on your camera?

I'm playing around with my cameras settings and reminded about Auto ISO.  

Will you use this setting at all?

The only time I'm not using it is in studio sessions
because all conditions are controlled and the reac-
ion time is rarely critical.
Light is free… capturing it is not!

I use Auto ISO a lot especially with wildlife and birds. I set my camera on manual. I set the shutter speed so I won't get blur from movement and I set aperture for the DOF I want. I let the camera worry about ISO. It's when I am in a controlled or semi-controlled environment that I choose all three. If it's a landscape I make sure to pick the optimum ISO for clean images.

I set my iso to its native setting when I am using a flash and want absolutely no noise. ISO tends to be more evident in macro than other areas of photography. 

Its on auto for for pretty much everything else, and, if the conditions permit, I use it with a flash too.

When I'm using Aperture Priority I am.  When in Manual Mode, no I'm not.

I'm on and off with Auto ISO, I like having control.  I know it will always fish around for lowest ISO value to use for the shot.  Eh, that's likely my like to have control side of me talking.

I never use it.  It tends to choose higher ISO's than I need for the situation and that introduces avoidable noise.  I set ISO manually for the given subject or lighting conditions.

I'm curious. How does it choose a higher ISO than you need? It chooses the ISO to make the other settings you have set work. If you want it to choose a lower ISO, you need to change either your shutter speed or your aperture. I have heard others say it picks a higher ISO than needed and I would like to know how that happens.

G'day Nathan

Generally speaking, I use Auto-ISO with an 800-ISO max for 90% of the time ... being that most of my pics are landscapes and general everyday stuff. I will go for a set ISO in other locations, esp when I am using "S or "M" modes

I take note of the ISO in the EVF as I am shooting and regularly see 100 - 160 - 200 sort of numbers, even though it's set to 800-max

Hope this helps

Depends on the camera brand. With my Olympus I use it a lot. Not quite so much with my Canon.

Yes, except when in manual mode.  Well let me make a correction.  That and about 70% of the time in Aperture priority mode.

Hardly ever, I don’t like not having control and the semi randomness it sets the white balance.

I don't know why it happens.  Obviously it is built into the sofware that controls the camera.  The base ISO for my cameras is 200.  I set that manually so I don't have to even think about digital noise.  200 work for a large percentage of what I shoot.  If I need more I will increase it manually but never beyond 800.  In very low lighting I will use a tripod way before I use extreme ISO.

In the film days we were working with ISO numbers from 64 to 400 for the most part.  Millions of great images were produced.  While the camera technology has changed, the requirements for good photography have not.

Maybe I'm nuts, but I would think the ISO value would be based on the camera's meter. And different modes could produce different results, right?

I find that, on my D750, the auto mode tends to choose values that are "hot" under challeging conditions (e.g. harsh mid-day light). I don't like risking blown highlights, so I'll use auto mode to see what the meter thinks, then set a specific value and validate it. After that I make changes across the board, as required.

Under less challenging lighting, I can often trust Auto mode. But I still chimp.
