Before going for photographic tourism, one must be aware of the local customs and practices. There are many amazing touring destinations around the world where taking photos of local inhabitants, temples and shrines or a traditional ritual would invite public resentment. Here, it is wise to show respect for what is a taboo and keep your camera locked. However, you may always make a request and seek permission beforehand from the competent authority if you really feel your trip would lose half its spirit by not taking a photo, which you so much crave for. This will not cost you more than a few polite mails and words of requests.
You need to decide whether to use a digicam, a DSLR or a film supported camera. If you are going to take a large number of shots, it is wise to take a digicam as it will save you enormous film processing and film development costs associated with a film supported one. The initial investment on a digicam is a bit high, but with a large number of photos shot the cost graph steadily goes on a downward slope. On an economic scale, we may put it this way!
If you are off to a mountainous tour destination like Nepal, Tibet or Darjeeling or Kumaon in India, which gives you an access to view the legendary world famous and awe inspiring snow capped summits like Mt Everest, Mt Kanchenjunga and Mt Nanda Devi, take a camera with a high zooming power. These chains of mountain peaks stand at a great distance, and you certainly need to bring the image closer to catch the finer details like crevices and cracks distinct throbbing with life!
You should plan to take with you a sufficient stock of film and batteries. Countries having a low climatic temperature eat into your battery life faster. Needless to say, you should guard your camera properly so that the lens does not get a scratch! Guard the lens with a cover and carry delicate pieces of cloth for careful cleaning of the lens.
One important factor to be borne in mind is the weather conditions of the tour destination. Heavy downpour is a major hurdle for good photograph. Your endeavor with your camera is lost in the haze of heavy drenching sheets. Whatever may be the character of the landscape or a seaside resort, heavy rain will mar the spirit of photography. So try to avoid photographic tourism in the rain and wait for a bright sunny season.
If you are carrying a tripod, see that they come handy and neatly fit into your luggage pack. You may opt for mini tripods as they do not lend an additional weight to your luggage. They are actually depending upon the kind of photography you are going to take. They are ideal for shots of sunrise and rolling waterfalls.
If you are carrying a DSLR camera on a photographic tourism, check that the camera and its parts are tightly packed. You may get a padded case having separate sections to fit in the different kinds of lens and keep them in place tight and safe. Else they may get damaged while hurrying towards airport or boarding a transport. Check the functioning of your camera and battery charger well ahead of your trip. You may need to spend a little bit on replacement of parts, which should be factored in while preparing for photographic tourism.
