拍摄时要调焦做到清晰成像,因此也会呈现出景深的大小,所谓距离越远,景深越深,距离越近,景深越浅;当然,这与镜头焦距有所关联,焦距长的镜头,景深小,焦距短的镜头景深大;同时,景深与光圈一样有关,光圈越小,景深就越大,光圈越大,景深就越小,大景深指照片的纵向清晰范围大,小景深指照片的纵向清晰范围小。所以,通过不同的 When shooting to focus to do a clear imaging, it will also show the size of the depth of field, the so-called distance, the deeper the depth of field, the closer the distance, the more shallow depth of field; Of course, this is related to the lens focal length, focal length lens , Depth of field, short focal length lens depth of field; the same time, the same depth of field and aperture, the smaller the aperture, the greater the depth of field, the greater the aperture, the smaller the depth of field, large depth of field refers to the vertical length of the picture clear, The vertical length of the picture is small. So, through different
