单反调光是新手摄影师学习中遇到的一个常见问题。很多人不知道如何依据不同的普通光圈值来调整光圈值。咱们应该知道光圈的不同会影响光的数量和景深,所以今日咱们学会了如何依据场景来调整光圈的巨细。
SLR dimming is a common problem for novice photographers. Many people don't know how to adjust the aperture value according to different ordinary aperture values. We should know that different apertures will affect the amount of light and depth of field, so today we have learned how to adjust the size of apertures according to the scene.
首先,如何调整单反的光圈?单反光圈越大,f值越小,单反相机的取光量越大。假如咱们处于弱光环境,由于光线缺乏,为了照亮全景画,咱们能够适当地运用大光圈,然后提高快门的速度。
First of all, how to adjust the aperture of SLR? The larger the SLR aperture is, the smaller the F value is, and the greater the amount of light taken by the SLR camera. If we are in a weak light environment, due to the lack of light, in order to illuminate the panorama, we can properly use a large aperture, and then increase the shutter speed.
第二,当咱们出去拍照人物的时分,特别是在一些冷巷,咱们会觉得当有很多人的时分,电影的主体现已很难从电影中出来,那么此刻咱们能够增加单反的光圈来带来一个小的景深。"同时,咱们也能够在拍照人物或静物时用大光圈聚焦主体,这样相片就会更美,梦中的布景也会更简练。
Second, when we go out to take pictures of people, especially in some cold alleys, we will feel that when there are many people, the main embodiment of the film is difficult to come out of the film, so at this moment we can increase the SLR aperture to bring a small depth of field. "At the same time, we can also focus the subject with a large aperture when taking pictures of people or still life, so that the photos will be more beautiful and the scenes in the dream will be more concise.
第三,单反孔径越小,f值越大,单反相机的采光越少。假如咱们需求拍照大场景的景物,咱们能够用一个大约F16的小光圈拍照,而光圈越小,清晰的范围就越大,这样咱们就能尽可能地看到全景。例如,当咱们拍照结业照时,为了让相片清晰,每个人的面部表情都需求被拍照,这是十分高的,所以咱们有必要运用小光圈,如F8,并确保每个人都在景深。
Third, the smaller the SLR aperture, the larger the F value, and the less light the SLR camera has. If we need to take pictures of large scenes, we can take pictures with a small aperture of about F16, and the smaller the aperture, the larger the clear range, so we can see the panorama as much as possible. For example, when we take a picture after graduation, in order to make the picture clear, everyone's facial expression needs to be taken, which is very high, so we need to use a small aperture, such as F8, and make sure everyone is in the depth of field.
第四,在光线充足的情况下,咱们能够先调整单反到手动模式,然后设置一个较小的光圈,通常在F8和F11之间,f8是许多摄影师选择的黄金光圈值。假如光线变暗,咱们能够调理f2之间的光圈。8和F4,同时,孔径还能够拍照浅层布景假化的效果。例如,当咱们拍照肖像时,咱们能够放大光圈;当咱们拍照风景时,咱们能够缩小光圈。
Fourth, in case of sufficient light, we can adjust the SLR mode to manual mode first, and then set a smaller aperture, usually between F8 and F11, F8 is the golden aperture value chosen by many photographers. If the light goes dark, we can adjust the aperture between F2. 8 and F4, meanwhile, the aperture can also take photos of the effect of shallow scenery falsification. For example, when we take pictures of portraits, we can enlarge the aperture; when we take pictures of landscapes, we can reduce the aperture.
要看到这些,你应该对单反的酒窝有一个基本的了解,并依据不同的场景调整光圈的巨细。当然,假如你想运用拍照的光圈值,或者你需求依据特定的场景、时间和拍照效果进行调整,上述值是一些适用的参考值。
To see this, you should have a basic understanding of the dimples of SLR and adjust the aperture size according to different scenes. Of course, if you want to use the aperture value of the photo, or you need to adjust it according to the specific scene, time and photo effect, the above values are some applicable reference values.
