Dare to use a small aperture with a large aperture.

Photography aperture is the most important element of photography, in addition to controlling the amount of light exposure to meet needs, but also to obtain important means of specific artistic effect. .1, a large aperture and imaging quality of the unity of opposites. .Under normal circumstances, large aperture relatively poor image quality, but the maximum aperture of the lens when a new generation of image quality has been greatly improved, full use of large aperture imaging is a special aperture photography one of the most important elements of photography, in addition to control inlet .exposure amount of light to meet the needs, but also to obtain important means of specific artistic effect. .1, a large aperture and imaging quality of the unity of opposites. .Under normal circumstances, large aperture relatively poor image quality, but the maximum aperture of the lens when a new generation of image quality has been greatly improved, full use of available large aperture imaging features distinctive images. .Since this time the depth of field is small, easy to clearly reflect a particular region and other parts of the relative blur, highlight the subject. .Poor illumination, such as hand-held camera, using a large aperture can use high-speed shutter to prevent camera shake affect the imaging resolution. .Some photographers rarely use the maximum aperture, usually only f5.6, f4, should give full play to the characteristics of a large aperture, will have to dare to use the maximum aperture, large aperture standard lens such as the full available aperture f1.8, f1.4 and so the maximum .aperture, the telephoto lens should dare to use the maximum aperture f2.8, this time with the perturbation from the background and subject distance (the main background and farther away, the formation of large aperture the more obvious effect of the virtual background, and vice versa .Ran), etc., can be the effect of large aperture fully reflected. .Perhaps the biggest shot of the image quality is not aperture iris to medium well, but in this area and the resulting loss compared to the artistic effect is still worth it. .2, the virtual background. .Virtual background or usually choose a large aperture telephoto lens, as to how much would be suitable aperture it? .In fact, in addition to 200mm or longer telephoto focal length away from the lens, generally use the maximum aperture. .May wish to choose using a standard lens maximum aperture of f2.8 shooting even f1.4, the only way possible to obtain unique charm, the real subject and the background was separated. .Since relatively large depth of field digital camera, if not using the maximum aperture, the main it was difficult. .3, small aperture and long depth of field. .Using a small aperture to obtain a large depth of field is often used in films shooting method scenery, but also, and lens focal length, taken from the other factors combined. .If using a telephoto lens, when the 2-3 meters away from the camera, using f32 aperture, it will not get much depth of field. .In other words, as long as the subject and background are at infinity, even if a larger aperture, will be a great depth of field. .4, the aperture size varies by theme. .In figure photography, often used in large aperture, and landscape photography with many opportunities to the small aperture. .Shoot streams, water for the performance of the dynamic, you need to use 1/8-1/2 seconds slower this rate, do not use a small aperture will inevitably lead to overexposure; backlight boat shooting video and other waves, such as the use of the f22, f32 such a small aperture ., small surface waves have a similar effect of addition of starlight mirror; shooting fireworks and other topics, the need for 1 / 2 sec -1 sec exposure time to perfect the performance of fireworks shape and, therefore, need to choose a small aperture. .5, a small aperture should be used with a tripod. .Still shooting scenery and other topics using the small aperture on the imaging resolution requirements are relatively high. .Illumination in the middle with f22 aperture, shutter speed is often at 1 / 30 seconds, no tripod, handheld camera, often due to camera shake, physiological factors affecting the clarity of movement, so use a small aperture at low illumination .To take full advantage of relying on a variety of materials, reasonable hold the camera. .If using a digital camera, can increase the sensitivity to be remedied..
