鱼眼镜头与小行星特效

摄影师Stephane Vetter在8月21日的日食时,于俄勒冈州马格纳湖的同一地点融合了白天和黑夜的景象,完成了这个精美渲染的『小行星』图像。拍摄需要大量的精心策划,这里是他通过Astronomy Picture of the Day解释他是如何做到的:
In this beautifully rendered “little planet” image, photographer Stephane Vetter fuses both night and day captured from a single location at Magone Lake in Oregon during the August 21st solar eclipse. The shot required tons of careful planning, and here’s an explanation of how he did it via Astronomy Picture of the Day:

这是一个小行星、全天空、双时延、数字融合的复合材料,从一个地方在夜间和白天捕获天体运动。在这个360×180全景图中,北部和南部分别位于图像的底部和顶部,而东部和西部分别位于左右边缘。在日食前一个晚上的四个小时内,当地球旋转时,在北天极(底部)环绕着星轨。在日全食期间,从日出到日落(上图)每隔十五分钟拍摄一次太阳,有时是偏食。然后将所有这些图像数字合并到在日全食期间拍摄的单个图像上。然后,可以看到太阳的明亮日冕在黑暗的新月(左上)周围闪烁,而金星同时变得容易看见(顶部)。中间的树,在相机下面,是道格拉斯冷杉。
This featured little-planet, all-sky, double time-lapse, digitally-fused composite captured celestial action during both night and day from a single location. In this 360×180 panorama, north and south are at the image bottom and top, while east and west are at the left and right edges, respectively. During four hours the night before the eclipse, star trails were captured circling the north celestial pole (bottom) as the Earth spun. During the day of the total eclipse, the Sun was captured every fifteen minutes from sunrise to sunset (top), sometimes in partial eclipse. All of these images were then digitally merged onto a single image taken exactly during the total solar eclipse. Then, the Sun’s bright corona could be seen flaring around the dark new Moon (upper left), while Venus simultaneously became easily visible (top). The tree in the middle, below the camera, is a Douglas fir.

所以,这就是典型的日全食、小行星、全天空、双时延照片,借助一棵冷杉拍摄,仅此而已。你可以在Vetter的网站上看到更多他的摄影作品。
So, just your typical full eclipse, little-planet, all-sky, double time-lapse photo by a fir tree, really. You can see more of Vetter’s photography on his website.

这样的『小行星』图像虽然具有鱼眼镜头的扭曲效果,但是并不一定需要使用鱼眼镜头拍摄。通过强大的图像后期处理技术,只要拍摄多个角度的照片,也可以合成出这样的效果。
