Take more pictures. The relatively small amount of extra money you spend will result in a lot more results. There is little point in spending large sums of money on a camera only to avoid putting film through it. This is one of the great things about digital. You can take thousands of photos and it won't cost a thing.
Try different angles and see what you like. Try something really off-beat. Did it work?
You may only have one chance to visit a place, experience and see something. Be ready. Make sure that you get it right and don't come away disappointed.
Quality & Quantity
Always buy good quality film and always buy 36 (40 if APS) exposures. This will almost always save you money both when you buy the film and when you get it developed.
Stick to the major film brands. One main reason to choose these brands is that every lab in the world has their machines calibrated for these films so you will get the best possible results. Picking a lab can be difficult. Some professional labs are awful and some mini-labs are just great. Try one film first and see how they go. Never put all your films through one lab without first testing them.
When buying digital media always buy as high capacity storage as you can afford. The cards that come with most cameras are almost useless and will usually only give you a handful of shots. Keep this as back-up media for when you fill you main card up and need a few more shots. Batteries are also very important with digital as most cameras drain them in a few hours of use.
Cool & Dry
Keep your film cool and dry at all times and process your film promptly. This ensures that the colours remain as true as possible. A hot place like a car glove compartment can turn your film bright pink in hours.
If you are travelling for a while don't wait to get all your film done when you get home. Always process a roll or two along the way just to make sure that your camera is working. When you find a good lab process all your film and send the prints home and keep the negs with you. Many labs will now make a CDROM of your negs as they print them. This is another excellent back-up.
Digital media has some distinct advantages for travellers. You can back them up at Internet cafes and send the CD-R home. They don't get damaged by x-rays and normal heat. I now shoot only digital when I travel and don't miss the hassles of film.
