Figure photography

Landscape photos usually use a wide-angle lens, which helps to express grand scenes. So choose lenses with equal focal lengths of 35mm, 28mm and 24mm. Other focal lengths can also be used to shoot landscapes, depending on the content. Landscape photography generally uses a smaller aperture to obtain a larger depth of field, so that all the scenes in the picture are imaged clearly and carefully. In the case of small aperture, such as F8, F 16, the imaging effect of ordinary lens is greatly improved, which is similar to that of expensive professional lens, and the investment of lens need not be too high. The camera lens of 350D is 18-55mm, which is equivalent to 28.8-88mm of 135, and its wide-angle end can completely meet the requirements of ordinary landscape photography.

Usually, a smaller aperture will lead to a slower shutter speed, and obtaining a clear picture requires a higher stability of the camera. If the shutter speed is slow, you can shoot with a tripod. In order to meet higher requirements, self-timer and reflector can be used for pre-lifting. EOS 350D fully supports the functions required for these advanced shooting.

The role of filters in landscape photography can not be ignored. Although digital images can achieve the effect of some filters in the film age through powerful post-processing, there are still two kinds of filters that are irreplaceable, that is, polarizer and gray gradient mirror. Polarizer is a kind of filter that can filter polarized light. Generally speaking, the light reflected by nonmetallic surfaces is polarized light. In the photos showing the water surface or underwater scenery, you can use a polarizer to enhance or weaken the reflection effect of the water surface, and you can use a polarizer to make the sky bluer. In many landscape photos, the sky is too bright and the ground is too dark, both of which appear in one photo at the same time, and the brightness span exceeds the range that the camera can record. At this time, the gray gradient mirror can be used to weaken the brightness of the sky and achieve the effect of relatively balanced sky and ground.

The above parts are effective for both film SLR and digital SLR to take landscape photos. Let's talk about the special skills of digital photos.

White Balance: The set white balance mode is normal daylight.

Under normal lighting conditions, the balance of sunlight and white will get photos with normal colors. But on cloudy days, the photos will be slightly blue. Low color temperature can make the visual effect of color dignified, and this characteristic can be flexibly used to express specific scenes when shooting scenes.

Sensitivity: Try to use a low ISO value and set it for special scenes.

Generally, the ISO value can be set to the lowest when shooting, such as 100 for 350D. In this way, a fine and low-noise picture can be obtained. In some special scenes, if you want to shoot the dynamics of the running water, you can set a higher ISO value to get a higher shutter speed to "freeze" the running water.

Storage format: RAW files should be used.

RAW files have many advantages in taking landscape photos, such as preserving image details to the greatest extent; You can set the color temperature and white balance of the scene lossless; You can get a higher exposure latitude and so on. If you use a large memory card, you can record files in RAW+JPEG format.

In-machine image parameter setting:

When shooting in RAW+JPEG format, the parameter setting of the built-in image plays a role in JPEG images. Usually, we will increase the contrast, such as one step on a sunny day and two steps on a cloudy day, to make the contrast sharp. Sharpness can be improved by a step, which is helpful to show the details of the scene. Saturation can be increased by one or two steps according to different scenes to obtain bright and strong colors. The addition and subtraction of hue parameters will affect the color of the whole picture, such as green when the color of the picture decreases and red when it increases. The principle of parameter setting of in-machine images is the same as that of post-processing by computer, so it is easy to use these parameters in application.

There are also some common techniques in landscape photography, such as peripheral exposure, post-secondary exposure and so on. These will be gradually reflected in advanced landscape photography.
