1. TRAVEL LIGHT. This reminds me of Hermione's tiny hand bag from Harry Potter 7 movie that fits everything and anything under the sun. But we are not in a wizarding world, are we? Just like your previous regular travel, write down all you need to carry with you. Now remember your goal. Don't get carried away by bringing everything that's in your house with you. You don't want to miss every opportunity of perfect shots just because your hands are full. A wad of memory cards, a lightweight mini tripod, flash diffuser, durable camera bag that distributes the weight evenly over your shoulders and protects against heat, cold, sand and moisture.
2. TRAVEL LENS. Although not possible for the budget, best lens for travelling is 18-200mm or 28-300mm for fast zoom. Sometimes you'll find the focal point far off the distance, but other times it could be right under your nose. This is were a portrait prime lens comes in (e.g. 50mm or 85mm). For a wider choice, consider a wide angle lens (e.g. 10-24mm) and a telephoto (e.g. 70-200mm).
3. RAW AND JPEG. Either way, you need several high capacity memory cards. Get in to the habit of downloading your images to a laptop of photo storage device every night to avoid deleting photos that you don't even have plan on doing so on the first place.
4. NOTES. By the end of the day, take time to jot down a few notes about the day's events. This will help you when you come to add keywords and descriptions of the places, people, activities featured in your photos.
6. ASK PERMISSION if necessary. If your subject says NO, no big deal. If they say YES, fire away. Either way, just smile. They may be uncomfortable during initial frames so show them the LCD monitor and use this opportunity to check the histogram. Always sense when to stop and move on. If there's a language barrier - simply smile, again.
7. PREPARE FOR SAFETY MEASURES. Big time photographers take out travel insurance for them and their gear. But for starters like me, invest in solid luggage locks and anti-theft bags. Pocket a small amount of local currency in an easy-to-reach place and the rest of your cash elsewhere and keep a list of emergency numbers and phrases on your person.
8. BE DIFFERENT. When you google images for sample pictures, try to imagine yourself on the right spot where the pictures were taken and think of a better angle when taking the shots. Shoot from the floor with a wide angle or fish eye lens, climb a tower and shoot from above, wait for dawn/dusk - mount your camera on a tripod and slow the shutter speed to capture the landmark in beautiful light whilst incorporate the ghostly movement of tourists strolling by.
9.GET CANDID. That's the best shots when travelling.
