To my knowledge, only the USA has explicit regulations that require hand inspection of photographic materials upon request.
I have sometimes encountered courteous operators at foreign airports that would honor that request, but usually not.
To get from the sidewalk in front of Munich Airport to the physical aircraft for a non-stop flight to Chicago, my hand baggage was x-rayed three times: front door, when checking in at the ticket counter, and just before boarding.
Luckily, I had no film with me on that trip.
