As for photographic technique, we would recommend you as follows:
If you want to make sharp photos at any time of night and day do not forget to take a tripod. The total weight of your backpack with all photographic equipment should not be more than 13 kg. It is good to have both wide-angle and telescopic lenses. Best of all it would be to take a high quality zoom lens than a park of discrete ones. Do not take lenses covering more than 500 mm focal lengths. Their use in such trips is extremely limited, therefore, it is no need to add the weight to your luggage. During the last photo-tour Yuri Afanasiev used a set of "top-end" Sony Alpha optics covering from 16 to 560 mm focal lengths.
Except a number of memory cards take a storage device to keep your photos.
Do not forget to take a battery charger for all your devices requiring power supply. It is also desirable to have a spare accumulator for your camera.
A flash light for night photographing and water-proof bags to keep your equipment dry in case of rain or travelling by boat are also be of use to you.
But the most important things you shouldn’t forget to take with are a sun-protection cream, sun glasses and light comfortable clothes covering hands and foots.
