Object (Focus) + light (quantity, quality, bit, ratio, color) + composition (plane, space). 0x01 recognize Exposure

1. What is photography: the process by which light is drawn, that is, by the light reflected by the object, the photosensitive medium is exposed. (by light to represent the shape of an object, the texture of the body color.) ）
2, the target starting point: Control the light, so that the brightness distribution is reasonable, that light can not be overexposed, dark can not be a piece. 0x02 Control Exposure

1. Aperture (amount of light): the larger the aperture, the smaller the depth of field.
2, Shutter (light duration): High shutter solidification moment, slow shutter record track;
3, ISO (CMOS photosensitive speed): The higher the ISO, the more noise. 0x03 camera lens (recognize focus)

1, image quality: Fixed focus lens quality, zoom lens convenient. (Fixed focus look away, zoom guard)
2, Focal length: the lens can see the range of how much. The shorter the focal length, the greater the range. (A wide-angle <24mm landscape with large depth of field, B standard ==50 and human eye similar still life products, C medium Tele 75~135mm,d long Gio small items)
3, the focus: the main body clear, the background of the virtual. /single region and dynamic area.
4. Focus Mode: AF: Af-s (Single), Af-c (auto-focus of moving object), af-a (two kinds plus) 0x04 photography

1, light quality: direct light (hard light) directional level sense of three-dimensional feeling strong, light and dark contrast large; scattering (soft light).
2, the light position (directionality and angle): Light metering backlight light bottom light.
3. Light ratio (light ratio of the subject's surface light): Fill light to control contrast.
4, white balance (light color): the reduction of white objects, that is, 5200k*2-color temperature (color temperature: The lower the color temperature, the more red colors. ) 0x05 Composition Basics

1, King: Take its potential, nearly take its God.
2, angle of view (see Angle): High (distant, broad, large scene) + low (the main body tall) + flat (most conservative). Perspective (three-dimensional representation on a plane): the visual direction of the line embodies the sense of space and depth.
3, the future: strengthen the atmosphere + increase the level of image space + balanced screen. Background: Highlight theme + Rich connotation. how to compose a 0x06

Plane composition: How to arrange people's scenery in the picture to become a whole.
(Point: Throw to the golden Section; line: Linear space sense, curve form beauty; face: Emphasis and emphasis, proportion.) )
Learn Composition: Observing imitation----classic rules----------seek breakthrough.
Portrait composition: The body position and the percentage (scene). 0x07 Common Themes

Sunrise and Sunset: location (open, high altitude) + time (Spring and Autumn) + metering + composition.
Waterfall: high-speed shutter water condensation, slow shutter fog-like flow. Filter (light reduction mirror) + low ISO (detail performance).
Fireworks: small aperture (large depth of field) + manual focus (to infinity) + Press shutter time (2~3s) + tripod (Stable) + downwind position
Night portrait: Control the ambient light + flash (external fill light more evenly, three-dimensional sense of layering) to highlight the main body.
