Yeah, my camera has been broken forever, and only one of us has a smartphone, so I'm grateful to have a photographer, but I pretty quickly learned that I had to review the photos before the end of the session. He's learned to take another if it's a goofy face now, but he doesn't tend to notice things like the wrong buttons unbuttoned, or uneven pants rolls, or collars inside out, let alone weird angles. I really didn't need the underside of my butt as the focal point of a shot...
Also cat interference is an ever present danger. I admire those who have cats who sit by observing without wanting to get their owner's attention by clawing their tights for example.
