Ask permission before you photograph local
people - in some countries it can cause offence
Do buy plenty of film
before your trip as it may be hard to find and/or very expensive.
Do not
take photographs in any military area, airports, ports, border crossings etc.
you are like to have your camera taken away.
don't take photos of
bridges, harbors, military installations, army personnel, railway stations,
airports, border crossing etc., If you do, you might be arrested and you are
likely to have your camera confiscated..
if you print photos locally:
don't send home the negatives in the same bunch, but in a separate mailing for
extra safety
