Auto ISO
Jun 4, 2023 12:38:30 #
Do you set all 3 of the triangle variables manually? I don't, I allow the camera to set the exposure. Which one varies with the situation. Sometimes I want to control stop action or to blur moving water. In those cases I set the shutter speed, but what about the other 2? Well, if depth of field is also a concern, I will also set the aperture. This leaves only Auto ISO so the camera can set exposure.

I use Aperture Priority mode with Auto ISO and full Manual. Never use Manual with Auto ISO. I use these 2 modes about 50/50.

I use full manual if there is time to determine and set the best settings. If changing conditions or lighting don't allow that time, I will use aperture or shutter priority depending on which is most important, or I will set aperture and shutter speed with Auto ISO (with a limit). I only want the camera to determine one setting and I control the others.

I was looking for general information and if I was missing something. I don't need a snarky post like yours.
What was point of your rude post

I’m mostly in Manual Exposure and almost always Manual ISO. This allows me to determine what adjustments to make to each of the three legs of the triangle to achieve the exposure I want.
There is not one way that is right or the best. Different strokes for different folks.

Amazing how that works, eh?

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?

Longshadow gave a good example in his post when auto ISO is advantageous.

Can you deliberately over expose or under expose in Auto ISO?

That seems to depend on what camera you are using. My cameras allow me to apply Exposure Compensation in all exposure modes. Some cameras apparently have limitations.

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.

I like you prefer to set my ISO to 100 or 200, depending on lighting conditions. I can understand why some prefer auto ISO but am constantly surprised at the number of people who claim to shot manually but then say that they have camera set to auto ISO. It has always been my understanding that shooting manually means the photographer selects the aperture, the shutter speed and the ISO.

Yes you simply use the exposure compensation but I never do that. I would switch to full manual.

Why give yourself an added distraction when you can get the camera to do it for you?

I hate the EC. I never use it. You let the camera does it for you but you said, you're wrong camera, you have to increase the exposure a bit. When I let it does the job I let it does the job otherwise I do it. Much simpler. I don't want to tell you do the cooking for me but by the way add more salt and less sugar.
Manual everything is no distraction. I enjoy manual focus, manual exposure settings.

That's for all the helpful info. I know the exposure triangle and some of the examples were very helpful suggestions, like the cover bridge.
New cameras can use higher ISO then ever before
To me ill use up 800 for things but try to keep it 200/400. Bright days 100.

Thank you Larry, but then what does EC change?
