摄影入门基础知识光圈快门感光度及拍摄技巧（Basics of Photography aperture, shutter, sensitivity, and shooting skills） Aperture lens aperture size F1.2, F1.4, F1.8, F2.0, ~F5.6, ~F11 ~ F22, commonly used values are larger or smaller The smaller the aperture, the larger the aperture and the opening from large to small The smaller the aperture, the lower the background, and the larger the aperture, the more realistic the background is from virtual to solid The aperture will affect the brightness of the picture Shutter (shutter speed) 30, ~1/4000, 30 sec to 4000 of a second (split one second into 400 parts), from slow to fast The shutter speed will affect the picture quality of the map. For example, long time exposure handshaken The sensitivity of ISO100, ISO200, ISO400, ~ISO12800 is not enumerated from low to high Drawing quality from high to low noise and more high sensitivity Its important, but the camera doesnt have the light source. Its only up to you. The exposure compensation is not here. Ill talk later. Tell a little story: have you heard about the math problem of the reservoir? Will you carry it back?. Ha-ha。 How often do you fill up? I feel that photography is like water storage. Light is water and light is the source of water Sunny, sunny, large amount of water; cloudy days, less indoor, the night is naturally the least. Aperture is the water gate, F1.8 opening large (unit time, more water, faster), F22 small opening (unit time less water, slow speed), the shutter is the time to release water. 30 seconds, long drainage time (careful exposure, pool full of water, put a lot of spilled land). 4000 seconds, just put a drop will not water, black screen nothing. There is the stability of water storage, short time is stable, long time is unstable, spilled out. Sensitivity is the size of the pool, iso100 large pool of water more than the blue yo, ISO high value, shallow pool. The four factor is what you want. The objective condition is what kind of weather the weather gives you. Sunny, su
