Rethinking Auto. Is Using Auto ISO a Bad Thing?

I used to believe that the Auto setting on a camera was something to be avoided the way a tired waitress avoids eye contact when you’re signaling for a coffee refill—she can’t deny that you’re there, but she can ignore the hell out of you. I still feel that way about fully auto exposure, but my maniacally stubborn attitude toward Auto ISO is softening like marshmallow Peeps in a microwave.
