I was going to mention a shoemaker without shoes--a Russian expression--until I realized that the English equivalent, “The cobbler's wife is the worst shod,” was quite similar (not unlike a number of other languages).

Photographers rarely have decent images of themselves, and those are often self-portraits taken with the use of a timer (at least in my case). Sometimes, there are exceptions, such as this photograph of me.

I suspect that the gods of rock'n'roll had a hand in its creation!
