Backlight adds glow and atmosphere, but if you include the sun itself in the frame, one thing is bound to happen — lens flare. Flare shows up as ghosting or streaks. It can occasionally be used creatively, but for landscape photography it lowers contrast, distracts the eye, and seriously hurts the final image."},{"t":"h","x":"我拍摄过很多包含太阳的照片，而下面的这个技巧就是我消除光斑的必杀技！","xe":"I've shot many photos that include the sun, and the trick below is my killer move for eliminating flare!"},{"t":"img","f":"img-02","w":640,"h":12},{"t":"img","f":"img-03","w":640,"h":426},{"t":"p","x":"图一是我去年在广西拍摄的日落原片，由于太阳直射冲光的原因，画面中下部出现了令人讨厌的大面积的橘红色光斑，这种光斑是很难通过ps后期去消除的，而且光斑让该区域的画质损失严重。","b":false,"xe":"Image one is a straight-out-of-camera sunset shot from Guangxi last year. Because the sun shone directly into the lens, an ugly large orange-red flare appeared in the lower half. Flare like this is very hard to remove in Photoshop, and it badly degrades image quality in that area."},{"t":"h","x":"那该怎么办？","xe":"So what do we do?"},{"t":"p","x":"方法很简单：当你完成一张冲光照片的拍摄后，接着用手挡住太阳的部分再拍摄一张，这时由于光源被手挡住，强烈光线无法直射镜片组，那么就不会产生光斑了","b":false,"xe":"The method is simple: after capturing your into-the-sun shot, take a second frame with your hand blocking just the sun. With the light source covered, the strong light can't hit the lens elements directly, so no flare is produced."},{"t":"img","f":"img-04","w":640,"h":426},{"t":"h","x":"这一步的操作要注意两点：","xe":"Two things to watch in this step:"},{"t":"p","x":"1.用手遮挡时，由于画面亮度的大幅度下降，可能会导致曝光不足，这时就要通过调节曝光补偿去尽可能让两张照片亮度一致，减少后期拼合的难度。","b":false,"xe":"1. Blocking with your hand greatly reduces brightness and may cause underexposure — adjust exposure compensation so the two frames match in brightness, making the later blend easier."},{"t":"p","x":"2.拍摄时要注意对焦点的位置，如果焦点落在手遮挡的位置，就会出现无法对焦的情况。","b":false,"xe":"2. Watch your focus point: if it lands where your hand is, the camera may fail to focus."},{"t":"p","x":"接下来，将两张照片导入lightroom，在lightroom里要做的就是将两张图片调整的尽量一致，让后续的拼合更加容易。","b":true,"xe":"Next, import both photos into Lightroom and adjust them to look as consistent as possible, so the blend goes smoothly."},{"t":"img","f":"img-05","w":640,"h":320},{"t":"p","x":"（我们看到图一的色温是5400，色调+14）","b":false,"xe":"(We can see image one's white balance is 5400, tint +14.)"},{"t":"img","f":"img-06","w":640,"h":316},{"t":"p","x":"（图二的色温是4450，色调+12） 这是因为用手遮挡光源以后，图片会由暖变冷。","b":false,"xe":"(Image two is 4450, tint +12.)
