　　单反拍人像推荐使用50mm或85mm定焦镜头。可以用光圈优先档，控制景深，拍出主题锐利、背景柔和的照片。相机模式转盘转到Av档，设置光圈值，拍人像最好使用大光圈的定焦头，使用镜头最大光圈拍摄，再逐级缩小光圈拍摄，已获得最佳影像。

　　单镜头反光相机（SingleLensReflexCamera），又称作单反相机，是指用单镜头，并且光线通过此镜头照射到反光镜上，通过反光取景的相机。所谓“单镜头”是指摄影曝光光路和取景光路共用一个镜头，不像旁轴相机或者双反相机那样取景光路有独立镜头。“反光”是指相机内一块平面反光镜将两个光路分开。第一台单反相机于1909年被研制出来，自从1970年代起，这项技术开始得到广泛应用，单镜反光相机成为了高级摄影爱好者和专业摄影师的新宠。

Turn the camera mode dial to the Av file, set the aperture value, it is best to use a fixed focal head with a large aperture for portraits, use the maximum aperture of the lens to shoot, and then gradually reduce the aperture to shoot, to obtain the best image.

　　A single-lens reflex camera (SingleLensReflexCamera), also known as a single-lens reflex camera, refers to a camera that uses a single lens, and the light passes through the lens to shine on the mirror, and the camera is framing through the reflection. The so-called "single lens" means that the photographic exposure light path and the framing light path share a single lens, unlike rangefinder cameras or dual-lens reflex cameras, which have independent lenses for the framing light path. "Reflective" means that a flat mirror in the camera separates the two light paths. The first SLR camera was developed in 1909, and since the 1970s, the technology has been widely used, and SLR cameras have become the new favorite of advanced photography enthusiasts and professional photographers.
