The changeable combination of light and shadow in nature provides infinite creative possibilities for landscape photography. The types of light include direct light, diffuse light, side light, backlight, top light, etc. In this issue, the blacksmith furnace teacher explains how to capture light and shadow from a technical point of view and shoots scenery works flowing with light and shadow.
1. Detailed explanation of weak light, warm light, diffuse light and direct light in landscape photography
The types of light can be divided into direct light, diffuse light, side light, backlight, top light and so on. For me who prefer landscape photography, I prefer to divide light into weak light before and after sunrise and sunset, warm light changing rapidly at sunrise and sunset, diffuse light in cloudy sky, and direct light from the sun hanging high in the sky.
1. The direct light of the sun hanging high in the sky, in addition to looking for small scenes in the woods, only one case is relatively suitable for the shooting of landscape photographs, that is, local light.
Fig. 1. Several cows came home in the evening when the rain stopped and the clouds blew a crack. Fig. 2. Roaming around the Toad Dam at eight or nine o'clock. Fortunately, the uneven thickness of clouds can change light.
3. The fast-changing warm-tone light at sunrise and sunset is the favorite of landscape photographers and photographers, and it is also the time when more films can be produced. Of course, the "cooperation" between cloud and fog is very important.
4) For the weak light before and after sunrise and sunset, we can take good pictures when we meet the appropriate scenes.
The last two pictures were taken while waiting for sunrise in the same morning. The former exposure time was 4 seconds, and the latter 6.3 seconds. At this time, a stable triangle frame is very necessary.
II. Filming Equipment
CANON cameras, including 5DII and 1DIII, were used until 2011. Hasu H4D-50 camera has been used since 2012, including HCD35-90 zoom head, 150 zoom head, 210 zoom head and 300 zoom head. The main purpose of replacing Hasu cameras is to make the photos bigger when they are printed, and to like their sharpness and clarity better. But as far as I'm concerned, the Hasu camera I used has a higher failure rate and more difficulties in low temperature use. Of course, it's normal to be bulky and inconvenient, consume fast batteries and charge slowly (it takes 12 hours).

Almost all use aperture first, and the camera automatically sets the shutter speed. However, for the subjects with large changes in light and shadow, the shutter speed of 1/2-1 gear is generally increased or decreased by compensation. After taking a picture, the histogram is checked. Then, according to the relative position of the color order curve of the histogram, it is decided whether it is necessary to adjust the compensation shutter speed again. Simply put, the aperture is first, the shutter speed is compensated and adjusted, and the two ends of the histogram do not overflow. Two points should be paid attention to at this time. One is that the color order curve is as close to the right side as possible without overflowing the highlight. The other is that it can not guarantee that the two ends of the color order curve are not overflowing to shoot two pictures separately to satisfy one end without overflowing, and then do processing later. In addition, due to lens diffraction, each lens has a suitable aperture range, and blindly pursuing large field depth and using a similar F22 aperture near the minimum aperture end may reduce sharpness more, but make the whole picture look a sense of ambiguity. Also, try to get used to checking the color scale. It is difficult to grasp and judge the picture taken from the camera display screen because of the influence of the angle and brightness of the ambient light; using high-light overflow alarm is very simple, but it is difficult to accurately control the right and left position of the color-order curve; while the color-order curve is simple and intuitive, the scene only needs to ensure that the two ends of the color-order curve are not overflowed. That's fine (if the sky and the ground take two pictures separately, that's another matter).

4. Utilizing the Fog at the Peak or Foot of a Mountain
The sun had not yet appeared, but the sky began to redden slightly. Observations showed that the fog at the top and foot of the hill far to the left of the plane was flowing, jumping, changing rapidly, and reflecting a little color of the sky. Immediately replace the camera equipped with 300 mm (equivalent to 211 mm of 35 mm full frame) long focal lens and take a group of photos. The following pictures are two representations of cutting and other treatments. Note the choice of shutter speed (2.5 seconds above and 5 seconds below), and different shutter speeds will show completely different effects of morning fog flow and change.
5. Capturing Changing Light with Long Focus before and after the Sun Rises
Before and after the sun rises from behind the mountains, it is a very short and best time to shoot. I must grasp the time. After taking a panorama, I immediately change the focus lens to shoot a group of beautiful scenes with changing fog and light.
6. The color of the morning fog fades and the dim light and shadow are taken.
At this time, the Sun continues to rise, and the color of the morning fog fades quickly. In the process of downhill along the hillside, I stayed twice to shoot small scenes on the opposite side and side, which has a special charm.
7. Creating Special Artistic Conception Scenery in Later Period
It is also possible to deliberately shoot works of special artistic conception when there are adverse weather conditions, including the cloudy days mentioned above, as well as relatively flat and windy weather. Then use the latter dry brush to deal with: clear trunks, shaking branches and shaking leaves.
The wind is strong and the sun has set. The woods are very rich in color, 3 seconds exposure, later dry brush processing: clear trunk, swaying branches, swaying leaves.
