How to take digital photos?

This question is very difficult. Taking good photos is a long process. You can't be quick and quick.

All your questions are technical. Put it simply.

Aperture: a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens. Together with the shutter, it controls the amount of light reaching the film or photosensitive element. A large aperture and a small depth of field mean that the larger the aperture, the shorter the clear distance you can see. For example, the aperture of f2.8 has a clear distance of 2~4m, and the aperture of f22 may be 1~40m. Through the aperture, you can highlight the theme. Like people, the aperture is large and the scenery is small.

Sensitivity: it should be called sensitivity! Is the photosensitive speed of the film. Under the same conditions, the higher the numerical value, the shorter the exposure time and the larger the aperture. But the imaging effect will be poor, particles will increase and noise will increase. This is more concerned when showing the film. Generally, the number will be automatic, or you don't need to change it if you set it to 100 or 200.

Exposure time: there is nothing to explain, just the time when the shutter opens. It is usually used to take photos of different styles, such as showing movement and water flow.

There's nothing to say about focal length.

I'll just tell you how I learned it at that time.

Seriously, photography doesn't depend on what machine you use, professional SLR, card dc, old-fashioned film fool, disposable camera, lemon. Advanced cameras provide you with a creative platform. But be sure to remember that your photography level will never exceed your eyesight, that is, your appreciation level, and your understanding of beauty will never be possible!

So if you want to take a good photo, you must constantly cultivate your eyesight!

But don't expect you to look at the photos of the master and sigh for a month or two. You need to practice and study constantly to improve your appreciation. For that kind of long speech, how to write a composition and how beautiful it is are all artificial frames. Try not to watch it, it will restrict your appreciation. All you have to do is look at the reviews of those masterpieces.

On 150, I bought two photography textbooks of New York Institute of Photography. That book is quite good. You can buy it and have a look. It is divided into two volumes, including all photographic knowledge. It should be a classic textbook. I have read many books of this kind, but I still think new york is better and has more comprehensive knowledge. Although you don't cover some books, they can enrich your knowledge. I think the most classic is the three criteria for judging photos: 1 clear theme 2 attractive subject 3 simplicity.

If it is too expensive, you can download pdf online.

After reading these two books, there are basically no technical problems (the problem you asked above is absolutely solved), and you have a certain understanding of the basic methods of photography and know how to take good photos. Next, you have to turn around and travel around you (but you should pay attention to the beauty not only in the distance, but also beside you; Because your distance is right next to him), if you find beauty that you think is meaningful, shoot it, shoot it constantly, and choose it carefully when you get home. Don't force it! As long as the technology is not enough (insufficient exposure, focusing error, jitter blur, etc.). ), resolutely delete! There is no theme but picking out the essence of taking pictures! The rest should be screened with absolute critical eyes! Slowly, you will find that your photography level is also improving.

After that, I took the time to read special books such as portrait photography and animal and children photography, depending on my personal preferences.

In a word, your eyesight is very important! Practice is always the first! Keep studying! The pursuit of quality is as perfect as possible! Very picky about work! ……
