Thanks to both Ben and Brian for sticking with me on this hard to explain situation.
It has DEFINITELY helped me, both in learning the camera operation, and in relieving a bit of fear that I had a malfunction.
I also recall a post from another Nikonian that this post helped that person understand some nuances of camera operation as to Easy ISO. That is how I often feel reading the posts here, and why I keep reading them.
THANK YOU ALL AGAIN!
Now, I think I shall sneak off to "lunch" early and take the D600 for some more practice shots, and run the ISO functions through their paces! Nice light here today.
