How many ECs take a digital camera with them on the job?

In my line of work (computer consulting) I've run across some "disasters in the making", and decided that it might be best for me to document the situations before I touch them, for my own protection. And a lot of my work involves setting up and cabling in computers (and a few 120V power strips). What I do, I will leave it in the right condition (or won't take the job). But if I'm not hired to re-do the whole place, there is the risk that something else I didn't work with could go wrong and be blamed on me.

I might also expect that ECs that do jobs they are proud of would like to make a record of that, too, and maybe even post it on ECN (I like to see quality work in any trade). And it might even be good to record the work you do in case some handyman comes along, later.
