Appreciation of poverty alleviation photography in Tibet

The Qinghai-Tibet Plateau has always given people a mysterious and magical feeling. Rich and colorful colors, vast and changeable landforms, video is a must to travel there.

Tibet is a photographer's paradise. It is a place where you can never get enough of natural scenery and countless human details. However, it is exactly what photographers pay attention to when shooting scenery on the Qinghai-Tibet Plateau. Below, Chongqing Bian Xiao will share the plateau photography strategy that outdoor photographers must know!

These little experiences I share now are just some skills, hoping to help you, especially when shooting outside the plateau, to improve the film production rate.

First, the classification of the selected lens

Lens selection: Generally, we will have the following lenses to choose from: wide angle, medium focus and telephoto.

There are two kinds of tourism photography: one is to take pictures as a souvenir of "visiting here", and it is mainly based on records; The other is to take photography as the other eye of tourism discovery, focusing on creation.

If you belong to the former, it is enough to have a perfect "fool" camera or a mass camera with a fixed lens.

But if you are an amateur photographer, the following equipment may be necessary: one or two SLR bodies with good performance, so that two lenses with different focal lengths can be used at the same time (including wide-angle and medium-telephoto), and others such as flash, hood, filter, balloon brush, spare battery and small notepad are also necessary.

You should bring enough batteries, memory cards or digital companions. Although the use rate of tripod is not high, it is essential for shooting night scenes and stellar orbits. It can be decided according to the situation.

Wide-angle is suitable for shooting scenes, and the representative focal lengths are 12-24, 16-35, etc. Medium focus is suitable for shooting scenery and cultural representatives, with a focal length of 24-70 or 50, 85; Telefocus is suitable for shooting human representatives with focal length of 70-200 or 80-400. And it is best to shoot birds and beasts with a focal length of more than 400.

The plateau is a very special place with strong light ratio and contrast, so you must make some necessary preparations before you decide to shoot at the plateau.

Suggestion: Generally, Tibetan landscape photography should choose wide angle and telephoto, such as 16-35 plus 70-200 lens, so that most subjects can be photographed.

In Tibetan areas, we can use almost all filters, so it is suggested to prepare a whole set of filters, including gradient filters, subtractors and polarizers.

1 gradient filter, also known as GND.

As we know, landscape photography often competes with sunlight, and the camera can't balance the bright sky and the relatively dark ground in a large range like the human eye. So there is such a filter. The upper part is dark and the lower part is transparent to balance the highlighted areas in the sky. This is GND.

GND is varied. From the point of view of classification, there are generally several categories: first, if it is divided by shape, there are circles and squares. Secondly, if divided by dimming concentration, there can be several grades, such as 0.3, 0.6, 0.9 and so on. The concentration of 0.3 is the shallowest and then increases one by one. Finally, according to the level change of the dimming part, it is divided into soft gradient and hard gradient. The density in the soft gradient filter is decreasing step by step, the top is deepest, and the dividing line is already very light. The concentration in the hard gradient filter is basically the same, and suddenly it disappears at the dividing line. These two filters can be used in different environments. Of course, there is also a special gradient mirror called RGND, whose dark matter concentration is opposite to the soft gradient, with the shallowest top and the deepest boundary. This filter is suitable for shooting sunrise and sunset scenes, because the sun is near the horizon at this time, and the sunshine in the middle is the strongest.

2. The ND mirror that extends the exposure time is also called the medium gray mirror. In fact, it is a whole layer of dimming substance in the filter to extend the exposure time of the photo. The length of extended exposure time varies with the concentration of ND, so there will be a label after ND, such as ND2, ND4 and ND8, which is equivalent to negative one exposure, two exposures and three exposures. The algorithm is also very simple. For example, the exposure time of my current photo is 1/60s, so the exposure will be extended to 1/30s after using a piece of ND2 and1/5s after using ND4. The current exposure time multiplied by the number of ND tags is the actual exposure time.

3. Polarizer, eliminating the reflection of CPL light is a wave, so it has the characteristics of wave. The function of polarizer is to let only the light with the same vibration direction and gap pass through, so as to eliminate partial reflection. There are two kinds of polarizers: circular polarizer and linear polarizer, but because linear polarizer will affect the metering system of camera in structure, CPL is the most commonly used one since the digital age.

Perhaps the above paragraph is too vague, so please remember that the biggest function of CPL is to eliminate the reflection on the surface of non-metallic objects, such as water and mirrors. So if one day you want to shoot your own big aluminum pot happily, but you find that the reflection is too strong, it is totally impossible to use CPL. Of course, CPL also has the function of increasing saturation, but it is beyond the scope of our discussion today.
