传统胶片摄影没有锐化的概念,也没有手段能够在后期锐化。“锐化”一词,是伴随着数码影像而产生的,也就是说“锐化”是数码的伴生物。那么,数码影像为什么要锐化呢?是不是意味着如果不锐化,数码照片就没有足够的清晰度,或者说数码照片的原始图像是发虚的?这个结论并非空穴来风,甚至可以说是基本事实。要回答数码照片为什么要锐化,首先要回答数码照片为什么会“发虚”。这里我分数码成像的结构特征、数码软肋——摩尔条纹和模糊计算、聪明的抉择三个部分进行详细介绍。
There is no concept of sharpening traditional film photography, nor is there any way to sharpen it later. The word “sharpening” is accompanied by digital images, which means “sharpening” is a digital companion. So, why digital image sharpening? Does not mean that if not sharpening, digital photos do not have enough clarity, or the digital photo is the original image of the hair? This conclusion is not groundless, and can even be said to be the basic fact . To answer why the digital photo sharpening, first of all to answer why the digital photo “Fat virtual ”. Here I divided the structural features of digital imaging, digital weakness - Moore stripe and fuzzy computing, intelligent choice of three parts in detail.
