我们被卫星塞满的夜空图像
Image of Our Satellite-Choked Night Skies

摄影师Brendan Larsen在塔拉纳基山上空拍摄了578张每张8秒的照片,历时两小时,然后在Photoshop中手动叠加工约45小时。最终合成图显示约14450条卫星轨迹,来自约1400颗卫星。Larsen强调这张图像不是AI生成的。摄影师 Vincent Laforet称其为重要照片,并对卫星会破坏长曝光感到 dismay,质疑是谁允许了这种卫星活动。

Hacker News 上的一段讨论围绕一张 Kottke 图片展开,图中显示了两小时内叠加的卫星轨迹。一些评论者认为经 Photoshop 编辑的图片具有误导性,称擦除恒星并合成轨迹夸大了问题。支持者说它准确描绘了卫星路径,反映了常见的天文摄影实践,并且是具有挑衅性的艺术。批评者尤其指责“卫星密布”的标题以及其作为纪实证据的呈现方式。其他人指出低地球轨道日益拥堵、卫星可见以及发射活动增加。讨论还提出轨道空间是否为有限资源,以及公司是否应为其使用付费。链接包括卫星追踪工具。

To create this composite image, photographer Brendan Larsen captured almost 600 photographs over a two-hour period and then manually stitched them together.

This is the most time-consuming photo edit I’ve EVER done!

I left my camera photographing the night sky over Mt Taranaki for nearly TWO HOURS, capturing 578 photographs.

The result? An estimated 14,450 satellite trail appearances, representing approximately 1,400 individual satellites! 😱

I manually masked in EVERY SINGLE TRAIL from the original photographs — approximately 45 HOURS of editing to create this one image!

The Guardian has more on how he created the image (which, despite many online commenters’ beliefs, is not AI):

Larsen, 51, says he set his camera up to take an unlimited number of eight-second-long shots, with a two-second gap in between each photo. “I left her running for two hours and captured 578 photos … That was the easy part.”

The hard part came next. Larsen spent about 45 hours layering the individual photos – each of which contained about 25 satellites – over one another, using Adobe Photoshop. Much of the time was spent painstakingly erasing stars, to reveal the satellites.

“I could start to see the pattern emerging and realised: ‘Wow, this looks really awesome.’ I knew if I carried on it would look even better and more impressive in terms of satellite numbers.”

Fellow photographer Vincent Laforet called Larsen’s image “an important photograph”:

I was initially startled. Then confused. Then fascinated all in quick succession.

And then I felt a deep sense of betrayal once I realized that what I was tracking with my eyes were a series of small satellites. And btw: that they likely had ruined my long exposure that I was capturing at the time.

I remember asking in the moment:

Who gave anyone permission do this?
