照片剪裁

在放大照片的过程中，去掉原底片的一边或多边上的影象，从而改善照片画面结构的一种加工手段.摄影作品由于拍摄时受现场条件、照相机镜头视角范围等因素的限制，构图不能像绘画作品那样能充分发挥作者的主观能动性，往往不得不将与主题无关的东西摄入画面，因此常需要对已拍成的照片进行必要的剪裁，作某种意义上的第二次构图.照片剪裁是根据主题的需要，作者的创作意图和构图的规律剪切裁割去画面的某些部分，使主题更为突出，画面结构更为紧凑完善，以增强摄影作品的表现力和感染力.一般先在照片小样上画出剪裁线，而后按样放大.如果是作者直接放大，也可以在放大机的放大板上进行剪裁.剪裁只能部分改善构图，因此从事摄影创作不能过分依赖剪裁，关键是要在拍摄时就考虑好作品的构图.
