How does the camera shutter speed affect the brightness and clarity of photos?

There are also aperture size and ISO size that affect the brightness of photos!

Generally, hand-held shooting, to get very clear photos, it is recommended to 1/2n seconds, where n is the focal length, and tripod is also very important!

How to take clear photos:

1) The first step to highlight the subject and composition is to find an attractive landscape. Photography is not simply picking up the camera and pressing the shutter. Before you press the shutter, you should ask yourself, what attracted you to this scene? Is it a color? Cloud? Reflection? Or sunset? ? After determining the theme, the next step is how to express it. Usually, the subject should be large enough to attract attention. Theme? It's too small to be the subject. At this time, it is necessary to use a longer focal length or post-cutting to deal with it. Highlight the subject, so that the photo will? Have a soul.

2) Since we want to avoid being in the middle, we should know the so-called "trisection", that is, the so-called "golden section". "Cut" and "Nine-grid Three-Point Rule" are the basic rules of composition, which means: put the picture in the horizontal direction1/3,2/3? Draw two horizontal lines and two vertical lines vertically at 1/3 and 2/3, and then try to place the scene at the intersection.

3) Conciseness In fact, photography is' subtraction', that is to say, it is best to remove all the objects irrelevant to the theme from the picture, and the simpler the better. Especially for beginners, composition should start with simplicity.
