It's summer, time for travelling and also peak season for nature and travel photography. Digital cameras are still getting better and better and easier to use. However, sometimes it is quite disappointing that a picture such as a historic city alley either is partly underexposed with huge dark shadow areas, or the roofs and the sky are extremely overexposed. Although it is possible to review the image immediately in the display on the camera, the problem can often only be addressed at home in the post-processing workflow, and then it might be too late to fix the image in order to get a beautiful photograph.
Many travel and landscape photography pictures have very high contrast. "Dynamic range" is the term for the range of light intensity from the darkest shadows to the brightest highlights and it is measured in "exposure values" (EV), also commonly called "stops". Our eyes are able to adapt to see high contrast scenes but the dynamic range of the sensor of a digital camera is limited. Unfortunately the dynamic range of monitors, photographic paper or print is even more limited. A dynamic range of an image of about 8 to 9 EV is usually no problem. Experienced photographers can handle dynamic ranges of 10 to 11 EV quite well with exact exposure settings and with the help of calibrated monitors. But what about high contrast scenes with a dynamic range of 14 EV and higher? In particular landscape photography offers a wide range of high contrast scenes: idyllic sunsets by the seaside, backlit photography or scenes in high mountain regions.
An important rule in photography is to avoid high contrast in the first place. Many professional landscape photographers shoot only early in the morning or between late afternoon and evening because the light is much softer. Long shadows can be avoided when the sun is at the back of the photographer. Foreground subjects in backlit photography should be placed in front of a dark background because the high contrast can only be recognized as a small light fringe around the foreground subject. Long shadows might be wonderful for creative photography, but the final picture should offer enough details in dark shadow areas as well. The dynamic range of a scene can be simply reviewed with the help of the brightness histogram on the rear screen of the camera or manually calculated with contrast measurement. If the dynamic range of a scene or subject exceeds 10 or 11 EV the photographer should probably try out one of the following approaches.
The Tazaungdaing Festival is a traditional festival and public holiday in Myanmar. It is also known as the "Festival of Lights" and it is celebrated on the full moon of Tazaungmon, the eighth month of the traditional Burmese calendar. The Tazaungdaing Festival marks the end of the rainy season. In Taunggyi in Shan State hot-air balloons lit with candles are released to celebrate the full moon day and the Tazaungdaing Festival. It is comparable to the Yi Peng and Loi Krathong celebrations in Thailand.
However, the Taunggyi Balloon Festival it much more than a public holiday. It lasts around 6 or 7 days and it is also a balloon competition and funfair at the same time. Traditionally the festival ends on the full moon day Tazaungmon with the announcement of the winners of the balloon contest. The balloons are beautifully designed and hand-made of traditional mulberry papers and bamboo. They are released day and night during the festival. The balloons for the daytime competition are smaller and usually have the form of pagodas, ducks, dragons or even elephants. The bigger balloons decorated with candles are released at the night time competitions, sometimes even with attached fireworks that explode into the night sky.
According to the Tanzanian Albino Society the estimation of people with albinism living in Tanzania today is between 180,000 and 270,000. Albinism is an inherited gene disorder, the albino gene is recessive and stops the production of melanin in the skin, hair and eyes. For the Tanzanian albinos it means that every day is a big challenge. They have to protect their skin from the strong sun which can easily cause painful skin burning and could result in premature death due to skin cancer. Albinism is often associated with vision defects like involuntary eye movement or the absence of an iris in the eye.
Albinism is a disability and as there is no cure it influences massively the daily life of the affected people. It starts in primary school where children with albinism are often rejected by their fellow students. For adults getting a job is very difficult. Traditional field work in the merciless African sun is almost impossible for people with albinism. Many of them end up in their own little shop, they sell fish, fruits or vegetable on the local market, or they work as merchants or salesmen. In Tanzania there is no social security, and although albinos are handicapped they don't get any money from the government.
