Fly the way the pro would fly
Your in a dream world if you think it doesn't happen.
You just have to go to youtube to see all the vids done in the cockpit by commercial crews.
in fact I am happy to admit I took a few shots in the cruise of the FO flying so he could send them to his granddad the other week.
And when doing photo survey we quite often fly the plane while hanging it on its ear in a side slip to get the wing out the way sometimes with the door off and take photo's at the same time.
Totally agree with MJ on this one commercial pilots do all manner of things especially on boring bits of the cruise from taking pictures to doing the crossword.
From memory I think the FAA made it illegal to use any electronic device which was not specific and needed for the flight and as such a camera or mobile phone would be illegal.
But then there are many boring parts of the flight where usually phones are used to capture various sky scapes.
On the approach to landing or takeoff when a pilots full attention is required for the job in question its not too clever to be snapping away but even then out of sight out of mind and with the autopilot its very tempting to grab a stunning scene even with commercial pilots
