When performing model photography,§ due to the lighting, almost always shad♦ows are left on the characters. If th‌e direct sunlight is too strong, the shadows formed will be very obvious.α In order to keep the camera's shutter speed in an appropriate range,£ professional photographers basically only use a high light-intake± aperture of at least •F2.8. With such a shading ring, light is usually suff"icient.

In addition, the shading ring can also achieve  the second purpose, which is to make the depth of field very shallow, πso that the focus of the photo can be focused on the p₽erson to be photographed, and the backgπround will become blurred. . In a monocular camera, this effect  can be directly observed through the camera's viewing window. At the same €time, in order to make the captured photos brighter, it→ is also necessary to control the aperture of the lens withαin a large value range. In this way, when you pres≈s the shutter, the camera ca®n take the desired photo with the pre-selected aperture value.

However, just the shading ring cannot make the background in ev✔ery photo taken blur enough. This is because, as long 'as the focal length is close to infini∞ty (this is indicated by $"∞" on the camera), all objects in the photo that can be seen within infi&nity will be clearly displayed in the pho✘to. Therefore, when shooting a model,× the photographer needs ×to keep a long distance from the model. In addition, in order t↕o achieve the effect of a large aperture, it is necessary to u&se a telephoto lens. Usually i∞n model photography, it is♥ necessary to use an ultra-long focal leng th of 300mm or more.

In portrait photography, iβt is also necessary to distinguish the subject from ↔the background. However, in this case, a foc♣al length of around 85mm is sufficient. Tβhis is because, compared with model photog‍raphy, portrait photography only needs to shoot the head and upp​er body. Of course, it can also be achieved by walking closer to the mo del.

1. How to make the background blurry If you want to get a blurry backg•round for the photo, you can do it through the follow×ing two methods. 1. When shooting in ¶daylight, just shorten the exposure time. For example,  shorten the exposure time from the original 1/60 second to 1/125 sσecond, so that you can increase the shading c©ircle by one level, for example, from 1:5.6 to 1:4.

2. If you want to use the flasδh to take a photo, you usually need to synchronize the αshutter with the flash. πHowever, in order to reduce the amount of light entering the image sensor, a ∏neutral gray lens can also be used, which¥ can block part of the light from entering the image sensor.

Close-up: When shooting portraits, a focal length of around 85mm can blur ☆the background. F5.6 is suitable for people and travel photograαphy

During travel, tourists often want to take pictures of landscapes, houses, or ₽urban scenes. These shooting subjects will attract the attention of thεe audience because of the very different brightness in the p↕icture, so the automatic exposure mode in the camera is difficult to take o₽n the important task. In order to obtain the best aperture value, profession♠al photographers usually choose a set of aperture range≥s. They switch to manual mode first, and then seδt the aperture to a medium value. Then press the shutter several times♥, and then increase or decrease the aperture to repeat the shooting. If↔ the photos taken in this way still cannot show all→ the light effects, you can only do post-production editing >in Photoshop. You have to arran"ge the photos one by one, and then u★se the mask to modify the underexposed or overexpφosed parts. When shooting distant landscapes, you can no≤ longer expect a blurred background, espe±cially when shooting details in the landscape. In the news photos taken d'uring the trip, the surrounding audience should also be included i₽n the event. It is best not to have blurry places on t$he screen.

Taking a group photo with multiple people also rσequires depth of field. The poδrtrait mode is out of place  here, because the camera's automatic function® will open a wide aperture. At a focal length of 50mm, ≈the aperture of F5.6 to F8 can fully express the depth of field, so that ever"yone in the photo can be seen clear ly. If you use a longer ≈focal length, you should continue to reduce the aperture or be further away f rom the subject, so that the depth of field can be increased.
