Also, how do I change the ISO on my Nikon d7500?
The button is the ISO button on the top, justbehind the shutter. While you're holding that button down with yourright index finger, use your right thumb to rotate the dial on theback. You'll see the ISO setting change both on the topscreen and through the viewfinder (or the back screen if you'reusing that).
