我们教你使用Photoshop的堆栈功能合成多张照片,模拟长时间曝光才能实现的星轨效果。想在夜间记录斗转星移留下的轨迹,正常情况下需要长达数分钟之久的曝光才能实现。但对于数码相机,这样的长时间曝光必然会造成严重的噪点问题。最简单的解决办法就是拍摄一连串曝光时间较短的照片,然后在Photoshopp将它们合成为一张单独的
We teach you to compose multiple photos using the Photoshop stack function to simulate the orbit effects that can be achieved with long exposures. Want to record the trajectory of the twinkling of stars in the night, under normal circumstances require up to several minutes of exposure can be achieved. But for digital cameras, such a long exposure is bound to cause serious noise problems. The easiest solution is to take a series of photos with a short exposure time and then combine them in Photoshopp into a single
