This book let me know some terms, such as the essential function of white balance, and the most rewarding thing is that when you see beautiful scenery, don't just press the camera crazily, but think clearly about what you want to express.

Key points:

1.？ Take a big shot and aim at the front 1/3 to ensure the overall clarity of the photo. If we focus on the distant scenery, it will not conform to the perspective seen by human eyes.

2.？ Take a single peak and focus on the peak.

Manual focusing: at night, backlight,

Multi-focus: dynamic objects, static scenes

Single focus: Specify the focus position.

Free focus, most subjects.

Extended free point: small size, small motion range, (swinging dog tail grass)

Intermediate focus: 45 focuses (group photo, large depth of field. But it is not appropriate when there is an obvious fit)

Static flowers, portraits and landscapes: single autofocus+single focus

Motion: continuous autofocus

Lock the focus: first press the shutter half to lock the focus, and then press it. Only suitable for big landscape photos.

Photometry: Multiple photometry is similar to average photometry, but the former is better.

Central metering, people, documentaries, scenery

Spot photometry

Strong light (ensure that the highlighted part will not explode)

White plus black minus: Because the camera is based on the reflectivity of 18%, the reflectivity of snow is greater than this value, which will darken.

White plus scene: snow, strong light, white multi-scene.

Black reduction: low light and more black at night.

AEL is the key to lock the exposure (for spot metering and central metering). Press the shutter to determine the focal length. At the same time, the camera measures light, and locks the measurement data of the subject by pressing AEL to avoid the interference of light when re-composing.

When the scattered light is small, the exposure difficulty becomes smaller, but the contrast between light and dark also decreases, which can be guided by composition.

DRO/ automatic HDR dynamic range: when the contrast of light is large, the purpose is to keep the details and levels of shadows and advertisements, and use it in combination with multiple photometry.

Depth of field: aperture, focal length, object distance (the photographer is in the subject) and distance (the subject is in the background).

ISO daytime 100-400, shading 400 is also enough.

Flap the object, the shutter is fast, and the iso should be improved.

What is white balance?

In general, people can use white as a reference to distinguish other colors. Adjusting white balance refers to restoring various colors based on white.

In different environments, the standard of white color reproduction is different. For example, the white of indoor fluorescent lamps should be blue, and the white at sunset should be red and yellow. At this time, if there is standard white or blue and white to restore other colors, it will be uncoordinated.

If the set color temperature is higher than the actual color temperature, it will be red, and if it is lower than the actual color temperature, it will be blue.

Creative style is the style set for JPEG output. For example, the saturation of green grass and blue sky will increase, the clarity and contrast of photos will be higher, and the picture will look brighter. If it is set to portrait style, the brightness, saturation and contrast of JPEG format will be slightly higher to ensure fair and balanced skin color.

Color space, generally set to SRGB, ah Adobe RGB is more convenient for post-processing and has a larger color gamut.

Adding black and white will also affect the color. Usually, people add a little white to improve their skin color.

Three skills of subtraction in photography: three points of depth of field in block subtraction J.

Direction of light

Sunlight lacks light and shadow levels, but it can preserve the surface details of the scene. Photometry: Three-dimensional trees, desert water patterns.

Oblique ray

The top light is not suitable for people, because the top of the head, forehead and nose are very bright, and the lower eyelids and nose are very dark. But in some dark scenes, it can bring great contrast. Such as old buildings, valleys and dense forests.

When shooting a scenery film, don't snap it as soon as you see the beautiful scenery, but think about what is the center of the picture. Let him run through the whole picture, which can be people or things, such as buildings, branches, an outline and so on.

You should try all kinds of weather. You can photograph the reflection of a rainy day, the water drops on the glass as the foreground, and the fog can create dreams and cumulonimbus clouds before the rain.

Straight to continuous shooting.
