What filter is good for landscape photography?
Landscape photography filter
Graded neutral density (GND)
Usage: control the intensity of light and control the light difference.
Purpose: to deal with the situation that the gap between light and shade is too large in landscape photography.
A gradient lens can gradually reduce the brightness of a photo from a certain position (mostly from top to bottom). This filter is very suitable for some landscape photos with simple light difference, such as sunset photos (the sky near the sun is brighter and the position near the ground is darker).
When digital photography is not popular, gradient lens is a necessity for every photographer. At present, many digital cameras have HDR function (combining photos with different exposures), but the effect is not the same as that of gradient lens and cannot be completely replaced.
Polarizer (polarizer)
Purpose: Filter reflected light.
Uses: Photographing water, shop windows, plants and the sky.
Polarizer plays a very important role in taking landscape photos. Its main purpose is to eliminate the reflection of different surfaces and make the blue sky bluer and the trees greener. In addition, it can also reduce reflections on water and windows.
To understand the principle of polarizer, we must first understand that light propagates in waveform, and the normal direction of light wave vibration is not limited to a single plane direction, but comes from all directions irregularly. But under special circumstances, that is, after reflection, the direction of light wave vibration will become a single direction.
Because the polarizer only allows light in a single vibration direction to pass through, the light waves in other vibration directions will be blocked after adjusting the angle of the polarizer. Filter? Put it down. When the polarizer forms a certain angle with the reflected light, the reflected light is naturally eliminated, thus reducing the reflection.
There are several points to pay attention to when using a polarizer: because the polarizer only allows light in a single vibration direction to pass through, the intensity of light decreases accordingly. That is to say, under the same light source, a camera with a polarizer needs long exposure (assuming the aperture is constant). In the case of hand-held camera shooting, the hand shock effect will be more obvious. If you use a polarizer in a super wide-angle lens, there will also be uneven light and dark.
Warm color mirror, cold color mirror (heating up, cooling down)
Usage: Change the white balance of photos.
Uses: landscape photography, underwater photography, photography under special lighting.
Cold and warm lenses can change the color temperature of photos, which can be used to correct light or make photos show wonderful colors. For example, add some warm colors on cloudy days to make the photos look more like those taken at sunset.
Neutral density
Objective: To reduce the amount of light entering the lens.
Usage: Shoot waterfalls and rivers under strong light.
ND mirror can reduce the amount of light projected on the photosensitive element on average. When the settings of your camera (aperture, shutter, ISO) can't further reduce the amount of light entering the camera, or you want to get a slower shutter value or a larger aperture value under a certain setting, the nd mirror comes in handy.
ND mirror is mainly used under the setting of slow shutter, such as: shooting silk-like running water in the sun to make it more dynamic; Make moving objects (such as people and cars) inconspicuous or even disappear in the image; Increase the dynamics of moving objects, etc.
Note that some poor quality neodymium mirrors will make the photos have color cast, and different manufacturers have different expressions on the dimming amount of neodymium mirrors, so pay attention when using them.
Ultraviolet reflector (ultraviolet ray, haze)
Objective: To protect the lens.
Usage: Use at any time.
In the era of film machine, UV mirror mainly improves the contrast of photos by reducing the ultraviolet rays injected into the film. Nowadays, in general digital cameras, the photosensitive element does not record ultraviolet rays, so it is no longer necessary to filter ultraviolet rays, which is mainly used to protect the lens.
Landscape photography skills
Build a picture frame
Composed of prospects? Frame? Can effectively guide the audience's attention to the main body. Notice the different shapes and sizes? Frame? Not only windows or fences can be used. For example, in this photo, big trees are made up? Frame? .
Avoid the horizon in the center of the picture.
First, ensure that the horizon is horizontal; Secondly, don't let it appear in the center of the picture. If the sky is more interesting, let the horizon be lower; If the earth is more interesting, raise the horizon.
Bring life to photos.
Try to add something vivid to the photo. They can emphasize the size and proportion of the picture to the audience.
Avoid the intersection of vision.
If the horizon intersects with the subject, it will distract the audience, and in serious cases, it may ruin an excellent composition. Take some time to change the shooting angle to avoid this situation. In this illustration, I pay special attention not to let the horizon coincide with the edge of the barn.
A single theme is eye-catching.
Single theme? Like trees, barns, buildings, or motorcycles? You can always compose an excellent composition. I like to put them in photos. This picture is an illustration. There is only one solitary tree in the picture.
This is about size.
Try to take something in the picture that can provide the audience with proportional information. People or things let the audience intuitively feel the size of the picture, such as the car in the illustration.
Think before you press the shutter.
Thinking before pressing the shutter applies to any kind of photography. Specific to this article, it is to make sure that there are no irrelevant objects in your composition. If possible, remove those objects, otherwise move yourself and try to avoid them appearing in the composition.
Remember the dichotomy.
If you want to improve your composition, this is a basic composition skill that should be remembered. People's eyes usually fall on one third of the picture (up, down, left and right). When writing a composition, you should always remember this rule.
Space is your friend.
Don't always try to fill the picture with themes. Setting aside a certain space can add a lot of color to your photos. Remember, space is as important as theme.
Make good use of geometry
Train your eyes to recognize lines, patterns and shapes. These elements can increase the sense of structure of photos and help to highlight the three-dimensional sense of the theme. Lines can guide the audience's eyes, focus on a topic, and then find lines that can point to it.
