Novice SLR, Nikon D7000, took a few photos today and found some problems of my own. Ask the master: 1, the focus is always inaccurate.

1. As for the problem of inaccurate focusing, D7000 has 39 focusing detection points. Novices often don't pay attention to one of the viewfinder when focusing (some focusing modes can have more than one). Only when the subject is in the focus of the highlight can the subject be focused. Different focusing modes are different, so read the instructions carefully and explore the experience. It's best to use the single-point focusing mode first, and then press the shutter to lock the focus and don't let go of shooting.

2. Most photographers use RAW format to store picture files. This format records the original information output by COMS, and has not been processed by the internal processor. There is no modification in white balance, color saturation, contrast and sharpness, and there is much room for adjustment in the later period. But the only thing that needs attention is that the exposure conditions should be correct. If there is obvious overexposure, it cannot be improved later.

3. Photography is the plastic art of light and shadow. No matter the composition, the use of light, the control of depth of field, and the capture of wonderful moments, you need some cultivation. In the same scene, experts can often make excellent films. None of this can be achieved simply by post-production. It is equally important to watch other people's excellent films, carefully study their composition, the use of light and equipment, and improve their artistic accomplishment.
