使用Photoshop CS6中新增的一系列滤镜创建更加真实可信的镜头模糊效果。摄影师们常用焦外一词来形容使用大光圈拍摄时画面前景与背景的虚化。每支镜头焦外的色彩弥散与虚化方式等,都有自己的特点。另外,在真实的焦外影像中,高光部分还可能呈现出不同的多边形,这取决于镜头的光圈叶片形状。但如果使用前面的教程中介绍的高斯模糊模拟镜头虚化效果,得到的高光将是没有任何特点可言的圆形斑点,让效果更真实。Photoshop CS6提供了一系列高级的模糊滤镜,能够帮助我们得到更加柔和、更加自然的虚化效果。
Create a more authentic lens blur using a new set of filters in Photoshop CS6. Photographers often use the word coke to describe the use of large aperture shooting the picture foreground and background blur. Each lens coke color dispersion and blur way, have their own characteristics. In addition, in real coma images, the highlights may also exhibit different polygons, depending on the lens's aperture blade shape. However, if you use the Gaussian Blur Simulation Lens Blur effect described in the previous tutorial, the resulting highlights will be circular spots with no features to make the effect more realistic. Photoshop CS6 provides a series of advanced blur filters to help us get more soft, more natural blur effect.
