Shooting skills of mobile phone with large aperture

What are the advantages of a large aperture?

The smaller the value after f, the larger the aperture. The function of the aperture is to determine the amount of light entering the lens. The larger the aperture, the more light enters. On the contrary, the smaller. Simply put, under the condition of constant shutter, the larger the aperture, the more light enters and the brighter the picture; The smaller the aperture, the darker the picture.

Next, let's take a look at the skills of using a large aperture fixed-focus lens.

Many students will ask novices what lenses they should buy, one of which is a large aperture fixed focus lens.

Advantages of large aperture

If you know about photographic exposure, you must know that the larger the aperture, the more light will enter at the same time, which can keep your photos clear in low light environment (such as indoors, at night, etc.) and make them look better. ) without increasing sensitivity.

In addition to increasing the shutter speed, another function of the large aperture is the depth of the scene. Shallow depth of field can not only highlight the subject, but also make the photos full of poetic and picturesque beautiful scenes. If you add some tricks, you can use the large aperture to shoot scattered scenes of various shapes, which is very interesting to shoot in festivals!

When many students see the word "fixed focus", the first thing they think of is that the fixed focus lens can't zoom, which is very inconvenient. There is no doubt that not zooming will bring inconvenience, but if the environment permits, you can not only achieve zooming effect by moving your body, but also let you develop the habit of thinking more and finding more angles, and improve your photography skills. Another advantage is volume and weight. Generally speaking, a fixed-focus lens is simpler than a zoom lens, so most fixed-focus lenses are light in weight, small in size (such as a standard 50mm fixed-focus lens) and have clear images. The fixed-focus lens rarely produces distortion, which avoids the trouble of later maintenance.

Therefore, under the factors of cost performance, volume and weight, the large aperture fixed-focus lens is very suitable for beginners. Especially those low-priced fixed-focus lenses, I suggest that students can consider starting and enjoy the fun brought by the large aperture!

Shooting skill

(1) Be serious and focused

When the aperture is fully open, the depth of field is very shallow, so you need to focus carefully. Slight movement will blur the subject.

Choose the right theme

Large aperture has the characteristics of depth of scene, so you may wish to choose subjects that can make use of shallow depth of field when shooting, such as portraits and close-ups. When shooting landscape photography, you can use the object (focus) to set off the scenery (scattered scenery) and increase the subject matter of shooting.

(c) Do not abuse shallow depth of field.

Although the shallow effect of large aperture is attractive, don't abuse it. For example, if the depth of field is too shallow, the background will become blurred, and the reader will not know where you are at all, which will lose its meaning.

When the aperture is fully open, the depth of field will become very shallow, and the reader may not see the main body of the photo, so don't abuse the large aperture.

(4) Walk around to find the angle.

Because fixed focus is not as convenient as zooming, you can move more when shooting, and it is very beneficial to improve your photography skills to explore interesting angles and things with your photographic eyes.
