    今天我们山东艺考摄影培训机构哦小编给大家介绍的是初学摄影常见的几个误区:
    Today we Shandong art photography training institutions Oh Xiaobian to introduce the common misunderstandings of beginner photography:
    1、 画面影调模糊
    the picture fuzzy tone
    在排除了相机无故障和手震等原因后,就要检查镜头是否被灰尘覆盖或被污渍染涂。如遇到这种情况,切忌用嘴吹或毛巾擦。应用吹气球吹去镜头上的尘土,再用镜头刷拂去杂物,最后用镜头纸擦拭,使镜片明亮如新。如仍有汗渍、指纹和油垢,就要送相机维修店用镜头清洁液仔细清除。
    After eliminating the camera no fault and hand shock and other reasons, it is to check whether the lens was covered with dust or stains stained. If this is the case, do not use the mouth blowing or towel wipe. Application to blow the balloon blow away the dust on the lens, and then shot and brush brushed off the debris, the lens paper wipe, make lens bright as new. If there are stains, fingerprints and grease, it is necessary to send camera repair shop with lens cleaning fluid carefully removed.
    2、胶卷没有曝光
    the film is not exposed
    主要原因有二:一是傍轴取景相机拍摄时忘记揭镜头盖,取景器中景物清晰,但成像光线没有进入镜头,胶片没有感光。二是手动卷片的135单反相机装片不到位,卷片时没有注意看暗盒片轴是否在相应转动。由于片头滑脱,搬动卷片把手时,虽然快门上了弦,计数器照常计数,但胶片在暗盒中纹丝未动,计数器虽显示36张拍完,实际上没有一张胶片感光。
    The main reason has 2: one is near the axis framing cameras forget exposing the lens cover, viewfinder scenery is clear, but the imaging light entering the lens, the film is not sensitive. The two is a manual winding 135 SLR camera with film is not in place, when not watching the cassette in the corresponding rotation shaft is. Due to the slippage of the titles, winding the handle move, although the shutter on the string counter as usual count, film in a cartridge threads did not move, counter, although Zhang 36 finished, not actually a photographic film.
    3、 主体人物模糊,背景清晰可辨山东艺考摄影培训

    有两种可能,一是手动对焦相机对焦时,焦点没有对着主体或是主体对焦后,在构图中又移动了位置,未重新对焦,使主体不在景深范围之内;二是使用自动对焦相机时,没有按快门“锁定”焦点再重新构图,使焦点在构图中向别处飘移。
    There are two possible, manual focus camera focus, the focus is not in front of the body or is subject to focus, in composition and move the location of the, not re focus. As a result, the subject is not within the range of depth of field; second is using autofocus camera, no press the shutter "locked in" focal point and then to composition, so that the focus in composition to drift elsewhere.
    4、用广角镜头拍出的照片四角发黑

    主要是由于闪光灯覆盖面与广角镜头的视场角不匹配。老式闪光灯设计的闪光覆盖面大都只能与35mm的小广角镜头配套,28mm广角镜头的视场角比35mm镜头大12度,因此使画面四周受不到光而发黑。防止的办法有二条,一是在灯光上加散光罩,使闪光成为散射光,以扩大覆盖面;二是用白纱布蒙住灯头,让光线散射,使整个画面都能均匀受光。
    Mainly due to the flash coverage and wide-angle lens field of view does not match. Old flash design of the flash coverage mostly with 35mm only little wide-angle lens supporting, 28mm wide-angle viewing angle than 35mm lens, big 12 degrees. Therefore, the picture around not affected by light and dark. To prevent the approach has two, one is in light with astigmatism cover, making flash became light scattering, to expand coverage; the second is covered cap with white gauze, let light scattering, so the whole picture can be affected by light evenly.
    5、  团体合影照片前几排清晰,后几排模糊
    the group took a few rows of a clear picture, after a few rows of Fuzzy
    凡是多排合影照,要保证每个人影像清楚,就要做到三点:一是选择性对焦。五排人合影,选择第二排的对焦;七排人合影,选择第三排人对焦。二是光圈不要设定太大,一般以f4-8为宜,以保证有足够的景深。三是快门速度不要低于1/60秒,以免有人头部转动使影像发虚。
    Any multi row group photo, to ensure that each person's image is clear, it is to do three points: first, the selective focus. Five rows of people a photo, select the second row of the focus; the seven row of people a photo, choose the third row of people focus. The two is not too much to set the aperture, in general, F48 is appropriate, to ensure that there is sufficient depth. Three is the shutter speed should not be less than 1/60 seconds, so as not to turn the head to make the image virtual.
    6、照片四角有黑影
    There are pictures, four shadow angle
    主要原因有二:一是遮光罩与镜头焦距不匹配。把50mm标准镜头的遮光罩用于28mm焦距的广角镜头就会阻挡进入镜头的光线。因标头的视场角为47度,而28mm广角镜头的视场角为75度。二是用28mm广角镜头拍摄时,原已在镜头上戴有一块UV镜,如再戴一块偏光镜的话,由于偏光镜是两片玻璃叠合而成,边框很厚,再加在UV镜的边框,必然遮挡进入镜头的光线,使照片四角发黑。用广角镜拍摄时如需用偏光镜,一定要先卸下UV镜后再装偏光镜,才能使画面均匀受光。
    There are two main reasons: one is the hood and the focal length of the lens does not match. The 50mm standard lens hood for 28mm wide-angle lens focal length lens light barrier will enter. Because the header field angle is 47 degrees, while the 28mm wide-angle lens angle is 75 degrees. Second, use a 28mm wide-angle shooting, already on the lens wearing a piece of UV, such as wearing a polarizer, the polarizer is two pieces of glass laminated together, border is thick, at the border of UV, inevitable occlusion of light entering the lens, photo corners blackening. With wide-angle shooting as with polarizer, make sure you remove the snap and then install the polariscope, in order to make the picture even by light.
