锐化的目的是使影像看上去更锐利。如果你拍摄的是、JPEG格式的影像,那么你可以在相机的影像设置菜单中设置锐化选项,相机将自动根据设置数据锐化所拍摄的JPEG格式影像。如果拍摄RAW影像文件,那么就需要在RAW转换软件中锐化影像,或者转换后在PS中锐化,RAW影像不能在机内锐化。影像锐化后,像素之间的反差加大,给人的感觉是影像轮廓分明,有了更多的细节。 The purpose of sharpening is to make the image appear sharper. If you are shooting in JPEG format, you can set sharpening options in the camera’s Image Settings menu and the camera will automatically sharpen the captured JPEG image based on the settings data. If you shoot a RAW image file, you need to sharpen the image in the RAW conversion software, or sharpen it in the PS after converting, and the RAW image can not be sharpened in the machine. After the sharpening of the image, the contrast between the pixels increases, giving the impression that the image is well-defined and has more details.
