I carry a camera with me most of the time.
However, when something "good" is going on. I often don't get the chance to get the camera out.

We are required to take pictures here as inspectors for evidential purposes, but I often end up never getting the pics back.
Having said that, I have seen a LOT of good work here, by home-owners and electricians alike, time management dictates though, that you'd better get onto the next job, if you want to be in bed before midnight.

Other side of the coin, I did find even a cheap camera, extremely handy for new construction, in case the Gib- stoppers covered all your boxes over, you instantly had some sort of a reference to start using a hammer, when you came back a week or more later and couldn't remember where half the boxes should have been.
