景深

指的是相机对焦点前后相对清晰的成像范围。在景深之内的影像比较清楚,在这个范围之前或是之后的影像则比较模糊。
景深表,下面调节光圈,上面有对应的景深,光圈数值的颜色对应对焦环上的景深刻度颜色。例如把光圈调为黄色的11,对应的景深就是上方两条黄色刻线中间的部分,用米和英尺两种单位表示

美乐时  LX 型相机的超焦距红点

景深英语:Depth of field, DOF)景深是指相机对焦点前后相对清晰的成像范围。在光学中,尤其是录像或是摄影,是一个描述在空间中,可以清楚成像的距离范围。虽然透镜只能够将光聚到某一固定的距离,远离此点则会逐渐模糊,但是在某一段特定的距离内,影像模糊的程度是肉眼无法察觉的,这段距离称之为景深。当焦点设在超焦距处时,景深会从超焦距的一半延伸到无限远,对一个固定的光圈值来说,这是最大的景深。

景深通常由物距、镜头焦距,以及镜头的光圈值所决定(相对于焦距的光圈大小)。除了在近距离时,一般来说景深是由物体的放大率以及透镜的光圈值决定。固定光圈值时,增加放大率,不论是更靠近拍摄物或是使用长焦距的镜头,都会减少景深的距离;减少放大率时,则会增加景深。如果固定放大率时,增加光圈值(缩小光圈)则会增加景深;减小光圈值(增大光圈)则会减少景深。

Depth of field 景深

The area within the depth of field appears sharp, while the areas beyond the depth of field appear blurry.
A macro photograph with very shallow depth of field
A macro photograph of a computer keyboard showing the depth of field variation, with very blurry (X, C, V), blurry (S, D, F, G), sharp (Z, E, R, T), and again blurry (2 to 6) keys.
A macro photograph of a Nokia 101 phone with extremely shallow depth of field of only a few millimeters and a strong bokeh effect.

In optics, particularly as it relates to film and photography, depth of field (DOF), also called focus range or effective focus range, is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a lens can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is impe****tible under normal viewing conditions.
