Finally, assuming you camera hasn't been lost, stolen, dropped in the sea, melted by boiling lava or sent to Punta Arenas along with the rest of your luggage, here are some tips to help you take better holiday pictures with it.
First and most obviously, remember to take your battery charger and a mains adapter that will allow you to plug it in when you get there. Most chargers sold in Europe are multi-voltage and will work just fine with weird foreign electricity, but you'll need to be able to plug it in.
Also, if you've bought a new camera to take on holiday, take the manual with you. If you've bought a Canon and all the useful bits of the manual are on a CD, print out the pages dealing with the different shooting settings. You'll get better photos if you know how to use your camera properly.
Since you're going to be buying a camera pouch or case to keep out the sand and pickpockets, get one that's big enough to also hold some simple cleaning kit and a mini tripod. If you want to include yourself in group shots, it's a much better idea to set the camera on a tripod and use the self-timer rather than asking a stranger to take your picture for you, especially if they're wearing running shoes.
Most holiday photos are just random snaps of the scenery to remind you of where you visited, and while that may be all very well for your own purposes, but if you put in a bit of effort you'll get much better photos. Remember how bored you were the last time someone showed you their holiday snaps? Nobody else wants to see endless photos of people they don't know standing in front of places they've never been to, but most people will happily look through an album of good quality photos taken with care and imagination.
Try to find different shots than the ones that all the other tourists are taking. Everyone takes a photo of the Eiffel Tower from Place Joffre looking over the park, so why not try a different view? Maybe wait until evening and catch it against a sunset, or get up close underneath and try some close-ups of the structure? A bit of thought will provide you with much more memorable pictures. While your holiday companions may moan about you always stopping to take photos, you can guarantee they'll be asking for copies once you get home.
