How to improve your SLR photography ability quickly

Lead: After buying a camera, you should read the instructions. Although the manual of the camera is very thick now, it is still necessary to read it, because the manual is a good helper for everyone to familiarize themselves with the camera. Every key of the camera and the special function of the camera can be found in the manual, and it is very clear.

Understand the relationship among ISO, aperture and shutter. SLR cameras have three key factors. One is ISO. Usually, the sensitivity value is expressed directly after ISO. For example, ISO 100 is considered as low sensitivity, while ISO6400 is considered as high sensitivity, high sensitivity and light sensitivity. If you give it a little light, it can be felt and fully exposed. Those with low sensitivity are not sensitive to light, maybe the light you give is not exposed at all.

One is that the aperture can control the blurring of the background of the picture, which is generally complete. The aperture values are as follows: f 1.0, f 1.4, f2.0, f2.8, f4.0, f5.6, f8.0, f1/kloc-0+. The more light in the same unit time, the larger the aperture f, the smaller the aperture, and the less light in the same unit time. And the light from the upper level is just twice as much as that from the lower level. For example, if the aperture is adjusted from F8 to 5.6, the amount of light entering will be doubled. We also say that the aperture is enlarged by one level, and the light flux of F5.6 is twice that of F8.

One is the shutter, which can shoot high-speed or low-speed objects. Shutter is a device used in camera equipment to control the time when light irradiates the photosensitive element. Its structure, form and function are important factors to measure the level of SLR. The shutter speed is small, the shutter opening time is less, the amount of light coming in is naturally less, and the amount of light read by the photosensitive element is naturally less; On the contrary, when the shutter speed is high, the amount of light read by the photosensitive element is also large.

A good photo must have a good composition, which requires you to learn while shooting, look at other people's works, and see how others compose and what kind of ideas they use, so that you can make rapid progress.

Of course, you have to take all kinds of photos. You can pat strangers on the street. If you like taking pictures, you can also consider buying a macro lens to shoot flowers and insects.
