First and foremost, think about what made you decide, out of all the places in the world, to choose this particular destination. Whatever it is—the beach, the rides, the mountain, the galleries, the food—obviously appeals to you. If it didn't, you wouldn't be going there. That site or activity (or inactivity) is one of the things you want to photograph. But there are probably many other interesting aspects of the place you may not be aware of. That's where research comes in.
Get out there. The only way to discover the rhythm of life in a place, and so figure out what to shoot, is to experience it. Many places, particularly hot ones, are active very early in the morning and late in the afternoon but rather in a lull around midday. Get up early, stay out late. If you are on a tour that is scheduled to leave the hotel or ship at 9:00, get up well before dawn. Wander around before meeting up with your companions. If the tour goes back to the hotel or ship for lunch, don't go with them. Rather than take the bus back at the end of an afternoon tour, hang around until after sunset and then take a taxi. Use any spare time to get out and look for photographs. Besides availing yourself of more opportunities, time spent discovering the place will enrich your experience.
Hi Claire, thanks for your message. That’s correct, it’s not possible to upload photos from your computer to Instagram however it’s quite popular to get around this by emailing the photos to yourself, then opening the email on your phone and storing the attached image in your phone’s library. This then allows you to post to Instagram. Alternatively there are a number of apps or plugins that allow you to upload to Instagram, most however will require payment. This is one I suggest looking at ‘LR/Instagram‘ but I can’t promise anything as I don’t personally use this method.
Make use of people to give your images life and scale. If the facade of a particular building appeals to you, the picture may be that much better if you show people walking in front of it. They will give it scale and also let viewers know what sorts of people live there, how they dress, and the like. An outdoor café may be more interesting crowded with people than empty.
