To reset the ISO selection on the N90s:
0) Turn on the camera.
1) On the left part of the camera top, look for the ISO button.
It's the right most of the cluster of four buttons.
2) Press down on the "ISO" button, and simultaneously rotate
the command dial (the dial on the right side of the camera
top). As you look into the LCD window, you'll see the
film speed change.
3) Rotate the setting up (or down) until you get to the position
between ISO 6400 and ISO 6. That setting is the automatic
DX setting. You'll see the DX indicator light up right below
the ISO indicator.
4) Enjoy shooting the N90s again. It's a great camera!
