    四种夜景摄影的曝光方法
    2015/4/3 11:56:53
    一:一次曝光法在太阳刚落山,天空还有余晖,各种灯光已亮时,通过一次曝光完成夜景的拍这时天际间有霞光的衬托,色温低。艺考摄影培训色调暖,景物之间也有比较多的暗部细节和层次,各种灯光的亮度也给还没有完全暗下来的景物提供了照明,光厢度比较均匀,反差比较适中,在这种光线条件下用一次曝光法能获得非常完美的效果。
    A: a time exposure in the sun had just set, the sky and the light, all the lights are bright, the completion of a night shoot exposure when the sky glow background, low color temperature. Warm colors, there are more shadow detail and level of scene brightness between light, also has not completely dark scenery provides lighting, light box is relatively uniform, the contrast is moderate, can obtain perfect effect in one exposure in the light conditions.
    二:多次曝光法对同一景物进行多次曝光,具体方法是:启动照相机多次曝光功能,在天空还有余晖时对所要拍摄的景物完成第一次曝光,使影像中保留下被摄景物的外部轮廓、暗部层次以及天空云霞,注意曝光量要以天空的亮度为准。等天黑之后,所需灯光全部亮了,再进行第二次曝光,第三次曝光……,以获得满意的灯光照明效果。
    Two: repeated exposure to multiple exposures of the same scene, the specific method is: multiple exposure function starts the camera and light in the sky, when to shoot the scene first exposure, to keep the external contour image, the subject of the black level and the days of Kong Yunxia, pay attention to the exposure to the sky brightness shall prevail. So after dark, the lights are bright, and then a second exposure, third exposure...... Lighting, to get a satisfying effect.
    三:多次遮挡曝光法将快门调到B门,并用快门线锁定。手持遮挡工具(黑卡纸或黑色的绒布)遮挡住镜头,第一次曝光时要将光圈尽量缩小,上海摄影培训学校比较喜欢的如光圈16、22、32、45等,这样快门速度可调至数秒,有利于控制曝光时间,在天空还有余晖时,移开遮挡工具完成第一次曝光,曝光时间的长短完全由移动遮挡工具的手来完成,由于光圈小,曝光时间相对比较长,一般在1-2秒,手动移动遮挡工具完全可以做到,第一次曝光完成后就等待着灯光的出现。
    Three: the shutter cover many times exposure to B, and with the shutter line lock. A blocking tools (black cardboard or black velvet) blocked shots, the first exposure to the aperture to reduce, Shanghai photography training school is like such as 16, 22, 32, at 45, the shutter speed can be adjusted to the number of seconds, to control the exposure time and light, in the sky, away blocking tools to complete the first exposure, the exposure time by moving from tools on hand to complete, because the small aperture, exposure time is relatively long, generally in 1-2 seconds, can be done completely manually moving block tool, the first light after the completion of the waiting for the light.
    如车灯、闪电、固定的灯光、流动的灯火等,还可安排人工光,如用闪光灯或手电筒、车灯等照亮所需要突出的景物,或移动灯光制造出灯光流动的轨迹。每曝光一次就移开遮挡工具一次,曝光时间的长短根据被摄体亮度决定,一般在数秒左右,完成曝光后再次遮挡,如此反复苴到曝光次数和哦光时间满意为止。这样就可以得到一幅既有天空余晖,又有细节层次,而且灯火辉煌的夜景影像。艺考摄影培训:http://www.dysypx.com/
    Such as lights, lighting, lightning, fixed the flow and so on, can also be arranged by artificial light, such as flash or flashlight, lights and illuminated by the need to highlight the scenery, or mobile lighting to create light flow trajectory. Each exposure once removed from the tool once, the length of exposure time according to the decision of the subject brightness, generally within a few seconds, complete exposure again after occlusion, so as to the exposure times and light time satisfaction. This can be a picture of both the sky glow, and level of detail, and brilliantly illuminated the night image.
    四:多次移动曝光法在一个画面上完成多个不同景物重组的拍摄方法,具体做法是:在同一画面中分别对多个景物曝光。首先对主要景物进行第―次曝光后,移动照相机成变换镜头焦距对另外的景物如建筑物、灯光、充等分别进行第二次曝光,第三次曝光……在拍摄之前对画面要有一个合理的布局,那些景物安排在什么地方,最好画张草图。由于分别曝光的景物绝大部分是明亮的主体,所以上海摄影培训会做这样一个处理:把它们安排在画面的暗处,这样就会显得更加的突出。
    Four: multiple mobile shooting method exposure method completed more than a different image recombination in a picture, the specific approach is: in the same picture of a plurality of scenes exposure. The first section: exposure to the main scenery, moving the camera focal length of the lens to transform to another scene such as buildings, lights, charge were second exposure, third exposure...... Before the shooting to have a reasonable layout of the picture, the scene in what place, the best painting sketch. Due to exposure of the scene is the most bright body, so Shanghai photography training will do such a deal: to put them in the picture the dark, it will become more prominent.
