Took these pictures on same setting with my D7000. One through
view finder 1/25 at 5.6 came out 3600ISO. Took same shot
through Live view came out 5600 ISO. Was reading some advice on here for sharper pictures. Was told to use live view. Is this the
same as mirror up? I'm not a smart man.

viewfinder is mirror down
live view is mirror up.
all photos are made with mirror up.
liveview (mirror up) plus magnification is handy for critical manual focus.

The advantage of live view is the magnification available for focus adjusting.
Mirror up is a mode that allows for less camera shake due to the mirror slapping back and forth.

You didn't say what mode you were in.

Sounds like you were in auto something, that a different ISO was chosen by the camera in the 2nd image (the higher ISO image IS lighter).

your camera probably metered a slightly different spot

So the camera picked a different ISO in live view. As I guessed, you used auto something.

If you don't want the camera to do that, use manual for all settings.

on some cameras, the mirror drops out of liveview, makes a normal exposure routine and then returns to live view.
The mirror slap still gets you when that happens.

One more question. Were these hand held?

Yes, but why different Iso?

Old tigger explained it correctly.

"your camera probably metered a slightly different spot"

That slight difference will change your ISO if set on Auto ISO. If hand held, consider yourself lucky the pictures are as sharp as they are. Handholding at 1/25" usually produces OOF pictures unless you're very steady and your lens has very good image stabilization.

Because you were set on auto iso and hand held there is a chance that you focused on a different shade point. Not really to do with live view its about using auto ISO.

In a mirrorless camera what you get in the electronic viewfinder is what you see on live view when you move your eye away from the camera....

What a lot of 'long exposure' photographers sugest is that you cover your view finder to stop light entering there and ruining your shot - don't know if that holds with live view or mirrorless....

Question is whether using live view and an uncovered viewfinder alters auto ISO and the only way to prove that would be to put your camera on a tripod and lock focus. then take one shot in live view with a covered viewfinder and one shot without covering it and see what Auto ISO has to say about that....But it would prove very little as AUTO anything usually has many variables at work and may bounce around seemingly at random.

Pick your ISO
