I have a LF companion to go out shooting with, and friends as well who shoot LF. My wife enjoys walking, so she will go out and walk around in the desert or mountains, while I fiddle around under the dark cloth. It is best to set a loose time table when out shooting, so that all know about constraints of time and are inagreement prior to the outing.
The companion is of a similar age and keeps her own counsel. We get along well because I tend to be more of a technician and she is more intuitive. When shooting in a shared area, we see different things and go off in our own direction. This has evolved over a couple of years which happened to coincide with my interest in LF. I think it helps to share a common interest, pure photography for its own sake, and allow that interest to expand in whatever direction it may take.
There is no distracion now, just an exchange of ideas about light and prints. It is enjoyable to see another person grow into their interest and see progress. This is perhaps as enjoyable as taking a good picture. tim
