"Auto ISO with D3100"



Not understanding the operation of this feature. I have it set on auto iso yet when I frame a scene in dim light the shutter speeds are reading way down (1/30, 1/15, 1/8, etc). The scenes are no that dim so if the ISO were set up to 800 or 1600 the shutter should be higher. I thought the whole idea of auto iso was to bump the iso when lighting got too low to maintain decent shutter/aperture settings. Am I missing something?

Hi Bill,

Welcome to Nikonians!
In the camera menu under ISO Sensitivity Settings > Auto ISO >
What do you have the Maximum Sensitivity set to?
What do you have the Minimum Shutter Speed set at?
If you set the minimum shutter speed to 1/60th the camera will increase the ISO setting up to the "Maximum Sensitivity" that you have set in the menu. The shutter speed will get slower only after the maximum ISO has been reached.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Thanks Marty

but I have the minimum shutter set to 1/60 and the max iso to 3200. I set these the other day but i forgot how I did it. now when I go to that menu the min shutter and max iso lines are grayed out, I can't change them. very confusing.

Hi Bill,

You probably have the ISO set in Manual mode.
That would explain the grayed out settings.
In the ISO Sensitivity menu does it indicate:
ISO sensitivity.........XXX

Auto ISO sensitivity....OFF
Grayed out below

Scroll down and highlight:
Auto ISO sensitivity....OFF
and switch it to ON
This will turn on Auto ISO.
See page: 132 in the D3100 Users Manual
Good Luck and Enjoy your Nikons!

Best Regards,
Marty

Got it. Thanks Marty. I'm sure I'll have more questions.
